Nice, looks neat, are you using the ws5100 or the enc28xx?
Are you willing to share the pcb (eagle / fritzing / etc. ) files?

ws5100.
share... a bit of later.
I had to fix some little bugs.

Very cool! Any more detail you can give on this setup?

Hey there @Chaotic ! This is Fay from codebender.cc Thank you for using codebender! I just wanted to let you know that one of the sketches you are using in this comment has been deleted and so it is not available for users to view it. Let me know if you have any question.

I have been away for a while but it seams quite some of you are experiencing problems, I'll try to take a look at it. If you find any more details, please let me know!

@TommySharp Hmm dont really remember, but I think this was the solution https://github.com/knolleary/pubsubclient/issues/46

Sorry. Hek, I using this code. Vera3 find relay and it works, but also appears 3 door sensors instead of 3 temp sensors. I try to use the my arduino board only with sd18b20 sketch and it work's and show temperature. Is it sketch suitale for vera? @Gambituk said: and here is the modified relay/temp sketch // Running DS temperature sensor(s) and relay(s) on one mysensor arduino node // Combines Onewire and Relay code // 2014-10-14 Pego: Tested and Running on Uno/Clone and MQTT gateway // Example sketch showing how to send in OneWire temperature readings // Example sketch showing how to control physical relays. // This example will remember relay state even after power failure. #include <MySensor.h> #include <SPI.h> #include <DallasTemperature.h> #include <OneWire.h>presen #define ONE_WIRE_BUS 3 // Pin where dallase sensor is connected #define MAX_ATTACHED_DS18B20 16 #define RELAY_1 4 // Arduino Digital I/O pin number for first relay (second on pin+1 etc) #define NUMBER_OF_RELAYS 2 // Total number of attached relays #define RELAY_ON 1 // GPIO value to write to turn on attached relay #define RELAY_OFF 0 // GPIO value to write to turn off attached relay unsigned long SLEEP_TIME = 30000; // Sleep time between reads (in milliseconds) 30000 orig OneWire oneWire(ONE_WIRE_BUS); DallasTemperature sensors(&oneWire); MySensor gw; float lastTemperature[MAX_ATTACHED_DS18B20]; int numSensors=0; boolean receivedConfig = false; boolean metric = true; // Initialize temperature message MyMessage msg(0,V_TEMP); void setup() { // Startup OneWire sensors.begin(); // Startup and initialize MySensors library. Set callback for incoming messages. //gw.begin(); gw.begin(incomingMessage, AUTO, true); // Send the sketch version information to the gateway and Controller gw.sendSketchInfo("Temp and Relays", "1.0"); // 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, V_TEMP); } // Fetch relay status for (int sensor=1, pin=RELAY_1; sensor<=NUMBER_OF_RELAYS;sensor++, pin++) { // Register all sensors to gw (they will be created as child devices) gw.present(sensor, S_LIGHT); // Then set relay pins in output mode pinMode(pin, OUTPUT); // Set relay to last known state (using eeprom storage) digitalWrite(pin, gw.loadState(sensor)?RELAY_ON:RELAY_OFF); } } void loop() { // Process incoming messages (like config from server) gw.process(); // 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 more then 1 degC and no error if (int(lastTemperature[i]) != int(temperature) && temperature != -127.00) { //added integer // Send in the new temperature gw.send(msg.setSensor(i).set(temperature,1)); lastTemperature[i]=temperature; } } //gw.sleep(SLEEP_TIME); //no sleep for relays!!!! } void incomingMessage(const MyMessage &message) { // We only expect one type of message from controller.

By creating the file org.eclipse.smarthome.mqttbroker.cfg in the service folder (/usr/local/etc/openhab2/services in my case, chown to openhab), with the contents name=mosquitto host=192.168.1.69 secure=false port=1883 username= password= retain=true I was able to just create the MySensors MQTT gateway (using paperui) and it stayed online (no mqtt broker defined, but its addon is installed). I had the impressions that with the latest versions it should be possible to do everything in the PaperUI, and that the broker would use the mqtt2 addon (but in paper ui, service, config, mqtt tab, mqtt system broker connection, manage->plus button -> expert mode, I get to see the contents of the cfg file above) But unfortunately, it seems that the discovery services enters a endless loop (maybe I need to update my arduinos sketch to the latest mysensors code?) and I don't get any auto discovered things. If I trigger a new discovery it will stop the previous one and start again. Finally, I was able to manually create a thing, and link items on it. Eventually my battery level and humidity were displayed in the paper ui control page (after some weird delay, not updating once it shows in the log. the temperature didn't show up though). Not sure if my understanding is off (or paperui is limited in this sense) but in the "thing" creation page I only get to specify one child id. Then my multi sensors/value nodes would need to be define in multiple things? As I can't properly define channels for each child id, and I'm not sure what var1-5 are all about. I'll try defining things/channels/items directly in files in the following days, because so far I couldn't enjoy most of the benefits of this new version (auto discovery, logical grouping of physical device in "things", questionable "do-it-all in paper ui"), and I'm almost considering using mqtt1 binding in the new install

Now the RPi based on a new install of Raspbian Jessie, OpenHab 1.8.0 and Mosquitto is up and running and the ESP8266 MQTT client does connect without any problems. I have not changed anything in the code but Mosquitto is now based on the RPi repository for Jessie and not the mosquito_wheezy one. That seems to have fixed it so those versions are likely different but I have not put any time into checking this.

Hi John, appLog.txt I also tried using datatype string but it doesen't work. Meanwhile I have studies the log files more detailed and found the following behavior: when defining the device skeletal and when updating the derived device (first approx. 25 lines in the log file V_STATUS is declared as string with values 51 resp. 52 as specified in the web interface. The entity is "Modul 433 MHz". Later on, when using the toggle switch in the web interface the value has changed in the decription in the log file (see line 164 or 185) value has been changed to on/off. With this definition it seem that the mysensors-Plugin is feeded has been changed from the specified values. My conclusion is that the change is taking place somewhere outside the mysensors-plugin. By the way, if I change the type to string do I have to use quotation marks in the web interface? Thanks a lot for your support. Martin

wdt.h is included on Arduino IDE. This example show how it's work: #include <avr/wdt.h> int counter=0; void setup(){ wdt_disable(); Serial.begin(9600); Serial.println("Starting..."); delay(1000); wdt_enable(WDTO_8S); } void loop(){ wdt_reset(); Serial.println(counter); counter++; if(counter==5){ while(true){} } delay(500); }```
