  @alexsh1 re-personalize the node that lost the checksum. Each node (including gw) has a unique personalization and checksum (possibly). Just because one node looses the checksum or gets a mismatch does not mean any other node has the same problem. Everything is stored in eeprom locally.

  @Trand Well, sorry, but nothing else comes to mind. If you have a scope or logic analyzer then you need to watch the actual signals on the wires and see what is happening. If you don't, then you should pick up a cheap logic analyzer. You can get one for $10 and it's invaluable for tracking down things like this. I don't know where you are based, but I see them on Aliexpress all the time.

  @karlheinz2000 said: But if I'm not using MYSB, I can flash a sketch with defined ID and this will work instantly in the network. Yes With MYSB I always have to do assign a new ID just to get the node to run the first time after flashing. Only true if EEPROM (i.e. ID address location) was cleared. Any chance to get MYSB to know, if a sketch is an flash? And start this sketch, which then will use the defined ID or request a new ID from controller and writes the eeprom? During booting, MYSBootloader calculates the FW CRC in flash and verifies it against the FW CRC stored in EEPROM (which is written after a successful OTA FW update) - if it matches, the sketch starts, if not, the bootloader remains active.

  @tekka Is there any changelog to it also or it was just made officially available again? although last online status was 22 AUG 2020, so anyone else can confirm anything about it? I'd just be cautious without confirmation.

  @emre299 when you click on Burn Bootloader, you get these errors avrdude: stk500_recv(): programmer is not responding avrdude: stk500_getsync() attempt 1 of 10: not in sync: resp=0x03 avrdude: stk500_recv(): programmer is not responding avrdude: stk500_getsync() attempt 2 of 10: not in sync: resp=0x03 So you verified the connections. Did you verify also with a multimeter? A wire can be broken internally Do you have another pro mini to verify the connections? I would try different settings like the normal settings 3.3V and 8Mzh externally, etc If this does not work, I have no ideas anymore...

  Video in OP was good for "beginner" but you very quickly run into other issues. For me it was getting confused by lots of talk about interrupts (in relation to "input" type sensors). All of Build pages for these type of sensors mention about interrupts only being available on pins 2 and 3 (assuming Arduino Pro Mini, etc.). Which only confused me further (at first). However maybe you are smarter than me. But look closely, most (all?) of MySensors code I have seen for "inputs" (door, motion, etc.) actually DO NOT use interrupts! Notice the code runs right in the main loop. Interrupts are only needed when you sleep the node! Everything I talk about here is for always powered nodes, where you do not need to sleep because you are not on batteries. For batteries you need to sleep to save power, and then we have to do things different. Then you will need to use the hardware interrupts, to wake the node from sleeping. But that I will call "advanced" and beyond the scope of this particular post here, which I am calling "intermediate". So, back to that... You can use any pin you want (almost) for inputs when you are not sleeping the node. OP video does mention about non blocking code, but he does not go into detail. I don't know why not, as it is not complicated. You simply do wait() instead of sleep(). Or, if you are combining one or more thing(s) that needs to "listen" all the time (lets say, an actuator/relay, and for fun let's add a motion sensor, too!), with something that needs to send() periodically (let's say a temperature sensor) then you just keep looping over and over checking all your inputs, and then only enter the output (temperature) part of the code every so many millis(). An example: void loop() { // put code here to check motion sensor (copy from loop() part of motion sensor sketch) // now we check if enough time has passed to check temperature, if so we enter this subroutine if ( millis() > millisLastTemperature + TEMPERATURE_CHECK_INTERVAL ) { // put code here to check temperature sensor(s) // Right before we exit temperature subroutine, note current time as last time temperature was sent. millisLastTemperature = millis(); } // That's it for main loop() } // the relay needs code to receive incoming messages void receive(const MyMessage &message) { // Put code here from receive() part of relay sketch } Doing this way, you could even combine multiple sensors (temperature, humidity, light, etc.) to take readings even on different intervals. Just duplicate that subroutine, and give each one their own <SENSOR>_CHECK_INTERVAL variable. Just remember to define all your variables at the top of the sketch, and when dealing with millis() you want to use data type of unsigned long. Speaking of which, I think you also must have some very basic programming or even logical skills. But there is a lot of information in Internet nowadays, so hopefully you can study and teach yourself enough to get by. Good luck, and don't hesitate to post if you run into trouble. Don't suffer along in silence and then give up, without saying anything to anyone. Ask me how I know.

  Thanks for the answer. I meant that Mysensors has ESP32 support but only in terms of WIFI. It supports e.g. stm32 with ENC or W5500 modules - and the question is whether and how to add ESP32 support with LAN8720 module. I am not considering using ESPHOME or MQTT - I want to have native communication with the controller that implements my control schemes on its side. I try to program KC868-A16 but it does not matter - the question is whether such support can be added in a simple way.

  @bgunnarb I like @eiten 's solution for you. Personally, I am not a fan of using cloud/public brokers. Thus I am curious about your system and there is something about it from which I can learn. I would like to understand why you cannot deploy your own mosquitto broker. I see your set up as 3 sensor groups defined by the channel used #define MY_RF24_CHANNEL ChannelOfSensorGroup Each sensor group has some number of sensors and one MQTT GW on ESP8266. On the MQTT side, do you distinguish between gateways by using a different host name? Something like: #define MY_MQTT_PUBLISH_TOPIC_PREFIX "mygateway-nOf3-out" #define MY_MQTT_SUBSCRIBE_TOPIC_PREFIX "mygateway-nOf3-in" #define MY_MQTT_CLIENT_ID "mysensors-nOf3" #define MY_HOSTNAME "ESP8266_MQTT_GW_nOf3" //#define MY_CONTROLLER_IP_ADDRESS 192, 168, 178, 68 #define MY_CONTROLLER_URL_ADDRESS "test.mosquitto.org" #define MY_PORT 1883 I must assume your controller (aka Home Assistant) discriminates between through which gateway the data is to flow by way of the different topic names. If my "something like" is correct, then changing brokers is changing the IPaddress/URL in your gateways and in your controller (though if the controller is Home Assistant, it may be a bother because the device-id's may change which will make a mess of all the work you've done in HA. This is why I like @eiten 's solution.) I hope it's all working for you again. OSD

  @OldSurferDude well, the ESP8266 is limited to 4 TCP clients in arduino IDE. This can't be really increased. I did som experiments and you can set it up to 15, but after the 5th client on my web server, I got a freeze. Maybe you got something wrong. #define MY_GATEWAY_MAX_CLIENTS 2 defines how many controllers (eg Home Assistant) can connect to the gateway, not how many sensors/MySensors devices. And yes, you can have multiple TCP gateways in HomeAssistant. I got an NRF24, an RFM95 long range and a RFM95 short range gateway (all based on ESP32) on the same Home Assistant. Regards, Edi

  @eiten said in Saving last known good state, but not in EEPROM: utility meter in home assistant This is exactly what I am seeking! Thank you! PS I truly enjoy reverse translating! It teaches me how to better understand my first language and it gives me alternate words to use in searches. So a second thank you! "Regelmässiges Zurücksetzen" would be best translated to English in this context as "Periodic Reset". In the English version of Home Assistant it is called "Meter reset cycle" (I remember seeing "keep dry" translated as "do not take in shower with you"

  IT WORKS I got a first working version, using an ATmega1284P running on MightyCore 2.2.2 (as soon as I began developement, they switched from Optiboot to Urboot in version 3.0.0, whicht does not include the copy_flash_pages function anymore, but I'm working on a work around there). Only thing I could not solve is to do a CRC check of the image after download... You can try it out here: https://github.com/eiten/MySensors/tree/FOTAInternalFlashTest It's not beautiful yet with much Serial.prints in it, but maybe it helps you if you find errors.

  I found procedure gatewayTransportInit(), it works great. However, I cannot find a procedure that will enable detection of a network connection at level mysensors. I noticed that disconnecting the network plug or resetting the W5500 (37 pin to ground) changes the device's IP address to 0.0.0.0 - then I call gatewayTransportInit() - but mysensor's library must have such procedures - please tell me how to diagnose ethernet connection.

  Thx for the hint. Unfortunately this didn't help me to find a solution for the compilation error. I simply don't understand the lines 105 and 106 in (MyHwLinuxGeneric.h). Can anyone explain me the C magic going on there? #define ATOMIC_BLOCK for ( ATOMIC_BLOCK_CLEANUP, __hwLock(); \ __atomic_loop ; __atomic_loop = 0 ) I think the problem is the "new"/different compiler version being used on the OrangePi 5. On my Raspberry Pi the code compiled without any problem.

  Depending what's connected to a relay, I wouldn't make it go on or off depending on the controller state. It can lead to dangerous behaviour and it's prohibited by law in my country. In all honesty I have my Sensors running for a long long time. It's stable and more reliable than anything else I have running in my home. But like @eiten says yo could write a sketch that queries for a variable. But I think I'd go for a controller side solution. That would "ping" my node and send a nottfication to my phone whenever the node can't be reached.

  @gerritv Thank you for pointing the problem. I was updating my code, while library was updated and found that i had funtion, that does not exists in library - i've added it in local copy in library, then it updated and my local patch was gone. I've investigated previosly mentioned PR - and must admit that later they removed that re-initialisation when reading. I will try a PR to slightly improve that behaviour, but looks like library is becoming abandoned. Now look it should work next way: after previous measurement done you must run lightSensor.configure(ONE_TIME_) so it starts measuring - this is shown in their example BH1750onetime.ino. Then we have to wait, but measurementReady() relies on _delay_ms, which (as i remember) won't tick during sleep so you can't sleep. We can sleep but we can't get exact measurement time for current settings. Soto save battery we sleep max time - which, according to library is 180ms. Then we get reading. On next cycle - repeat. As i understand maximum battery saving code will look like: void setup() { Wire.begin(); // Initialize the I2C bus (BH1750 library doesn't do this automatically) lux_init_status = lightMeter.begin(BH1750::ONE_TIME_LOW_RES_MODE); //init ONE_TIME - at same time it will start measuring, but we will ignore this and double-call start measuring if (lux_init_status == false) { send(deb_msg.set("ErrorInitLux")); //notify us about failure } } void loop() { if (lux_init_status) { //making it fail-safe - if BH1750 brokes then other sensors will still work lightMeter.configure(BH1750::ONE_TIME_LOW_RES_MODE); //this will start measuring, after it sensor will go into power-down mode //note, that configure has 10ms sleep built-in sleep(180); //this is guarantee time in this library with any config. We can't get that externally as for v1.3.0 long lux = lightMeter.readLightLevel(); //actually get results } sleep(SLEEP_TIME);//sleep between measurements } note that .configure() that is also called by .begin has built-in 10ms delay

  @ncollins Impressive! Looks as though you even modeled the exact shape of the coincell holder. And you apparently designed the 3D printer snap enclosures as well. Even just the 3D printed enclosure modelling is quite a task all by itself. I hope to one day evolve into doing that too, but for now the Hammond enclosures are going to be my short-term solution. The smallest Hammond is still not as small as what you've managed to produce, but at 36mm wide for an off-the-shelf ABS enclosure, it's too wide by only about 10mm. Still.... one day I want to 3D print an enclosure to be as small as possible.

  maybe this can be useful : https://forum.mysensors.org/topic/6948/synchronising-light-switch I use it with version 1requestState or 2 requestTime() on some sketches (I modified the structure, moved some parts to functions to make it more readable )

  @alowhum Sorry, I have abandoned this project. It didn't garner the interest I hoped it would, and I’ve moved on to other microcontrollers/radios/networks since then. This is hosted on GitHub’s free static hosting, so it should continue to work as long as they are in business, and it should work on devices as it was 5-6 years ago. But I won’t be supporting it and won’t continue to build on it. Glad to hear that you like it!

  @NeoX maybe your existing serial gateway connected to one of the servers, with usb over ip to your HomeAssistant controller would work?

  I've asked, because I cannot test it right now and thought maybe someone has done it before. In this case I will test it myself next week. Right now I have some code that compiles, so maybe it will also work Referring to multimessage feature, I don't see any application yet (maybe I need to understand it better). More important to me is auto ID assignment for RS485 which seems to be also finally merged. Great!

  I think I understand what is happening. The compiler compiles all source files it finds in the folder. So when compiling the sketch itself everything goes fine I think. When the compiler comes across the MyTinySensors.cpp, it tries to compile that file also but can't find the define MY_NODE_ID. So I think you should move these files to subfolders (like done in the MySensors structure), so they won't be compiled individually anymore. Sounds plausible right?

  @mfalkvidd: So you are right, requestEcho is the end-to-end echo parameter but end-to-end means something else what I thought. Meanwhile I tested the other direction: controller (node-red) ->mqtt -> gateway -> sensor_node message sending with ack turned on in mqtt message. I found that in this direction the sensor node sends back echo automatically to the controller through gateway and through mqtt. So it is real (full) end-to-end echo If the controller sending command to my-sensor node, but it is not that if the node sends data to controller (in that case gateway sends back echo to node). I haven't found a description in documentation about this behavior. Is it planned to add this feature to tell the gateway to enable pass through echo request to controller? So communication in both direction whould be symmetric. Thanks!

  OK, now I understand what you meant. And I was talking about immediately building an all-in-one gateway with W5100, RS485, NRF24 and RFM69. That would require 2 SPIs and 2 USARTs. Taking that into account the ATmega324PB would be a perfect match. And, indeed, I wanted to build it step-by-step and only wire the according MCU pins to pinheads to extend it later. The big downside of the ATmega324PB is the 5V voltage level @ 16MHz and the limited memory. I compiled the sketch from the all-in-one gateway and came up with about 95% flash usage. So there's not much space left for the future. And I think 16MHz would make sense for the gateway and 8MHz could be a bit slow. 12MHz@5V would be in spec, but 12MHz is quite uncommon.

  @skywatch My apologies for derailing the topic, yep, got two of the boiler feed and return also, and tapped into the trigger wire to notify boiler ON/OFF so Domoticz tracks the run time per day. 12 degrees is recommended across the radiator but it's not quite so simple, it also matters WHEN you get that differential - That's where the portable node came in. Plastic pipe clips held sensors on the inlet and outlet pipes of the rad, the downstairs 6 all had a 11-12c differential at around 16/17 minutes, but no way would the upstairs 3 get there before the boiler cycle ended (room thermostat), which I put down to longer pipe runs. I increase the rate on the thermo-valve (pressure agnostic) to get the same heat on the return at ca 18 minutes. Rinse/repeat the remaining 2, eh voila. Balanced, a nice little peak on the return flow temperature at the boiler, reduced gas bills and every room +/- 0.5 of it's set point. Actual differential of these 3 upstairs radiators will be WAY under 12 for a constant feed, but for a heat cycle of 19-25 minutes depending on outside temperature it's perfectly balanced before the cycle ends.

  @Yveaux Thanks! Nice graph. I will do something similar in Grafana. I think my MySensors device should also report every minute, perhaps using the highest sampled value. All values are sent to MQTT by my gateway and my Home Automation will store the time value pairs in influxdb. Right now I'm waiting for the hardware to arrive...

  @pillarama I don't know about FOTA, but I see no reason why it would not work. I guess it depends what you do with it! I like being able to burn bootloader from within arduino ide and not having to swap to avrdudess et al - now I can boot load and program in the same window. I was amazed at how easy it is to install and use. No need for fuse calculators, just choose clock speed, internal or external and brownout and click burn. I do hope to try FOTA in April (real life allowing) and so will comment more then.... Only snag is it dosn;t work with the ardudriod on android, I have contacted the dev of that app and sent the error message but as yet no solution. Maybe it will be possible in the future to do all this from phone and needing PC..... It is very close.

  Hi @Necromant, thank you for your comments regarding the RPD feature of the nRF24+. I have done some experiments with it. The result is a new tool TrafficDetectorRF24, which is available in my MySensors.Tools repository. The tool scans a single channel and outputs the current status via a debug pin. This can be used to connect a LED or better an input of a logic analyser. At first I tried to use the RPD feature based on the MySensors example PassiveNode. Unfortunately, that didn't work at all for me. I then adapted the code from Rolf Henkel Poor Man's Wireless 2.4GHz Scanner for my purposes. The detector works quite accurately (resolution approx. 140us) so that you can usually detect the transmitted telegram and the ACK response of the receiver individually: I hope you have more success in your attempts with the RPD feature.

  In case someone is interested in the code for mysensors mqtt gateway using the DS2482.h library from https://github.com/paeaetech/paeae. The temperature conversion code is from example. I am omitting the mysensors setup. ... #include <DS2482.h> #include <Ethernet.h> #include <MySensors.h> #include <Wire.h> DS2482 ds( 0 ); //channels ds2482-800 is 0 to 7, DS2482-100 is just set 0 byte dsData[8]; //holding for onewire capture byte dsAddr[8]; //1wire wire address and CRC MyMessage msgAddr( 0, V_ID ); MyMessage msgTemp( 0, V_TEMP ); void setup() { //Uses Wire library to communicate with DS2482 so be sure to call Wire.begin() before using the library. Wire.begin(); ds.reset(); } void presentation() { // Send the sketch version information to the gateway and Controller sendSketchInfo( SKETCH_NAME, SKETCH_MAJOR_VER "." SKETCH_MINOR_VER ); } void loop() { #ifdef MY_DEBUG Serial.println( "DBG: loop start" ); #endif ds.wireResetSearch(); ds.wireReset(); ds.wireSkip(); //need to send high power to bus?? Adding 5 volts to devices makes it work. ds.wireWriteByte( 0x44 ); //convert temperature on all devices delay( 1000 ); byte sensorId = 0; while( ds.wireSearch( dsAddr ) ) { #ifdef MY_DEBUG Serial.print( sensorId ); Serial.print( " : " ); #endif char sensorAddr[17]; //eg. 280838211713012D for( int i = 0; i < 8; i++ ) { sensorAddr[i*2] = ( dsAddr[i] >> 4 ) + 0x30; if ( sensorAddr[i*2] > 0x39 ) { sensorAddr[i*2] += 7; } sensorAddr[i*2+1] = ( dsAddr[i] & 0x0f ) + 0x30; if ( sensorAddr[i*2+1] > 0x39 ) { sensorAddr[i*2+1] += 7; } } sensorAddr[16] = '\0'; //always zero terminate string #ifdef MY_DEBUG Serial.print( sensorAddr ); Serial.print( "\n" ); #endif send( msgAddr.setSensor( sensorId ).set( sensorAddr ) ); #ifdef MY_DEBUG Serial.print( sensorId ); Serial.print( " : " ); #endif if ( ds.crc8( dsAddr, 7 ) != dsAddr[7] ) { Serial.print( "CRC is not valid!" ); return; } /* //test if device code DS18B20 if ( dsAddr[0]==0x28 ) { //test if device code MAX31850 if ( dsAddr[0]==0x3B ) { */ //read temperature data. ds.wireReset(); //ds.reset(); ds.selectChannel( 0 ); //necessary on -800 ds.wireSelect( dsAddr ); ds.wireWriteByte( 0xbe ); // Read Scratchpad command //display hex values of scratchpad for ( int i = 0; i < 9; i++ ) { // we need 9 bytes dsData[i] = ds.wireReadByte(); #ifdef MY_DEBUG if ( dsData[i] < 16 ) { Serial.print( "0" ); } Serial.print( dsData[i], HEX ); #endif } //convert to decimal temperature int LowByte = dsData[0]; int HighByte = dsData[1]; int TReading = ( HighByte << 8 ) + LowByte; int SignBit = TReading & 0x8000; // test most sig bit if ( SignBit ) // negative { TReading = ( TReading ^ 0xffff ) + 1; // 2's comp } float Tc_100 = (double) TReading * 0.0625; if ( SignBit ) { // If its negative Tc_100 = 0 - Tc_100; } //print temp for each device #ifdef MY_DEBUG Serial.print( " : " ); Serial.println( Tc_100 ); #endif send ( msgTemp.setSensor( sensorId ).set( Tc_100, 2 ) ); sensorId++; } #ifdef MY_DEBUG Serial.println( "DBG: loop end" ); #endif delay( 60000 ); } I am of course happy for any feedback.

  I finally got it working reading through google searches. I'd like to provide how I did it for anyone that may run into a similar issue in the future. While looking for this solution, I saw at least one person who had the exact same issue and their problem went unresolved. Raspberry Pi 3 is connected to Arduino Mega through regular serial link. Raspberry pi uses uart pins that map to Serial0 in raspbian. On Arduino Mega I use Serial2 pins (16,17). There's a voltage divider circuit between the two that reduces 5v to 3.3 for the pi. I compiled my gateway on pi with below: ./configure --my-transport=rs485 --my-rs485-serial-port=/dev/serial0 --my-rs485-baudrate=9600 On Arduino I have these define lines: #define MY_DEBUG #define MY_DEBUGDEVICE Serial #define MY_RS485 #define MY_RS485_HWSERIAL Serial2 #define MY_NODE_ID 1 #define MY_RS485_BAUD_RATE 9600 #define MY_RS485_DE_PIN -1 I'm not an expert on this by any means, but out of everything I tried, this is what worked for me. There are still some remaining issues: Possibly due to line noise or voltage being low on Arduino, I've had one crash that made Arduino print gibberish on serial and it stopped transmitting anything at all. I use Home Assistant and it seems to give up on MySensors if it doesn't receive anything in a while. Requires restart of HA core. Not very reliable. I still welcome any insight into this process and any alternatives/recommendations. I'd like to make this as reliable as possible, but my knowledge of these systems and electronics is limited.

  @canique said in RFM69 sensitivity vs packet loss: The bold part of your statement is plain wrong. RxReady means that enough preamble (or any other data like noise) has been received to read RSSI and optionally tune AGC/AFC. [This is why -if you set the wrong RSSI Threshold- you permanently get RxReady interrupts.] The preamble is there to help adjust the AGC/AFC. That's the purpose of the preamble. So your preamble must be sent before the RxReady interrupt, not after it like you claim. Of course you can send the preamble after the RxReady interrupt (like you can pour soup over your salad) but then you have a potentially wrong AGC/AFC setting. It's just not meant to be. Yes ,good clarification. I didn't say it right. The desired scenario would be where the preamble signal strength is much higher than the background noise and the RSSI threshold is set high enough that only the preamble triggers the rxReady, not the background noise. By the way, why are there two RSSI sampling phases back-to-back (each of length Trssi)? What role doe the second RSSI sampling serve?

  So, I finally got this done and it works just like I want it to. I used my initial schematics (plus radio, of course) and this code: /** * The MySensors Arduino library handles the wireless radio link and protocol * between your home built sensors/actuators and HA controller of choice. * The sensors forms a self healing radio network with optional repeaters. Each * repeater and gateway builds a routing tables in EEPROM which keeps track of the * network topology allowing messages to be routed to nodes. * * Created by Henrik Ekblad <henrik.ekblad@mysensors.org> * Copyright (C) 2013-2015 Sensnology AB * Full contributor list: https://github.com/mysensors/Arduino/graphs/contributors * * Documentation: http://www.mysensors.org * Support Forum: http://forum.mysensors.org * * This program is free software; you can redistribute it and/or * modify it under the terms of the GNU General Public License * version 2 as published by the Free Software Foundation. * ******************************* * * REVISION HISTORY * Version 1.0: Yveaux * * DESCRIPTION * This sketch provides an example of how to implement a humidity/temperature * sensor using a Si7021 sensor. * * For more information, please visit: * http://www.mysensors.org/build/humiditySi7021 * */ // Enable debug prints #define MY_DEBUG #define MY_OWN_DEBUG #ifndef MY_OWN_DEBUG //disable serial in production compile, potentially saves few uA in sleep mode #define MY_DISABLED_SERIAL #endif // Enable and select radio type attached #define MY_RADIO_RFM69 #define MY_IS_RFM69HW #define MY_RFM69_NEW_DRIVER #define MY_NODE_ID 5 #define CHILD_ID_TXT 0 #define OUTPIN 8 #include <MySensors.h> #define SKETCH_NAME "media_pc_switch" #define SKETCH_MAJOR_VER "1" #define SKETCH_MINOR_VER "0" static bool metric = true; MyMessage msgTxt(CHILD_ID_TXT, V_TEXT); void presentation() { // Send the sketch version information to the gateway and Controller sendSketchInfo(SKETCH_NAME, SKETCH_MAJOR_VER "."

  Just for the record. Using a lipo charger doesn't work as a ups. So if the battery is below a certain trashhold, and a circuit is connected to it. It will no recharge if the circuit draws over 600 ma (I believe that is for 5v. so I guess it's more for 3.3v). Andreas Spies posted a youtube video on this last Sunday. I'm keeping my eye on his progress. I think he will design a UPS for ESP and Atmel based boards. Also design note: I use a rotary encoder as user input. It just gives a better UX for dimable lights. But - haven't measured - the rotary encoder seems to draw quite a lot of current. I read it could be up to 60ma. I have some of those magnet based encoders laying around. But not sure if I want to use one. They are quite expensive, so I have better projects in mind for those. But they draw just a couple of micro amps. An alternative could be to switch of the encoder circuit with a fet. But I need to experiment some more with this.

I use a utility_meter. utility_meter: hourly_ok_gw: source: sensor.gateway_1_0_0 cycle: hourly hourly_err_gw: source: sensor.gateway_1_0_1 cycle: hourly This sensors will be sent to Grafana each hour just like any other sensor and you can create a graph there:

  @mfalkvidd probably, but the search range (channel, baudrate) will be large. I would start by just sniffing the spi communication to the nrf24 using a logic analyzer, to get the comms parameters and the data. Then configure another nrf24 to receive this data and work from there.

  I've opened an issue for that. https://github.com/mysensors/MySensors/issues/1452 According to API payload is same on ECHO message. I feel this should be handled/fixed in lib, but I have no idea how to do... If it is not possible to fix in lib, it shall not be allowed to send message with no payload anymore, which controller has to make sure then. @rejoe2 Regarding FHEM, at the moment we should keep it as it is. No payload is not the normal use case. I flashed gateway with 2.2.0 and this fixed the problem for me.

  I do not use signed messages, so I used the Signed flag in the MySensors packet header to implement selective MQTT retain state. Gateway is ESP2866 - no specific code. Code send from client: template<typename T> void reportMsg(const uint8_t & id, const mysensors_data_t & tag, const T & val, const bool retain) { MyMessage msg(id, tag); msg.setSigned(retain); send(msg.set(val), true); } Lite patch MyGatewayTransportMQTTClient.cpp: bool gatewayTransportSend(MyMessage &message) { ... bool retain = message.getSigned(); message.setSigned(false); ....

  @Yveaux Yes I had manually changed MyConfig.h to reflect the channel number I use. I thought I had read that was the way to do it. Okay thanks for putting me straight. Good to know it was just normal behaviour. I'll add it to each of my sketches in future. Thanks.

  Yes it is possible, using the SWDIO and SWDCLK pads. I programmed one to operate with MySensors using a black magic probe, but the J-Link also supports SWD programming. The tricky part is connecting to the pads. I just soldered on some wires -- not a very elegant solution, but it worked. You can get a reasonably priced J-Link EDU from Adafruit: https://www.adafruit.com/product/3571

  @tante-ju Sorry for the late reply, I have been away for a few days with work. While I am sure there will be more than one way to achieve your goal I have given a brief outline of the way i did it below. If all you want to do is request data from another node it should not need any more steps than @Sasquatch has listed above. Lets say we have node A with an id of 1 we also have node B with an id of 2 and it has a binary sensor with a child id of 3 Node A wants to know the the status of the binary sensor on node B So in your code on node A you will issue the request to query child id 3 on node 2 request( 3, V_STATUS, 2); The gateway will rout this directly to node B where you will need to have code to deal with the request in the receive(); function. In it's simplest form you could have something like this below. void receive(const MyMessage &message) { if (message.type == V_STATUS) { if (message.getCommand() == C_REQ){ // message is request // put code here to be executed when the message is from a request // most likely you will call a function that will get the requested // data and return it to node A. If you are expecting requests for more than 1 // sensor you can use message.sensor to test which sensor the request is for } else { // message is from gateway,process the message as per normal // put code here to be executed when the message is from gateway } } } in the scenario above node B only expects requests from node A or commands from the gateway so it is easy to check what has arrived. If the message is a request we can execute code to get the required data and send it back. if it is a command (C_SET) from the gateway then it will fall through to the else part of the statement and be available as per normal. To send back the Data you will need to use a node to node message. this can be done on the fly, the format is shown below /* Node to Node message format. * * * * * * : Id of sending : message : Destination : Destination : Payload * * : sensor : Type : sensor Id : Node Id : */ send(MyMessage(sendingSensorId, V_STATUS).setSensor(sensorId).setDestination(nodeId).set(true)); //send message to desitination node So using our example you would have. (As we are not trying to actually switch any sensors on node A we can leave out the setSensor() part of the message) send(MyMessage(3, V_STATUS).setDestination(1).set(true)); Being a binary sensor the payload would be set to either true or false. Now we have sent the data all that is left to do is catch it in the recieve part of node A. One way to do this is simply to test for where the message has come from, if it is from the gateway (node 0) or in our case node 2. void receive(const MyMessage &message) { if (message.type == V_STATUS) { if (message.sender == 0) { // check if message is from gateway (node 0) // put code here for normal gateway messages } else { // message is not from gateway so check to see if it is from node B if (message.sender == 2 ){ Put code here to deal with returning request } } } }

  I also want to highlight one problem of the arduino IDE, and that is that it is very local to your machine. It makes hard to share your projects with others or even to migrate to a different machine of yours. This may not be a problem for casual editions, but as soon as you have build 5 or 10 things this starts to be a concern. People should be able to store their projects whenever they want and not be tied to specific paths/configs on a particular machine.

  it's probably a stepup for newcomers, and certainly a late stepup like others said. Well, I'm very glad with my favorites IDEs, so I'm not interested in it too, even for testing. One of my top priority when choosing an IDE (like any other tool) is productivity, no matter where the tool comes from. Privacy is important too of course, but not a problem with IDEs. So I'm fond of Jetbrains, VS and VS Code, and a few free-to-use mcu manufacturers IDE for best xp

  Agree with @Yveaux. V_ARMED can be used in battery powered door sensors to preserve battery, or to reduce traffic. don't send V_TRIPPED if V_ARMED is not set. Sounding alarm is controller's decision.

  Update: After few hours with AVR dragon snooping execution paths I found that after each loop() radio is woken up by code executed after each loop(). My solution is to never leave loop() by creating infinite loop inside of it, so far, after 10 h everything runs stable. 8-10 years on a single 1/2AA Lithium thionyl battery seems possible

  @henk-herck - thanks for your reply and suggestions. I changed the pins to output and set them as high, but unfortunately it didn't change the outcome. In the end I soldered some wire into the OpenSprinkler's expansion board to help me get to that row of pins which allowed me to work around my issue. I'd never really looked at the Orange Pi range before and went a bit down a rabbit hole looking at them yesterday. They're quite interesting and I'll look into them a bit more today.

  @henk-herck said in Why is stropts.h included ?: the manufactures are not that interested There is this, which is true, and then there is outright hostility towards F/LOSS development, which is typically a product of dinosaur business model lock-in mindset (RPi, Nvidea, etc...), which I can only hope will finally die off sooner or later. @henk-herck said in Why is stropts.h included ?: amlogic ,allwinner ,rockchip are less known socs but have nice features Yes, personally I am well aware, but good to mention for others reading. Currently I am eagerly awaiting the release of the version of Helios64 (Rockchip based, IIRC) which is supposed to come with ECC RAM! This will eventually become my new 64-bit ARM ECC ZFS NAS (wow that was a lot of alphabet soup!).

  @ozrex, I don't want to assume your knowledge level. However the truth is that you will probably need to put together different bits and pieces from various threads in order to come up with your own custom solution (the A/C interface (IR) part, the battery part, etc...). Maybe it is worth it to create your own new thread, or maybe you want to keep researching / trying on your own a little longer first. The latter is admirable, and is the way I usually do it, too. Some times to a fault in my own case. Don't suffer along in silence if you are struggling to find the information, make a thread instead. If it becomes too difficult you may give up. We all need some small successes along the way to keep motivated and keep it fun. Probably best to create a new thread (I don't want to derail this one too much) but something you might want to look into is OpenMQTTGateway. I use it for my 433mhz, but it also supports RF, BLE, LoRa (and perhaps others in future) all on the same gateway! To me that was the way to go... And so far has been flawless for me.

  Besides what Bob (?) mentioned (you seem to be making progress, breadboard unreliability, specifics), I would point out that there have been a number of discussions about ACKs, re-sending, reliability, keeping stats of NACK percentages (as a possible indicator of some problem), etc. over the years. The most recent I can recall was probably this one that I learned about when @BearWithBeard mentioned it here in my evidence based radio testing method (and capacitors) thread. My thread is more about hardware and radio testing, but we get into the subject of software ACKs etc. there in my thread a bit, and also in the linked thread. Is that the sort of stuff you are looking for?

  Well I'm sorry you took it that way. By the time I happened along into the thread, you had already pronounced your diagnosis. I offered my thoughts into the thread, this way if your first diagnosis turns out not to be correct, you have other ideas to try. These issues can be complicated, and (I know from experience) some times what we think at first ends up not actually being the problem. As I said, I could be wrong anyway. @mhkid said in Node registration problem: And your comment was not based on any evidence it was just a feeling you had Each of us are chock full of thoughts, memories, things we learned which we are no longer consciously aware of. The sum total of all this "sub-conscious" thoughts and memories can manifest itself as a "gut feeling" but perhaps you are unaware of this. At any rate, it is not as if you need to be a "radio whisperer" or that this is some obscure subset of problems. Rather I would submit to you that these are the most common type of problems. @mhkid said in Node registration problem: you offered no solutions In fact I said "It sounded like radio propagation issues to me." No need for me to go into any further detail, if exchanging the gateway has solved the problem. However if you continue to experience problems, please share new information and we can continue from there.

  Good to her you found that point . Imo you'd better change also your receive functions to not react on "ack" messages (via "else" prior to message.type-comparison).

  Well.. The quick answer I guess would be Yes, it is possible. But I imagine you would need to know a little bit about how the different components work. I also use the LoRa library from Sandeep Mistry and if you take a look at the code that initializes the card you find the following: // check version uint8_t version = readRegister(REG_VERSION); if (version != 0x12) { return 0; } Which is using the function readRegister: uint8_t LoRaClass::readRegister(uint8_t address) { return singleTransfer(address & 0x7f, 0x00); } Which is using the function singleTransfer: uint8_t LoRaClass::singleTransfer(uint8_t address, uint8_t value) { uint8_t response; digitalWrite(_ss, LOW); _spi->beginTransaction(_spiSettings); _spi->transfer(address); response = _spi->transfer(value); _spi->endTransaction(); digitalWrite(_ss, HIGH); return response; } Which is using pretty simple SPI commands. So perhaps you could do the same and select the LoRa library if the version is 0x12 or else select the nRF library. I don't know if there is enough space on the 328p to load both the libraries? And if you want to use the mysensors library it would be more complicated i suppose..

  @monte, I've implemented in PR https://github.com/mysensors/NodeManager/pull/517 something going in the direction you pointed out. Before explaining just a simple assumption first: NodeManager is intended to run on a number of different boards, most of them with limited memory so this capability has to take this constraint into consideration (hence no json parsing, reuse of existing communication mechanism, capability disabled by default, etc.) Apart from this, I found a sort of compromise to enable/disable sensors, even remotely and optionally persisting the status across a reboot. All the implementation details are within the PR (down below, the PR also include other enhancements) feel free to provide comments here or on Github. Hope it could be useful to avoid reimplementing the entire logic from scratch

  Sadly it occured again a few minutes later, even after uploading the most basic arduino sketch (blink) in which I added a Serial.println. It appears sometimes it works , and sometimes not ! I ended up downloading the java IDE, which I can confirm works perfectly. There is definitely an issue with the serial monitor when using Arduino create web IDE (and not specific to mysensors debug mode). Hope this helps !

  I bought second arduino uno. And, first Arduino has example MotionSensorRS485, second Arduino has example GetwaySerialRS485. And i have got the same situation. So even Gateway on Arduino doesn't see MotionSensor. Next test i made, i disconnected MAX485 converters, and i connected UART pins from first arduino to the second one (UART = Rx(8) <-> Tx(9), Tx(9)<->Rx(8)) and GND. And i have got the same result. Gateway doesn't see sensor.

  @Puneit-Thukral I have a similar sensor ( PIR + BMP280 + other stuff). I don't use smartSleep ( Since this code is old, only sleep was available ) so I can't speak about the sleep part. Maybe you could try with regular sleep just to see if brings some diference... Regarding the BME280 (BMP in my case) , I didn't have to use the Wire.begin() / end(), and I use the same library as yours (Adafruit). Code is bellow, in case you want to compare yourself. /** * The MySensors Arduino library handles the wireless radio link and protocol * between your home built sensors/actuators and HA controller of choice. * The sensors forms a self healing radio network with optional repeaters.

  Maybe you can fill a global char array from within receive()? You’d have to handle quick successive calls in a good manner though.

  Did someone got the idea why 100% in Domoticz is 99% in MySensors? Is MySensors limiting dimmer to 99% or is this caused by Domoticz?

  @Stef9998 said in not understanding Smart Sleep: @rejoe2 I'm in the process of configuring an OpenHab instance, and the binding should support smart sleep Don't know about OH's abilities, I "just" did the FHEM implementation of that feature . That I don't understand. Why should the controller have queued messages when the node is sending the second type (going to sleep). The controller knows the node is awake (cause of first/awake message), so why should it start to queue them? It should just send them, and then when the controller knows, that a node will be asleep (second message) start queueing. The user or some automatics could create some message to be sent out at any point in time. But sending out any message only makes sense when the controller knows the node is actually listening - these are sparse blinks in time, so most of the time a message will be queued first (or let's call it retained to stick to mqtt conventions). Then the controller has to wait for a signal from the node side, but as described earlier, this should not be the "awake" message (meaning a sensor can deliver some values and so on), but the "will go to sleep" one (meaning: "I will stop talking now, but continue to listen for 500 ms now"). Hope the fog is clearing now...

  Welcome to the forum @DCEM ! https://forum.mysensors.org/post/78795 describes one way to do it. The node requests the value of a parameter from the controller, and sleeps for that amount of time. See https://www.mysensors.org/download/sensor_api_20#requesting-data for documentation on how to request values

  @matkor said in How can one use MyMessage class in library?: Switching both clashing functions ( wakeUp1(), wakeUp2() ) to static functions seems to fix linking for me. This sees to be deadend as there come more function name clashes, and i suspect linking problems come from magic done by arduino IDE. Current hack for me is include in arduino sketch my lib headers after including MySensors: #include <MySensors.h> #include <MyLib.h> and than inside library use only: #include <core/MySensorsCore.h> not sure if its right solution, if one has any better please share.

  isAck(): differentiation between sent and received messages

  The approach to differentiate the message did not work for my purpose: commands sent from Fhem are a set message requests return as set message Status message of the node (set message) returns as set message with Ack I.e. all are set messages (no differentiation possible) Because I use a counter to limit the resending of the status message from the node I used this counter to get to the destination. In short: If the reception was successful the counter goes to 0, the request to <0 and the send to >0. Here is my sketch, it is for switching several time controlled relays, for clarity I have removed the debug messages: /** * The MySensors Arduino library handles the wireless radio link and protocol * between your home built sensors/actuators and HA controller of choice. * The sensors forms a self healing radio network with optional repeaters. Each * repeater and gateway builds a routing tables in EEPROM which keeps track of the * network topology allowing messages to be routed to nodes. * * Created by Henrik Ekblad <henrik.ekblad@mysensors.org> * Copyright (C) 2013-2018 Sensnology AB * Full contributor list: https://github.com/mysensors/MySensors/graphs/contributors * * Documentation: http://www.mysensors.org * Support Forum: http://forum.mysensors.org * * This program is free software; you can redistribute it and/or * modify it under the terms of the GNU General Public License * version 2 as published by the Free Software Foundation. * ******************************* * * DESCRIPTION * The RS485 Gateway prints data received from sensors on the serial link. * The gateway accepts input on seral which will be sent out on * the RS485 link. * * Wire connections (OPTIONAL): * - Inclusion button should be connected between digital pin 3 and GND * - RX/TX/ERR leds need to be connected between +5V (anode) and digital pin 6/5/4 with resistor 270-330R in a series * * LEDs (OPTIONAL): * - RX (green) - blink fast on radio message received.

  @tekka Had tried that before , so I was looking for the solution not by changing IDE but why did it fail, So I loaded Windows 10 Pro Workstation on a new drive booted from that drive and setup windows. Once windows was all configured I then installed exact same IDE and library as before and what do you know it worked just fine. Conclusion it was the OS that stopped Arduino IDE 1.8.4 not the IDE or the MySenors Library, and yes it took more time to trouble but now I know why and I don't have to guess. I have found that Windows 10 is very protective of it's self and once system becomes corrupt in the smallest of ways you can bet before long you will see in other applications things starting to "not work" like they use to when you first installed the OS. If I had the time or desire I would switch over to Linux but I am to heavily invested in Windows with my machines and software for now and have been using Windows ever since Windows 3.0 Hope this might help others that might be having similar problems for the MySensors library's to fail when they should not be failing.So check out every avenue before blaming MySensors or the IDE Thanks for reading my post Bob

If you wanted to play it safe (aka defensive programming), you could use your booster to charge a capacitor that's large enough to provide interim power, turn off the booster prior to doing your radio communications, and then turn the booster on again when you're done with tx/rx. That would effectively remove your booster from the equation as an interference source. Also, some boosters have a pass-through, so you can use your regular battery voltage for as long as it's high enough, and then when it no longer is, enable your booster, if that's what you want to do. Here's an example of one: https://www.openhardware.io/view/285/33v-Boost-Converter-with-Pass-Through For instance, CR2032's can have quite a voltage dip after volunteering some current, so this would be one way to keep wringing a useful voltage out of such a battery after its voltage may have temporarily dropped too low. Some of the ARM MCU chips include boost converters that can boost from as little as 0.5v....

  Actually I have to disagree with @rejoe2 about: Will my network work without controller (only gateway + nodes)? With an Ethernet gateway it is entirely possible. One more thing. If you are interested in building RS485 network, maybe you should have a look at my project. Earlier today I created a post about it on this forum. Here it is

  Hello first of all, excuse me for my english, i'm french. I try to use the sketch with the 10 relays, but nothing works on the buttons. I tried with several resistance values using "analogread" to read the real values, but when I enter the values in the table nothing happens at the relay levels. P.S: the relays work with jeedom. can you give me the procedure to follow to properly "configure" the sketch? cordially

  @amasterp1322 You will need to provide much more data I'm affraid. Where in the world is 'the project'? What type of sensors have you chosen or do you need help with this too? What are you measuring the moisture of and to what level of accuracy do the measurements need to be? What kind of distance is there between the sensors, relay, power source? Does everything have to be water resistant or waterproof? Is this an indoor or outdoor project? How are the sensors going to send data? What are the sensors sending the data to? What relay is involved and how was it specified? What is the relay activating and will you be following the electrical codes for your country/area? I suspect this is a greenhouse watering system, but you haven't actually defined the project so maybe you can give it some more thought to help us help you.

  From what I understood, the solution from @tmandel was meant to revoke sleep based on incoming message. I needed to delay sleep due to messages waiting in the outgoing queue. At the end, I just got my fork of MySensors and added additional extern callback to MySensorsCore.cpp/_sleep just after the pre-sleep wait(MY_SMART_SLEEP_WAIT_DURATION_MS). The callback is then implemented in my source, where I check whether the oubound queue is empty. If not, MY_SLEEP_NOT_POSSIBLE is returned and the queue is flushed immediately in the next loop(). It may be crude but... hey, it keeps my flowers watered. Many thanks for the advice and the direction provided!

  Just a thought. I would personally go for one child ID/sensor. "There is uncollected mail" indicator. Set it to true when small door is tripped, and set to false when big door in open.

  https://github.com/MajenkoLibraries/ICSC Examples are there too. ( MySensors uses this code for 485 transport layer too ) Or another very simple example: https://circuitdigest.com/microcontroller-projects/rs485-serial-communication-between-arduino-uno-and-arduino-nano

  power consumption wise resistor-less method and running directly from LiFePo4(rechargeable 2.8-3.6V) or LiSoCl(3.6v non rechargeable) battery is best. Unless you remove regulator and USB/rs232 chip it's all wasting your time. @mfalkvidd said in Which battery measurement to use?: But if you get a "good" booster, the battery life will be more limited by the self-discharge of the battery than by the power usage of the node. Same goes for the non-boosted variant. Depending on battery chemistry, LiSoCl will last 15 years. with carefully designed MyS node you can get 10 years on single AA LiSoCL battery. Something like power meter pulse counter transmitting once every kWh.

  I've manualy removed the call for watchdog reset from function void doYield(void) and I can see my user watchdog timer working again... This will probably affect some deep sleep and waking processes - that I do not care about in my cases... I used RadioHead library before, which is much more library in sense of composable part and I was very happy with it's long term stability... Now I'm trying MySensors and it's quite unstable comparing to RadioHead... If it had software signing, I'd definitely use RadioHead... Let's see if enabling user WDT will fix the unstabilities...

  Hi, i have similar problem with domoticz and mysensors. Firstly, i can't get current dim level from domoticz on startup. Secondly if i start arduino and controll it over domoticz only, dimming and on/off works. If i turn the rotary knob, domoticz commands won't work. In serial monitor i see that new dim value has been received: Serial.print("Fading level: "); Serial.println(dimValue); but output doesn't change. If i turn knob on rotary, value in domoticz changes. I removed eeprom writes and rotary button. Only dims to off/on or domoticz commands off/on.

  @bc123 Read and understand the posting rules here. I know this is your first post here... but how is that? How did you find your last 'programmer' for mys if not here> Just curious. Post code in code tags (as per the instructions) - i.e. choose the </> in the options above. Then paste 'your' code (if the original code is under any NDS or copyright then you do so at your own risk). Pictures of the wiring, as installed and wiring diagrams. Oh, and a full spec of what you expect and how it is all supposed to work would be a good start. Seasons greetings all the same to you.! I'm off to drink more alcohol than any sane person would.... - Apparently it is 'that' time of year.

  @apl2017 most MySensors nodes are battery-powered and sleep to conserve power, which means they aren't "on". With that said, most examples transmit on regular intervals. The interval is configurable, so you can set it to a short interval if you are not concerned with battery consumption.

  If you compile Mysensors for Raspberry Pi as an ethernet gateway, you will be able to send commands to a socket on an IP of your Raspberry. You can use netcat command, or a python script, as described here: https://forum.mysensors.org/post/88439 This way, you won't need any controller software, if you are not planning anything big.
