Home Assistant MySensors plugin bug?

[NeoX]

Hi All!

I have a problem with MySensors integration in HA.
I've written a sketch with Serial transport with Arduino Mega board, connected to Home Assistant Raspberry Pi.
Now i've got following errors in log

Actually 0;31;1;0;2 is real answer from my atMega board, so what is going on here?
Tried several version of library (development, 2.4, also downgraded to 2.0), but nothing helps

Home assistant version is current - freshly installed.

Please help

Can you post your sketch, and the debug log from your node?
