MySensors and Home Assistant - using MQTT

[Mihai]

I have successfully built and tested MySensors 1.5 and 2.0.0 beta with Home Assistant using MQTT with slightly modified sketches , few more words here: http://forum.mysensors.org/topic/2747/home-automation-multi-sensor-nodes.
The node ID was declared manually for each node.
The topics description was not very clear from the beginning, but finally I got them and now several examples of many sensors types are included in the configuration.yaml file.
I did not succeed to make them to work together using the Serial Gateway, but MQTT is just fine (may be better from some points of view).
