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.

I can nothing say about OpenHAB or PiDome but: Started! 0;0;3;0;9;read: 0-0-0 s=0,c=0,t=0,pt=0,l=0: 0;0;3;0;9;version mismatch 0;0;3;0;9;read: 0-0-0 s=0,c=0,t=0,pt=0,l=0: 0;0;3;0;9;version mismatch Does not look good, it seems an error from the gateway.

@sentur since it was launched 6 days ago, I seriously doubt anyone has had the ability to try it. Anyway, please don't post the same question in multiple places. It wastes people's time. Most users don't have as much time as they would like to spend on projects, and wasting their time by splitting the discussion to multiple threads isn't very nice. In case anyone wants to follow the existing discussion, head over to https://forum.mysensors.org/post/84076

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.

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.

@catcher Thanks, I tried this Perl script and it is working out of the box with OpenHAB2! And I'm sending with MySensors 2.

Ive started out with openHAB2. I was using a Ethernet gateway and tested the mysensors binding but found the combo was too limited. I much prefer having the MQTT gateway and the data be accessible to anything that subscribes, although I also now use openHAB to republish its item changes to MQTT as well which is probably a better approach. I don't think the main new features in version 2 are very mature at the moment as well, discovered things for example get put in to a non human readable database and the web ui's are not fully functional. With that being said I'm using node red to provide node ID's and configuring items manually and since beta3 it's been solid as a rock.
