Hardware

I just found out that my gateway is not working great. I made a new one but i don't know why the other is not working good? Solved it, it was not the gateway, it was a repeater node that couldn't pass the messages all the time.

I know about the step-down yes, that's why I'm guessing that the VCC for the radio cannot be used for the sensors as they use 5V (using thoses ) I'm not sure I've understood the part about capacitors. Are you suggesting me to add capacitors for every sensors ? I have thoses, do they fit my needs ? The pro-mini will be powered using this . I hope everything's fine ! regards,

@jeylites Vera does support scene controller also and it is working great in UI5. I have no experience with UI7 but I bet it works.

@bob543 you could probably use rs485 (isolated) for this..

@Mickey No, you need one 100nF on each supply pin. (don't have datasheet at hand, so can't remember how many supply pins there are). Place it as close as possible to the supply pins.

@rvendrame Ever since I removed ACK & true, I have not been having any fails at all. Everything works and I have posted the final sketch in Array Relay Button Actuator as linked below... Hope it comes in handy. Thanks again MYS community! http://forum.mysensors.org/topic/1299/array-relay-button-actuator/12

That was indeed the plan. 2 full batteries in series will start of at 3.0V and if they're empty, the voltage will have dropped to 1.6V But to be fair, I'll be happy if it still works at 1.8V, because that’s the voltage the atmega328 will start to fail.

@pete1450 said: Based on this: http://www.mysensors.org/build/serial_api Example 1 id Node-id 0 Child-id 0 internal message no ack payload is type I_LOG_MESSAGE and your actual payload is "read: 21-20-0 s=0,c=1,t=0,pt=7,l=5:16.7" EDIT: I'm not sure if there is an easier place to get this, but I looked in the code for process where it prints "read" messages and found this to describe the payload. Send is also in there. Mysensor.cpp Line 221-222

I have been using an old(cheap) wall-to-USB power supply. I'll give it a try with a beefier supply and let you know the results I get.

@destos Wow!

@scalz exactly .. synchronization ...

I did some quick coding, combining it with a temperature sensor. It did work for a couple of hours, after that my 9V battery was drained so far that I didn't get any data send from the sensors anymore. Quite likely the IR sensor uses a lot of power while it keeps transmitting IR. Anyhow, my quick and dirty code is: // Example sketch showing how to send in OneWire temperature readings #include <MySensor.h> #include <SPI.h> #include <DallasTemperature.h> #include <OneWire.h> #include <DistanceGP2Y0A21YK.h> #define ONE_WIRE_BUS 3 // Pin where dallase sensor is connected #define MAX_ATTACHED_DS18B20 16 #define CHILD_ID_DISTANCE 25 DistanceGP2Y0A21YK Dist; unsigned long SLEEP_TIME = 500; // Sleep time between reads (in milliseconds) OneWire oneWire(ONE_WIRE_BUS); DallasTemperature sensors(&oneWire); MySensor gw; float lastTemperature[MAX_ATTACHED_DS18B20]; int numSensors=0; boolean receivedConfig = false; boolean metric = true; int distance; int lastDistance=0; int loopCounter=0; int loopsBetweenTemp = 60; // Initialize temperature message MyMessage msg(0,V_TEMP); MyMessage msgdist(CHILD_ID_DISTANCE,V_DISTANCE); void setup() { // Startup OneWire sensors.begin(); Dist.begin(0); // Startup and initialize MySensors library. Set callback for incoming messages. gw.begin(); // Send the sketch version information to the gateway and Controller gw.sendSketchInfo("Temperature and Distance Sensor", "1.0"); gw.present(CHILD_ID_DISTANCE,S_DISTANCE); // Fetch the number of attached temperature sensors numSensors = sensors.getDeviceCount(); // Present all sensors to controller for (int i=0; i<numSensors && i<MAX_ATTACHED_DS18B20; i++) { gw.present(i, S_TEMP); } } void loop() { // Process incoming messages (like config from server) gw.process(); distance = Dist.getDistanceCentimeter(); if (distance != lastDistance) { lastDistance = distance; gw.send(msgdist.set(distance)); } if (loopCounter == 0) { // Fetch temperatures from Dallas sensors sensors.requestTemperatures(); // Read temperatures and send them to controller for (int i=0; i<numSensors && i<MAX_ATTACHED_DS18B20; i++) { // Fetch and round temperature to one decimal float temperature = static_cast<float>(static_cast<int>((gw.getConfig().isMetric?sensors.getTempCByIndex(i):sensors.getTempFByIndex(i)) * 10.)) / 10.; // Only send data if temperature has changed and no error if (lastTemperature[i] != temperature && temperature != -127.00) { // Send in the new temperature gw.send(msg.setSensor(i).set(temperature,1)); lastTemperature[i]=temperature; } } } if (++loopCounter >= loopsBetweenTemp) loopCounter = 0; gw.sleep(SLEEP_TIME); }

@lunarok about power emission .. I test it in my house .. WiFi is different .. but in 2.4Ghz is problem with signal mirroring .. receiver detect more signal , all are same but little delayed .. then receiver not receive signal correct .. in free area there are not mirroring signal then with low output power can get long distance .. and low power consumption.. but in Built up area is better to use 868Mhz or 433Mhz .. there is also mirroring but less then 2.4Ghz . I can test only nRF24L01+ with nRF905 or CC1101 .. but in fact .. in CC1101 or nRF905 is possible to set lower transmission speed then get longer distance .. best regards.. or not ???

Please share the solution, I'm using OrangePi (quite 'better' clone of BananaPi from China), it's superb fast but would like to have nRF-serial gateway straight from board.

@hek One thing is, that salaries is much lower in China, than Europe/USA. Another thing could be that the government is funding the postal service, in order to get as cheap shipping FROM china, as possible. Doesn't explain things with itead though, but in general I would expect that it's like that.

Check the shop part of the mysensors.org website you will be amazed :) Just be sure that you buy any Arduino with at least the ATmega328. I made a mistake buying the Arduino Mini with an ATmega168 micro controller (which is also available) but this has only half the amount of Flash Memory and EEPROM. This makes it unusable for the sketches you will find on MySensors.org, and the price difference between the 2 types of Arduinos is a matter of cents.

@Terence-Faul : did you still get this issue ? around that time (1 month ago) there was a beta release of the plugin creating such error of loops, nothing about IR (my fault) @hek : IRLib decode the message, so it's not so long, around 12 characters. I use it myself, the node send to the controler any code received and you can store them. I have a scenario in Jeedom that is storing all codes receive until I erase it, like this pressing multiples button, I get all of them. After that, you can create a V_IR_SEND and as the input use any of the codes you have received. But must be working only for a protocole decoded by IRLib (at that time, I have try only my Sony remote) If not decoded, yes RAW message is too long to be used. And of course better to know what type of protocol it is so (but it's possible to send this value in another sensor for exemple) My bigger problem with this library, it's the hardcoded Sender in PIN 3 (I don't understand why, and make me impossible to use a motion sensor at same time)
