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?
