Continuing the discussion from Möhlenhoff Alpha BUS - Solution:

Hi all togehter,
I’m preaty new to openHAB and have some problems with the same heating system from Möhlenhoff.

Firstof all I got it running but the log file give me some warnings and I have now clue why…
this ist the warning:

As far as I understand is there a problem with the XPATH expression.

Channel → State Transformation


Item → XPath Expression


I would aprichiate if somebody can help me!

Thank you.

That error message comes from a profile, a modifier you chose to apply to a channel-to-Item link.
If you’re doing your transformation in the channel then you do not usually want to do another with a profile. You certainly don’t want to apply XPATH if you’ve already done that in the channel.
