  @skywatch The naughty step is my second home... I understand what you're getting at, played with radio and antennae most of my life although only into the uhf bands, as I found out to my surprise, many have on this forum... But the problem remains as @Nca78 pointed out the range for a given input power, dodging or penetrating obstacles in the modern domestic environment with composite structures and steelwork becomes progressively more problematic with higher frequencies, it is as you noted yourself rather pernickity. At my age, pulling my hair out is not an option hence my choice of uhf for the system here, lower power input, longer battery life, keep what hair there is...

  My recollection of MOV specifications is the are often rated for AC operation I.e. In the US we might use a 130Vac MOV. While others are rated for DC operation. For most folks it is probably wise to follow those ratings. If you are really into MOV.s then you look to the curves. I do not mean to imply that AC rated MOVs a different from DC rated MOVs, they are both physically the same parts, its just how the catalog presents the specifications.

  @robert the NUMBER_OF_RELAYS is already defined in your sketch, just use as pasted. I use OpenHAB so i just tried to install Dormotiz and was supreised that it took less than a an hour to install and get working with the relays. (Most of that time was trying to get them to shown up on the dashboard) Dormotiz is communication fine with my node and i can switch on and off the relays from the Dashboard In the sort time i have checked i do see that the Last Seen time only changes when i change the state of the relay. So your program that you posted works for me with both my normal OpenHAB and the new test Domoticz. I think that i may be miss understanding your actual problem.

  @bjacobse Yes, you are absolutely right, and that password only is required when you trig the device inside controller. I mean, if you click the icon in controller for that device and device is protected, it asks for password. And if you also use HTTP API, you need to provide password as well. So if you want to trig the device from other Mysensor node (my case), it does not know about the protection and you can directly send the message to trig the device on or off.

  I use a reed switch on my gates - when they are in contact the gate is closed. You could put more at the open points for fully open but I only cared about closed or not. I assumed for 20 secs after they started opening they are opening else they are open. When I close the gate I assume closing until the reed switch shows closed - of course opening the gate during closing will reopen (I also have IR to detect car so gate will not close onto a car).

  Another way to get multiple frequencies is to use network based gateways. Check out these projects: https://www.openhardware.io/view/457/Easy-Peasy-Amplified-MySensors-Serial-Gateway https://www.openhardware.io/view/394/Minimalist-LoRa-Ra-01-Shield-for-WeMos-D1-Mini https://www.openhardware.io/view/390/Minimalist-RFM69HCW-Shield-for-Wemos-D1-Mini I have serial gateways for NRF24 and RFM 69, but added a LoRa RA-01 Wemos-D1-Mini with no issues.

  @skywatch @mfalkvidd Thank you for your comments. I am using Moteino R4 and RFM69 connected to hardware SPI pins. I tried the same pin with softSPI, but I could not get success. Now I have altered the ADE7763 Arduino library to update SPI settings on every call. And added code to update the only flag on ADE7763 interrupt(like we have in RFM69_new library). Seems all look somewhat ok. I think for RFM69 we use a default clock speed. for ADE7763: SPI_CLOCK_DIV4 Are you using pull up resistors on the CS lines to each device - that might be worth a try too.... Yes, I have

  @mfalkvidd Thanks! That is almost the same as my readings. @scalz I have been working few years with ZigBee modules from TI (CC2530). I had dozens of different setups with integrated and also external antenna. RF values was not "just datasheet numbers", if there was written 20dBm output, it was there. But fully agree, that here is the problem mainly caused by non-optimized antenna... So there is a huge space to increase the range of modules... And one more update, whch I think can be very important for all others. My setup is running on OpenHab2 installed on OrangePi Zero with SerialGateway connected over UART. Just now I had realised, that OrangePi makes huge RF noise. If I will run setup normally, receiving sensitivity is very poor. Once I start setup without SD card inside of the system (OrangePi will not start up), Arduino gateway is receiving perfectly. I have just putted SerialGateway to the 50cm long cables, far from OrangePi and usable range is more than twice longer than before. Thans for your time guys. Appreciated.

  High sensitivity: down to -148 dBm. From the datasheet. There probably needs to be some margin, but my experience with Sigfox shows that -130 is quite reliable. After that, packets start go missing. I would guess LoRa is similar.

  Hi @mfalkvidd, Problem is, when your code can't compile because you are one (or several) bytes short of ram, nothing else matters. As to readability, I assume you know about that rarely used compiler feature called 'comments'? I hear they use zero Arduino RAM and even less ROM memory. . Ok, I'm just being cheeky, so don't flame me, it just seemed a good opportunity for a reminder to everybody. Point being we are all guilty of not using enough comments in our code. You said you are worried about readability and maintainability - it's just like code backups, it's a problem only because we only worry about them 'after' a drive crash, or in the case of comments, two years later when we are trying to remember what the hell this weird code does.. THE REALITY: If we are really worried, we would add liberal comments and do regular backups - otherwise I say we're not really 'that' worried. Cheers, Paul

  @pierrot10 1 mm of rain over 1 square meter is 1 liter of water. Correct! One liter makes 358 tips so one tip is then 2,7932 milliliters that is correct. But rainfall mm/hr is 2,7932 * nbr of tips only if the area of the funnel is 1 square meter. Your funnel is only 55 square centimeters so you will only collect 55/10000 of the rain that falls on the whole square meter. The example you are using at the top of your post does not have the size of the funnel anywhere in the code.

  I'm using miceuz's Chirp I2C sensors here. Found it to be much more reliable and consistent than the cheap analogue sensors, particularly dealing with large outdoor temperature variations. The "rugged" model works a charm. I'm getting about 12 months off 2x AAA batteries, using some aggressive sleeping. As you've surmised, hook up the power in line to a Digital Out so you're not constantly powering the sensor when your board is asleep. You'll need to wait() about 200ms for the board to wake up after supplying power, and take a few dummy readings each time you wake it for it to stabilise.

  There is no need to change sketch version. That field is for information only. I don't think controllers support removing anything automatically. Maybe if they have an external api. I'm unable to find anything like that in the Domoticz api: http://www.domoticz.com/wiki/Domoticz_API/JSON_URL's But since it is possible to delete stuff from the Domoticz web UI, maybe you can just check what a delete request looks like?

  @monte said in easy FPGA'S: I have same questions as some guys in the comment section of that video. I know what FPGA is, but I can't understand what is the use scenario for those who are using MCU's for their projects. And as we are on mysensors forum, maybe you have in mind some application for FPGA to our common needs? I can't imagine myself starting to learn verilog right now, but I hear about it from all around so I might consider learning it in near future, but I can't make myself learn stuff unless I see some interesting application of new knowledge. Thanks for bringing this up. I'll concede the point, because after looking into it a bit more, I think you're probably right. I mean, the newer ARM chips consume less than 100na in sleep mode and seem generally quite power efficient: https://www.microchip.com/design-centers/32-bit/sam-32-bit-mcus/sam-l-mcus

  As promised this is my wiring and code, hope this help people out First the wiring.

  Does adding ack to messages help trigger any failures if something can't deliver? ... well that didn't make much sense. So lets say i have 2 repeaters on my network. i have a sensor that wakes up to report info. it normally goes to repeater1 -> gateway but repeater1 is acting up. Could you tell it to wait for an ack? after X amount of time with no ack would it trigger to find a new parent?

  @hard-shovel Thanks for the response. The volume control is motorised so no need to 'remember' where it is as it is possible to manually change it and there is no feedback that could be used to determine changes. The remote control requires you to hold the volume buttons (+&-) down until desired volume level is achieved so I suppose I could start repeating the IRSend code from the node if one valid volune command is received. The first time the node gets a valid volume command it just repeates the send over and over until it gets another identical command which stops the loop. I'll think more about it and also see if the controller has something that might be suitable. Edit - Why not just start the volume repeating the code to go in whatever direction you want at a suitable speed and add a volume 'Stop' button - that would be easier! - I think I'll try that at the weekend...... Thanks again, I can finally start hiding all the remotes cluttering up the place!

So there is likely more than one solution to this problem. Also, I have used 'for' loops as well and wonder how this affects memory and battery drain? Thanks

  I made heating as simply as possible - with good house insulation ( 20cm foam PVC for walls and 40 cm for roof ). I am using el. floor heating ( cables ) on both floors + fireplace like backup for unpredicable situations and for fun. I know, that heating cost me 2 or 3 times more than with heatpump, but consuption is low and investition was really very low too. ( cca 600 euros all heating cables and I made all work myself ) Regulation in this time ( and last winter ) by cheap Wemos with relay board and ESPeasy firmware on it in each room. It can regulate room or floor temperature ( I am using floor temperature regulation ) . Mode of operation and temperature setting are made from Domoticz, but regulation is made by Wemos itself - not running Domoticz needed. Temperatures and energy consumption are reported back to Domoticz. It was very funny two weekends project. One weekend familiarization with ESPeasy and next weekend regulator and Domoticz integration making. But it is not final stage, because ESP is very energy "hungry" and 4 lines of my UTP cable is not enough for cca 7 Wemos with relays on each part of bus. And I do not want wi-fi using for my sensors. But I need quick solution and it was.

  @alowhum Zigbee being "a standard" is not an advantage at all. As you put it, it is indeed not true at all. Using "a standard" in the meaning of "a formal definition of one of the piece of your puzzle" is only an advantage when you want to potentially replace that piece by a piece produced by another manufacturer and still get that talking to the rest of the puzzle. You should also consider that there are two kind of standards : "committee" standards, where experts provide a formal document and people pay to adopt that way of doing things, and "de facto" standard, where there are enough users that do things the same way (or buy the same thing) that it guarantees sufficient resiliency. For example, USB is a committee standard (but if you use A, micro, mini etc. you have to adapt), Arduino Uno is a de facto standard (and there as well, you can choose between Uno or micro, etc.), and its success made possible the clones costing a few bucks.

  You can buy on LCSC also, I bought a bunch of components there together with PCB (at jlcpcb, same company), price is not as low as AliExpress (and some US components are even more expensive than legit sellers like Arrows) but they have a lot of things at "Chinese price" that you can get all at once. I found a few things like connectors, battery protection IC etc that are hard to find or expensive on Ali/Ebay.

  Thanks. Unfortunately, none of those resources had the part identifiers for the parts that I have. So, lesson learned: I'll create my own ID catalog every time I buy a receive a new part. That way, if need be, I can identify it later.

  @akya the number of times you can read a DHT11 in a given time period isn't limited. You can read as fast as you want. The limit widely mentioned (at various rates of around once every 2 seconds) has to do with the heating effect of turning on current to the temperature sensitive resistor to take a reading. Someone tested and noticed that reading at high speed caused a slightly elevated temperature reading. You can test for yourself and see at what read rate you notice an increase, or just limit to once every 2 seconds or less.

  @รอเร-อ Then I suggest you please re-READ, and as I suggested, Google, as Abraham Lincoln once said, "Never believe absolutely everything you read on the Internet". The 5v is irrelevant other than the threshold voltage which registers as a HIGH to it's I2C control. The 3v3 as Master dictates the HIGH as a factor of it's VCC on the I2C bus. THAT is the issue. As Vcc is never absolutely accurate you may strike lucky on a 3v3, there again you might not, your choice... EDIT - To avoid any confusion, what I am referring to here is conventional I2C system. The input HIGH for a 5v is say 0.7 of Vcc, so 3.5v is required on the 5v I2C line to register as a HIGH. Even if a 3.3v Arduino were to put full Vcc on the I2C line it is just below the threshold for the 5v device. That is where the factor I referred to comes in, and I read elsewhere it can be 0.6 but cannot recall which device that referred to. Hopefully that clarifies what I was referring to.

  Thank you for the idea. I try and I will do a report. But is there a way to start the sketch after a delay even if the gateway does not find the broker. I understand that this is not very interesting .... except for my library. With a node, it is possible to start the sketch after a delay with the parameter MY_TRANSPORT_WAIT_READY_MS. Thank you.

  @mfalkvidd Unfortunately, the "Enable In-Topic Searching" feature is what generates the start of "in:topic-4803 soft_hmac_key" and nothing else. It does find the first occurrence but doesn't have a way to search after the first. I learned that I can just prefix "in:topic-####" to my search and then I don't have to make the forum grab the <ctrl> f key in my browser. @the person who edited the "Posts per Page" restriction of 20, a huge giant Thank You!! 100 posts per page is a great improvement over 20. I was about to request this but saw it was done when I went to get the exact wording. This giant topic being 10 pages is bearable. (and probably doesn't use a ton of javascript which was blocking local caching so probably saves a ton of bandwidth for your servers...) P.S. my original problem is solved too, the forum is so useful!

  @alexsh1 Much the same principal as my 5v/3v solution for the 5v ultrasonic, only here I used a latching relay leaving the 3v Arduino on sleep power consumption. An interesting device however, with a low standby and effectively a timer function, it has many possibilities. Where this original project has been skewed is unfortunate, the selected devices compel the dual voltage solution, whereas an alternative strategy removes the need for it completely. Although pulses and switches can be regarded as "old" technology, they can still be highly effective for battery powered applications where energy conservation is critical..

  Arduino IDE can only program chip, not read its program memory. But you can use AVRDUDE ( maybe with some GUI ) for reading program memory from your chip. And in your program sketch define some string to identify version. It can be read hex output of program memory then.

  @gohan Nope, hourly measurement is quite sufficient. I had bought two of these with onboard RTC to pass time control to the DS3231M and let the Nodes sleep, at the time it was purportedly energy advantageous. I'm aware I could have used a non-RTC version and a sleep time, although have yet to succesfully make sleep for an hour for some reason, yet 30 minutes is no problem. Just puzzled how it should be deployed, hence the query..

  Thought I'd share a couple cool things I've learned recently. One is that meshmixer offers treelike supports, which is pretty cool, and it's free: You can import your model and just add the supports without using the rest of meshmixer, if that's all you want. That's how I plan to use it. The other is that if you want to print faster, but with good print quality, you should definitely look into linear advance. How to use Linear Advance in Marlin – 10:58— Teaching Tech Anyone else learned anything cool lately?

  @zboblamont After a lot of headscratching I solved part of this puzzle and feeling a little stupid. Nothing to do with Library conflicts, both Wire and softwareSerial work as they are supposed to, the level converter works perfectly, it was a combination of sketch issues and the manner in which sleep was invoked on both Master and Slave, as well as a problem ultrasonic board. 1 - The DYP-ME007Y I could only ever get to read on a Russian developed sketch using softwareSerial. Although I got the reading once, the Slave was locked in an endless loop in the background, never going to sleep or giving the battery reading. By doing the ADC battery measurement first at least I got both readings, but with the Slave running endlessly even with the ultrasonic board shut down, it was killing the batteries. So I gave up on that one and switched to the second tank which uses time of flight calculation, readily incorporated as a function. This time I incorporated LED flashes so I could see what WAS and was NOT happening. 2 - The JSN-SR04T-2.0 Slave went to almost immediately per Gammon's sleeping Slave routine, would waken when prodded, but would not return a battery reading. The problem lay in Gammon's preparations prior to sleeping the Slave, where he turns off the ADC, but it remained off when awake. Commenting out the ADC shutdown at least solved that issue for now, at least the Slave gave the required readings and went to sleep, but... it never started again. 3 - The Master was going to sleep but never wakened on the onboard RTC alarm set to Int1. Switching to a straight Sleep period did not work either, until it finally it dawned that the Wire service may be interfering. Only when Wire was shut down and re-invoked after wakeup did both Master and Slave sleep and awaken as intended. Left it running overnight, and it has been consistently reporting every 30 minutes, so will look again today at getting the DS3231M to work properly on the Master and read how to restart the ADC on the Slave. Frustrating as a relative amateur, but lessons learned. If there is no function to interrogate the DYP ultrasonic, may just order another device from China and hope it proves simpler, cheap enough even if it takes a month...

  @flyyboyy A1: From the datasheet: 3.3V operation with 5V I/O signal tolerance A2: I think so A3: If I understand the library code correctly, the new RFM69 driver supports softspi but the old does not. Add this to your sketch (before #include MySensors.h) for both the gateway sketch and the node sketch. #define MY_RFM69_NEW_DRIVER A4: If you don't know you need it, leave it the way it is in the example. This goes for almost everything. A5: Do you mean MY_CONTROLLER_IP_ADDRESS? This is only used for client mode. I think OpenHab can use server mode. A6: Just leave the default A7: When you want to use local sensors, you'll hopefully know why There is absolutely no need for local sensors, but MySensors supports local sensors for those who want them. A8: Correct.

  @nca78 said in Fewer home automation postings? What's behind it?: The only problem I see is it's based on an atmega setup which will probably soon be deprecated for MySensors. Yes that is an issue. For now I'm trying to keep the sketches so simple that the simple signing and encryption feature will still work. I read that in MySensors 2.3 a goal was to make the encryption and signing features use less ram, so there might still be some life left in the Nano I also found an STM32 board that has a NRF socket built in. But that has to be manually soldered, and it also make sensors less easy to connect (fewer GND and VCC pins).

  @alexsh1 signing fits fine on atmega328p. Just comment out any calls to your libraries and the linker will garbage collect any code drawn in by them. Once you confirm your security is operational, disable the debug prints alltogether and add your library calls. Of course, if you have space issues even then, there is not much to do but optimize the code.

  I really like mysensors.org, but I've always had difficulties with the site organization. In my opinion, is not intuitive at all, although it has a great and appealing theme. Well, maybe it shouldn't, but this sets me back when trying to build anything... I know this excellent initiative for a couple of years now, and from time to time I try to do something but I end up de-motivated because it takes too long to find simple answers/solutions. At the moment, I have nothing built although I have all the equipment I need, including SenserBenders. Yes, frustrating like r-nox commented 2 years ago. Anyway, my point is: For the ones looking for a library that makes this DHT sketch work, mysensors have compiled a set of libraries that include this DHT.h and many others. Just go to https://www.mysensors.org/about/arduino#optional---install-external-mysensors-examples (yes, the name is not intuitive, maybe the keyword library would make it more obvious?), or jump directly to here and follow the standard library instructions. It took me two hours to find this, hope it saves time for future followers of mysensors like myself. Good luck!

  @soloam OK, so in the end this seems to be a problem related to that particular controller software. Imo it would be better to address this issue by enhancing the controller software towards a more constant handling of added infos from user side like renaming devices rather than using the limited space on the mcu to store info not needed by other controllers.

  @gohan What do you mean? The rPi or the Esp? For the rPi I first used a NRF24 pa lna getting power from the 5v line with a voltage regulator (ams1117 based) Then I thought could be problems with this radio or supply and ditched it for a normal NRF24. With identical behavior. Sometimes works for a week or a couple of them or I have to restart the whole Pi several times a day only for being able to go out of home. When I first implemented the rPiGw worked for weeks. Then the problem appeared. then vanished and was working for months until some point that became worse. I even thought that my wifi hotspot could be dying and changed it for a unify-pro (nice gadget) I live in a house far from others, so wifi interference seems not an issue. I run the Pi from a readonly sd for boot partition and then uses an usb drive for the system+controller. logs on tmpfs. I was fastly implementing it in my home, but as this problems arose, I only have the power monitor node, the garaje door node and a doorbell that is offline because suspiciously started to eat batteries two months ago. I'm in Domoticz beta. For the esp gw it's just a nodemcu board on a breadboard paired to a normal nrf24. Edit: Ups! mysensors versions are all 2.2.0. The arduinos are all 3v3 8mhz boards and one 5v (power)

  Perhaps using a different microcontroller could also be an option? I'm personally not to deep in these things, so this might be completely wrong, but at first sight I'd try to get this working with a STM32F1 board. Seems that using them in conjunction with direct access to the ADC might speed up things, see http://wiki.stm32duino.com/index.php?title=API#Reading_from_.26_Writing_to_pins as a short reference. And using MySensors with STM32F1 seems to be used by several users here.

  I did some development but it has been "on ice" for over a year. The idea was to offer something running in the "cloud" for quick testing and sharing sensor readings with friends and family. But (as always) it quickly grow out of proportion (storing historic data, dashboards, mail triggers etc) and I realised other projects does this much better. I.e. a hosted NodeRED would do the trick (e.g. https://fred.sensetecnic.com/). Another issue would also be how to handle the hosting cost for the service (which would require a few more cpu cycles and storage than the current site). Not sure what will happen with the code, it was pretty tied to the main site with users etc. Maybe I will pick up the work some rainy day.

  So I did more digging and I found the AS3933 IC. They have reference designs/demo boards (very expensive!). Still not sure about range, but it looks like this is possible.

  I have a similar situation: my house had manually operated roller shutters, where you had to keep the button pressed to open or close them. Importantly when the end stop is reached, the motor is not powered in the moving direction anymore (probably some integrated reed contact or something). If this is the case for you, my solution will work well: Just make a normal arduino relay (1 for every direction) and calibrate them with a timer. Then just make sure that you add some time for the opening direction (a few seconds), it will make sure that for every cycle any drift is compensated. This even worked for me when I had to reset the system with the rollers at a certain percentage => just move up and down a few times and it's ok again. In my system I have implemented the manual switches (which used to switch the 220V by connecting them with the 5V node source and switching dedicated input pins on the arduino. I have two nodes, one with 3 roller shutters and one with 1 shutter and 1 awning. (I think on the 3 up/down variant, there were not enough input pins for manual input, so I had all bound to one up-down switch). Here's my code (it has become somewhat messy, and if I remember correctly I changed from 100% open to 100% closed mode when changing from home assistant to openhab2): /** 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.

Or "overshoot" opening by a margin to make sure 100% corresponds to fully open? (yes: home assistant takes % open, not % closed) The sketch supports multiple blinds, i.e. multiple relays connected to the arduino. There are two relays per blind, for up/down respectively Also, additional pins are read for a push-button, to manually give the up or down signal (will start/stop moving one or covers simultaneously, based on btcidmap[]) To avoid the relays coils from being powered in normal operation, and most relays are active low, high/low has been reversed (so high unless activated) (better buy active high relays!)

  @tbowmo I ended up building a swr circuit and just send a 433mhz signal . I know 433MHZ!!?? It was a small transmitter I have laying around Gives me a real nice return single with an antenna on line and almost nothing with no antenna. Now I have to turn the return signal I can control. Going to use the Arduino to analog read the signal and give my a digital output. This gives me the control points I need. I can also use an external Analog to Digital convertor like the PCF 8591 but first going to use the Arduino to do the A/D conversion. Thanks for your help Ed NW4K 73's

  Mysensors has a "savestate" function that can be used to save variables in eeprom without too much hassle, but in your case it since it is a mains powered node you could just report every pulse and have the controller save the data and when node boots it will just asks Domoticz the last pulse count (look at energy pulse meter example in library) but I think that will work only if using mqtt gateway as for the ethernet it will just miss the retrival of the pulse count because the controller takes some time to connect to the ethernet GW. As an alternative there are other solutions like ESPEasy that have already some built in funtions easy to use without need to do lot of coding.

  First attempt playing with the logo. I did a manual filament change from yellow to blue. Didn't have any black PLA, only ABS, otherwise I would have used black. This is more of a lithophane style which didn't do the best, but is still okay. I want to try to figure this out using paths in inkscape and exporting them to OpenSCAD. Having some trouble with that though. I'll figure it out in time. The picture is next to a soda can so you can get an idea of the size.

  @ricorico94 From the NRF24 datasheet: https://www.sparkfun.com/datasheets/Components/SMD/nRF24L01Pluss_Preliminary_Product_Specification_v1_0.pdf So, you should probably choose address a bit careful. To change base address just add a define in your sketch like this (before including MySensors.h): #define MY_RF24_BASE_RADIO_ID 0x00,0xFC,0xE1,0xA8,0xA8

  Very simple solution, but I just put up a single flow (called watchdog of course) that subscribes to "hart beat" and value topics of items I am watching (in my case via openhab, but principle is the same for vanilla mqtt) and then have a "timeout node" for each item. Timeout node triggers if no message comes in in a predefined period (per item, some send data every few minutes, some every few hours) But each arduino node has defined hart-beat interval In my case all timeouts go to a function that formats a message in format "<itemname> not seen in <timeframe>" and that is logged and sent to an email once a day. But you can as well put it into a dashboard as Yveaux showed. I also like use of subflows whenever possible, but in my case all is happening on one flow and in two nodes, one that connects to mqtt hearbeat and one node that triggers if no data comes in (sorry I forgot the name, but it is a default node-red node)

  @mfalkvidd Thx for the "quick and dirty" way. This at least is a starting point, but most things around that seem really to be hard coded (MySensorsCore.h: L77: GW Address is 0 is the point where the getNodeId() finally leads to). But if that really works there might be a way to wrap around that - but indeed this seems to be quite complicated. And indeed, you are right that having multiple nRF-GW's was possible ever since MySensors existed.

  GW to node communication is not affected by Serial / MQTT / Ethernet interface with controller. With ethernet and MQTT you could actually connect more controllers to the same gateway, even on different computers. You can also have gateway running as a service on the RPI with radio directly on the GPIO and you can connect to is from wherever you have IP communication to the RPI (if you use the ethernet) or the MQTT broker (that could also be on another network)

  Ive designed a NRF based mysensor remote with 14 keys, I want to use pin 2 for one of the key. Currently all pin work properly for key but pin 2 does not recognise instead it creates some disturbance in transmission. what i receive on destination node is unexpected. Is it possible to disable use of pin 2 . it looks like mysenso uses pin 2 for some internal use.

  @dakipro see here for a mapping of wifi and nrf24 channels: https://forum.mysensors.org/topic/4721/nrf-frequency-and-channels/5 NRF24 Channels 2..96 overlap with wifi. I personally would stay away from the high nrf24 channels (110+) as I've seen troublesome performance with clones. Channel 100 performs well at my place.

  Hello, no there is no minimum frequency but for a serial gateway I would keep it at 16MHz to avoid any missed messages. It also allows a high baud rate on the serial connection. For battery powered nodes I use them mostly at 1MHz, there's not much interest going lower as you get no more gain in allowed voltage and not any significant gain in power consumption while the processing time increases.

  @johnrob said in Why I quit using MySensors for actuators: Hi, I know I'm a little late to this thread. I'm just starting with MySensors and am learning by reading the posts. Currently I am waiting for hardware for my 1st gateway so I am not encumbered by details. I notice in all the reported cases the "problem" node is AC powered, while many of the "good" sensor nodes are battery powered. Could this be significant? It would be interesting if someone with a "problem" actuator node could put a battery operated sensor node in the same area. Hello, the problem is an actuator node has to listen to the radio constantly and can't sleep, so it can't last long on batteries...

  @mfalkvidd Serial input will come from a windows based PC. Probably the same as the one that acts as the datalogger. The actuator could be any actuator-node. To give you some more info: I have some lights in my shed (mancave actually.... ) that should turn on when pressing a button, somewhere nearby, i.e. near the door. This button is connected to a node that sends the command to the actuator node. setdestination will play a role in this node. There's also an automation scheme to turn on (and more important: off) the lights. As the shed is quite far away it is very handy to turn off the lights when I have returned to my home and forgotten to turn of the lights (for whatever reason). For this purpose I will use this specific node. Once I manage to controll the lights in the shed, I will be able to controll some more things around.

  I've added LED strips under my stair threads for night use. I've learned the "Daylight" (most blue / harsh of the white) is the most efficient. It seems to make the "warm" whites some of the brightness is "consumed". My lights are running at ~ 1% on time (153 hz) and work great at night. There are 6 meters of light consuming 0.5 watts (including the AC adapter). The cost of the LED strips is trivial. Look on ebay, you can probable get 2 or 3 different kinds for < $10 total and see which you like best.

  @neverdie The bulk of MySensors nodes run on Atmega328P, with 2k of SRAM they're already quite resource-constrained in some of these sensors.

  That's right @gohan , if you place the "door closed"reed near the floor then only first interrupt should matter, first interrupt should tell you the door is closed. Same for a second reed placed high - the "door open" reed, that would tell you the door is open when interrupted the first time. @McQueen, could be close to you needs ...

  It certainly looks to me like some issue with power supply. Have you added a capacitor close to the power pins of the radio? It's also a good idea to power the radio directly from the power supply instead of through the arduino supply which is very limited.

  @signal15 that depends on whether you by "turn on" mean require signed messages, if you run the official release or beta release and if you have the relaxed security flag enabled. The documentation describes all possible scenarios. Just make sure you read the version that correspond to the version you use (beta or release).

  Other thoughts: you could have a watchdog which activates a backup gateway if the first one becomes unresponsive. It would make for an interesting project. Probably not too difficult either.

  @mljbr4 You can change it on the fly by calling RF24_setChannel( c ); But, that's probably not going to work in your situation.... If you change it in before() it will be overwritten by the MySensors stack, if you do it in setup() you're already too late... What you could try is define a variable holding the channel, and make sure this gets set to the right value before MySensors starts, e.g.: uint8_t channel = 76; // default #define MY_RF24_CHANNEL (channel) #include <MySensors.h> void before() { channel = 90; // debug channel }

  Wow, the comments are so old. Hope I didn't bother you guys. Now, I think it would be much better for us to get ourselves an automatic feeder. It would be much more convenient for us to feed our cats this way. Not to mention, you can control the diet and amount of food intake. If your cats have diabetes or similar conditions, getting an automatic feeder will help to improve their health a lot. You check all the important -Removed by moderator- before buying it too. Cheers.

  The people that know me well say I'm one of the "need to see to believe" guys. Therefore I decided to get my SDR device out and install it on my PC. I then looked at the area around the 868MHz frequency. I then launched a fw update on one of my nodes, and waited for some of the zwave nodes to talk to the controller. This capture shows how the rfm69 module is talking at the 868MHz (center red band), while a zwave device send some short bursts of data at 868.4MHz. The two red areas are quite well separated so it doesn't really look like they could interfere. I repeated the test several times and found that some zwave devices seem to be not perfectly tuned to 868.4MHz, and were transmitting at more like 868.35MHz. Even in this case, there are no signs of interference. I also took the opportunity to take a look at the 915MHz freq. In Spain this band is not free and happens to be reserved for the 4g data cell communication. In my area this band seems to be really clear, so I guess the cellular antennas are not using them. However, it's not an option if you want to follow the regulations.

  @wallyllama Nice answer - thanks very much. I'm going to go with a central power distribution point and send out 12v to any nodes that need powering. Each node will have a buck and drop whatever voltage they receive by that point, down to 5v. This way I avoid any voltage drop issues that could occur. It also gives me a single & scalable power source location and nodes close to their activity & still fulfilling their mesh roles and responsibilities! I like the @petewill setup, but will probably establish it using something like these: https://www.aliexpress.com/item/Free-shipping-1pcs-9-road-output-switching-power-supply-wiring-board-current-shunt-board-wit-fuse/693330771.html I was also thinking of going one step further with something like: https://www.aliexpress.com/item/9CH-DC-12V-15A-Switching-Power-Supply-With-Box-180W-Monitor-Camera-12V-Power-Transformer/32602759262.html but I'm not sure just how much to trust these? At least with just the first distribution board, I can power it with some old wall-worts initially (appreciate less power capacity). If anyone has anything good to say about the aliexpress switching power supplies, I may still consider. Cheers

  @wallyllama said in A smart home vs an automated home: The trick is to get them to detect you without actively addressing them. If Alexa can detect breathing, or heat or CO2, etc, then it would solve the problem. If you enter a room and do not say anything, then Alexa has no way of identifying WHO you are. Even if the echo could detect breathing, heat, or CO2, you are back to knowing that someone is there, but not who.

  @Steve-Hadley said in Idiot newbie question: f I build a node using another nodemcu Hi @Steve-Hadley as @gohan said In your case (when using esp8266 based boards) your gateways are the nodes at the same time because they connect to the controller by themselves. Just edit your code to accommodate your sensor and you got easily deployable node anywhere where in your wi-fi coverage zone without additional gateways.

  @tekka Tested the new library and both issues seem to be gone now, great job ! I have one more question though During testing I treid to put things difficult for my radios and move them until reception started to be bad. At some point the FOTA process gave up with a FW UPD FAIL message (line 41146 in attached log). So the node gave up and went to sleep. I was expecting it to try again after wake-up, but it didn't (see lines after 43589). 36734 !RFM69:SWR:NACK 36737 RFM69:PTX:NO ADJ 36771 RFM69:SWR:SEND,TO=0,RETRY=5 36966 RFM69:SWR:ACK,FROM=0,SEQ=119,RSSI=-55 36972 RFM69:ATC:ADJ TXL,cR=-55,tR=-80,TXL=12 36976 RFM69:PTX:LEVEL=12 dBm 36978 TSF:MSG:SEND,22-22-0-0,s=255,c=4,t=2,pt=6,l=6,sg=0,ft=0,st=OK:010001002005 36988 OTA:FRQ:FW REQ,T=0001,V=0001,B=0520 36993 RFM69:SWR:SEND,TO=0,RETRY=0 37203 !RFM69:SWR:NACK 37206 RFM69:PTX:LEVEL=13 dBm 37216 RFM69:SWR:SEND,TO=0,RETRY=1 37423 !RFM69:SWR:NACK 37425 RFM69:PTX:NO ADJ 37459 RFM69:SWR:SEND,TO=0,RETRY=2 37666 !RFM69:SWR:NACK 37668 RFM69:PTX:NO ADJ 37679 RFM69:SWR:SEND,TO=0,RETRY=3 37885 !RFM69:SWR:NACK 37888 RFM69:PTX:NO ADJ 37922 RFM69:SWR:SEND,TO=0,RETRY=4 38129 !RFM69:SWR:NACK 38131 RFM69:PTX:NO ADJ 38174 RFM69:SWR:SEND,TO=0,RETRY=5 38313 RFM69:SWR:ACK,FROM=0,SEQ=120,RSSI=-56 38318 RFM69:ATC:ADJ TXL,cR=-56,tR=-80,TXL=12 38322 RFM69:PTX:LEVEL=12 dBm 38326 TSF:MSG:SEND,22-22-0-0,s=255,c=4,t=2,pt=6,l=6,sg=0,ft=0,st=OK:010001002005 38334 OTA:FRQ:FW REQ,T=0001,V=0001,B=0520 38338 RFM69:SWR:SEND,TO=0,RETRY=0 38547 !RFM69:SWR:NACK 38549 RFM69:PTX:LEVEL=13 dBm 38559 RFM69:SWR:SEND,TO=0,RETRY=1 38768 !RFM69:SWR:NACK 38770 RFM69:PTX:NO ADJ 38805 RFM69:SWR:SEND,TO=0,RETRY=2 39012 !RFM69:SWR:NACK 39014 RFM69:PTX:NO ADJ 39024 RFM69:SWR:SEND,TO=0,RETRY=3 39231 !RFM69:SWR:NACK 39233 RFM69:PTX:NO ADJ 39268 RFM69:SWR:SEND,TO=0,RETRY=4 39475 !RFM69:SWR:NACK 39477 RFM69:PTX:NO ADJ 39520 RFM69:SWR:SEND,TO=0,RETRY=5 39702 RFM69:SWR:ACK,FROM=0,SEQ=121,RSSI=-54 39706 RFM69:ATC:ADJ TXL,cR=-54,tR=-80,TXL=12 39712 RFM69:PTX:LEVEL=12 dBm 39714 TSF:MSG:SEND,22-22-0-0,s=255,c=4,t=2,pt=6,l=6,sg=0,ft=0,st=OK:010001002005 39723 OTA:FRQ:FW REQ,T=0001,V=0001,B=0520 39729 RFM69:SWR:SEND,TO=0,RETRY=0 39938 !RFM69:SWR:NACK 39940 RFM69:PTX:LEVEL=13 dBm 39983 RFM69:SWR:SEND,TO=0,RETRY=1 40192 !RFM69:SWR:NACK 40194 RFM69:PTX:NO ADJ 40228 RFM69:SWR:SEND,TO=0,RETRY=2 40435 !RFM69:SWR:NACK 40437 RFM69:PTX:NO ADJ 40480 RFM69:SWR:SEND,TO=0,RETRY=3 40687 !RFM69:SWR:NACK 40689 RFM69:PTX:NO ADJ 40724 RFM69:SWR:SEND,TO=0,RETRY=4 40931 !RFM69:SWR:NACK 40933 RFM69:PTX:NO ADJ 40943 RFM69:SWR:SEND,TO=0,RETRY=5 41125 RFM69:SWR:ACK,FROM=0,SEQ=122,RSSI=-54 41129 RFM69:ATC:ADJ TXL,cR=-54,tR=-80,TXL=12 41134 RFM69:PTX:LEVEL=12 dBm 41138 TSF:MSG:SEND,22-22-0-0,s=255,c=4,t=2,pt=6,l=6,sg=0,ft=0,st=OK:010001002005 41146 !OTA:FRQ:FW UPD FAIL 41299 RFM69:SWR:SEND,TO=0,RETRY=0 41506 !RFM69:SWR:NACK 41508 RFM69:PTX:LEVEL=13 dBm 41519 RFM69:SWR:SEND,TO=0,RETRY=1 41725 !RFM69:SWR:NACK 41728 RFM69:PTX:NO ADJ 41762 RFM69:SWR:SEND,TO=0,RETRY=2 41969 !RFM69:SWR:NACK 41971 RFM69:PTX:NO ADJ 42014 RFM69:SWR:SEND,TO=0,RETRY=3 42221 !RFM69:SWR:NACK 42223 RFM69:PTX:NO ADJ 42258 RFM69:SWR:SEND,TO=0,RETRY=4 42465 !RFM69:SWR:NACK 42467 RFM69:PTX:NO ADJ 42477 RFM69:SWR:SEND,TO=0,RETRY=5 42684 !RFM69:SWR:NACK 42686 RFM69:PTX:NO ADJ 42721 !TSF:MSG:SEND,22-22-0-0,s=1,c=1,t=16,pt=1,l=1,sg=0,ft=0,st=NACK:0 42729 RFM69:SWR:SEND,TO=0,RETRY=0 42950 !RFM69:SWR:NACK 42952 RFM69:PTX:NO ADJ 42995 RFM69:SWR:SEND,TO=0,RETRY=1 43005 RFM69:SWR:ACK,FROM=0,SEQ=124,RSSI=-55 43010 RFM69:ATC:ADJ TXL,cR=-55,tR=-80,TXL=12 43014 RFM69:PTX:LEVEL=12 dBm 43018 TSF:MSG:SEND,22-22-0-0,s=255,c=3,t=0,pt=1,l=1,sg=0,ft=1,st=OK:20 No detection 43026 MCO:SLP:MS=30000,SMS=1,I1=1,M1=1,I2=255,M2=255 43030 RFM69:SWR:SEND,TO=0,RETRY=0 43065 RFM69:SWR:ACK,FROM=0,SEQ=125,RSSI=-56 43069 RFM69:ATC:ADJ TXL,cR=-56,tR=-80,TXL=11 43075 RFM69:PTX:LEVEL=11 dBm 43077 TSF:MSG:SEND,22-22-0-0,s=255,c=3,t=32,pt=5,l=4,sg=0,ft=0,st=OK:500 43585 TSF:TDI:TSL 43587 RFM69:RSL 43589 MCO:SLP:WUP=-1 43591 TSF:TRI:TSB 43593 RFM69:RSB 43595 RFM69:SWR:SEND,TO=0,RETRY=0 43606 RFM69:SWR:ACK,FROM=0,SEQ=126,RSSI=-56 43610 RFM69:ATC:ADJ TXL,cR=-56,tR=-80,TXL=10 43616 RFM69:PTX:LEVEL=10 dBm 43618 TSF:MSG:SEND,22-22-0-0,s=255,c=3,t=33,pt=5,l=4,sg=0,ft=0,st=OK:30000 43778 RFM69:SWR:SEND,TO=0,RETRY=0 43788 RFM69:SWR:ACK,FROM=0,SEQ=127,RSSI=-59 43792 RFM69:ATC:ADJ TXL,cR=-59,tR=-80,TXL=9 43796 RFM69:PTX:LEVEL=9 dBm So when this occurs the only way I can think of to force another update would be update the sketch, refresh the repo in MysController and assign it to the node again. Therefore I wonder if this is intended behaviour and if so, if there is some other way to force an update after a failed one. Thanks.

  @siklosi how do you plan to use it? For a one time calibration or permanently mount it on the sensor? IMHO the voltage calibration of a battery powered sensor (if done at all) can easily be a one time calibration using a multimeter. I don't see the need for an accurate voltage reference...

  @dbemowsk The serial API (=communication between controller and GW) doesn't distinguish between different transport technologies used in a specific GW. So it's not important if a GW is using nRF, RS485, RFM69, none or whatever else as a transceiver.

  @pumpkinpi welcome to the forum! The flowcharts at https://forum.mysensors.org/topic/666/debug-faq-and-how-ask-for-help/ can probably be useful. You are correct that the radio wiring is ok since initialization works. You are incorrect that a few people has had to use a capacitor. Everyone has to. If not, problems will arise. Maybe not right away, sometimes people are just lucky and get the nodes partially working initially. But the nrf24 radios will fail sooner or later without a capacitor. I understand that the instructions on the radio wiring page weren't clear on this so I have adjusted them.

  @NeverDie It looks to be what can be expected after googlin' a bit; e.g. https://openawg.github.io/2016/04/19/first-test-chamber-constructed.html Opening the freezer's door will further disturb things (did it stay closed in both charts?) Were both measurements aquired using the exact same si7021 sensor?

  My thoughts were to do as follows..... In the garage have a sensor>pro-mini>lora to send signal long distance. Then more locally have lora>pro-mini>serial data out to sedond pro-mini2. Then from second pro-mini2 serial data in>pro-mini2>nrf24l01+>gateway. So 2 x pro-mini with a serial connection back-to-back as a relay. But now you have described the application in much more detail I would be tempted to just add a lora gw as it's less bother.

  @madscientist The only limitation that I see is on the avatar, and that limitation is not in pixel size, but file size. For the cover picture, I don't see any limitation.

  Yes, as mentioned earlier in the thread. I think you're right, though, it would be easier and more practical. Then the problem reduces to mostly just a detection issue.

  @Boots33 said in Experiences, problems and questions: @Nca78 have you got a link to the PA/LNA module from CDEByte , they sound interesting. This one : https://www.aliexpress.com/item/E01-ML01DP5-Ebyte-2-4GHz-20dBm-2100m-nRF24L01-SPI-Wireless-transceiver-module/32638720689.html I have one with IPX antenna too, and it works very well with a IPX=>SMA adapter and a SMA antenna outside of the enclosure https://www.aliexpress.com/item/2-4GHz-rf-Wireless-uhf-Module-Power-Amplifier-E01-ML01SP4-Original-SENET-1-8km-2-4g/32806320077.html

  Just for anyone following in the future. Looks like it might have been a dodgy USB cable. All is working well now. Thanks for looking.

  This might not be a perfect answer, but: You may first try to analyse the Power Meter Pulse Sensor. It's quite easy to understand, what it does - despite it uses an interrupt service routine you may not need. This may be helpful to understand how communication between node and controller is organized and timing of data sending for non-sleeping modes can be achieved. You may then just put your code into this basis - just add your parts wrt. measuring and delete the not needed parts (or make them comment first). Some further remarks: There is the rather complex Rain Gauge sketch with a lot of options that may be confusing at first sight. This may already be prepared to do most things you may want to do. In Most cases, it's easier to do the statistics part on controller side and just let the nodes report small "snapshots". So resetting the counter and use an RTC is not necessary... I don't have the link at the moment, but there also exists a small example, how to combine sonsors. I also found this helpful to understand how to convert standard arduino code with MySensors functionality.
