@andriej I have managed to get a MySensor DHT11 sensor reporting consistently in Domoticz, via the Ethernet option. My next steps are to try a couple of other sensor types (eg distance, switches) and multiple sensors on one arduino node. After a first look at how the Serial and Ethernet options have been done in Domoticz, it looks to me like MQTT might also provide a third 'transport' option for integrating MySensors, with some development. I will be building my knowledge across MySensors and Domoticz over the coming week or two, so might be able to contribute to integration development in the future.

@hek: Success! Now recieving temp and humidity readings on my Android tablet MQTT app (MyMQTT). Thank you very much for your expert advice.

Hi, I have received the following compile error for the MQTTGateway sketch:

Arduino: 1.0.6 (Windows 7), Board: "Arduino Uno"
In file included from C:\Program Files (x86)\arduino-1.0.6\libraries\MySensors/MySensor.h:28,
from MQTTGateway_v0.1.ino:60:
C:\Program Files (x86)\arduino-1.0.6\libraries\MySensors/utility/RF24.h:51: error: ISO C++ forbids declaration of 'SoftSPI' with no type
C:\Program Files (x86)\arduino-1.0.6\libraries\MySensors/utility/RF24.h:51: error: expected ';' before '<' token

MQTT Gateway is being built on an Arduino Uno (R3) with Ethernet Shield (R3), using Arduino IDE 1.0.6. I have another Arduino Uno (R2) running as a node with a DHT sensor attached.

I have successfully established a Serial Gateway to read the sensor data. I subsequently established a working Ethernet Gateway.

Now I've progressed to attempting to establish an MQTT Gateway. I am following the MQTT Gateway instructions page on the site for guidance and have downloaded the current DigitalIO and mysensor libraries.

Any assistance appreciated.
