I have no idea, sorry... Personally I use node red for automations, from there you can just address the node and child directly even when it isn't presented or not supported by home assistant.

@rvendrame This issue does not seem to be related to MYSBootloader since the log does not show bootloader messages. However, your node seems re-initializing (but not rebooting) over and over. Try changing the hardware (MCU & nRF) and update to the latest (non-dev branch) framework for further testing.

Using watchdog as Mysensors is good idea, but is there any other better way to archive same?

Ive designed a NRF based mysensor remote with 14 keys, I want to use pin 2 for one of the key. Currently all pin work properly for key but pin 2 does not recognise instead it creates some disturbance in transmission. what i receive on destination node is unexpected. Is it possible to disable use of pin 2 . it looks like mysenso uses pin 2 for some internal use.

@rvendrame I have this issue with my Arduino Pro 5v's, (which I bought from the link in the MySensors store page). The only fix I have found is to manually define to node for those sensors. Annoying, but it works.
