I've been able to get MySensors working with HomeGenie using the MQTT gateway. It doesn't have two-way communication or software-based pairing yet, but I'll work on those in the future.
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);
}```
@alexeinz figured it out, apparently had to add experimental and get latest mosquitto for the conf file to work correctly , now the bridge is working perfectly
--- broker.conf file in /etc/mosquitto/conf.d
the topics coming from gw will appear under sensor/# on mosquitto
connection MMQTTtoSensor
address 192.168.1.234 <-gw ip
clientid MyMQTT
cleansession true
notifications true
topic # in 2 sensor/ MyMQTT/
Might be helpful for somebody... Things configuration for OpenHab2:
Bridge mysensors:bridge-eth:gateway_2 [ ipAddress="192.168.178.50", tcpPort=5003, sendDelay=200, enableNetworkSanCheck=true ] {
/** define things connected to that bridge here */
light sonoff01 [ nodeId="0", childId="0", requestAck=true ]
}
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.
Just one final question... is the approach to MQTT correct or should I stick with simple Ethernet? I was planning on using OpenHab or Home Assistant.
Thank You all

Hmm dont really remember, but I think this was the solution

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?
