@mihai
Thanks Mihai, I have been struggling with getting my first basic Home Assistant + MySensors via MQTT working. Your examples got it all going for me. Thanks again for taking the effort to post.

Hi,
I have been running OpenHab, Mosquitto (MQTT broker) and some home brew gateways and RF nodes. I have seen the light and clearly the MySensors platform and Home Assistant as my controller are the way to go. I've had a good go at getting it to work and I feel I'm close, but now I need some help.

I have a Moteino with RFM69W configured based on the sample code here https://home-assistant.io/components/mysensors/ and have put a switch (fixed not momentary type) on pin 8.

I bought a SenseBender GW board and soldered on an RFM69 and plugged in a W5100 Eth module. I used a combination of running the Examples > MySensors > SensebenderGatewaySerial example and the Examples > MySensors > GatewayW5100 example to creat my MQTT GW code.

I used the sample Home Assistant configuration.yaml code from here https://home-assistant.io/components/mysensors/ but customised to just use the "- device: mqtt" section.
I also added an mqtt broker section to my configuration.yaml
My Home Assistant is running on an RPi3.

So whats the problem?
Well, when I press the button on the end node, it successfully transmits what looks like the right info to the gateway and the gateway in turn shoots the right MQTT packet over to the MQTT Broker (mosquitto) and then Home Assistant seems to receive it.
BUT unfortunately Home Assistant then instantly generates an error

2017-06-29 18:06:56 DEBUG (MainThread) [homeassistant.components.mqtt] Received message on GWPUB/55/11/1/0/2: 0

homeassistant.exceptions.NoEntitySpecifiedError: No entity id specified for entity Switch Sensor 55 11

I will raise this in the Home Assistant forums as well, but I would like to know if anyone can assist here with checking the my MySensors stuff. Or provide some examples of known working configs?
Thanks,
Paul

Here is my SenseBender MQTT Eth w5100 Gateway 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.

*******************************
*
* DESCRIPTION
* The ArduinoGateway prints data received from sensors on the serial link.
* The gateway accepts input on seral which will be sent out on radio network.
*
* This GW code is designed for Sensebender GateWay / (Arduino Zero variant)
*
* Wire connections (OPTIONAL):
* - Inclusion button should be connected to SW2
*
* LEDs on board (default assignments):
* - Orange: USB RX/TX - Blink when receiving / transmitting on USB CDC device
* - Yellow: RX  - Blink fast on radio message recieved. In inclusion mode will blink fast only on presentation recieved
* - Green : TX  - Blink fast on radio message transmitted. In inclusion mode will blink slowly
* - Red   : ERR - Fast blink on error during transmission error or recieve crc error
* - Blue  : free - (use with LED_BLUE macro)
