Hi

I have a node with DHT22 and a DS18B20, using this code.

/**
 * 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.

    #endif
 
      // Send in the new temperature
      gw.send(msg.setSensor(i).set(temperature,1));
      // Save new temperatures for next compare
      lastTemperature[i]=temperature;
    }
  }
  gw.sleep(SLEEP_TIME); //sleep a bit
}

This is what i get from the sensors.

Try if this works better? I use PiDome as the controller.

Merry Christmas all,

And thank you all that have contributed to the project.
