Hello @dbemowsk ,

But it worked in Pimatic,
Seems to me that then the serialgateway was working?

Strange behavior of serial gateway.

I already build it and used it with Pimatic and it works.
Now i want to use it with Domotics but it did not work.
Whem i look in the serial monitoring I see this error?
