Hallo zusammen,

obige Fehlermeldung erhalte ich jedes Mal beim Start von OH.
Es betrifft genau die beiden Heizungsregler, die mit einem Wandthermostaten verbunden sind. Die, die einzeln arbeiten funktionieren.
Hat jemand (Ollie) eine Idee dazu?
Ich habe das heutige und vorherige Binding getestet.

Gruss
Stefan
