Fehler beim Peering Wandthermostat HM-TC-IT-WM-W-EU mit HM-CC-RT-DN

manyhb · 28 Oktober 2025, 14:58:59

Beim Peeren der Kanäle Weather und Climate zwischen dem HomeMatic-Wandthermostaten HM-TC-IT-WM-W-EU und dem HM-Heizkörperthermostaten HM-CC-RT-DN mit den Commands:

Code Auswählen

set  HM_7B746E_Weather peerChan  0  HM_77BC01_Weather  single  set
set  HM_7B746E_Climate  peerChan  0  HM_77BC01_Climate  single  set

erhalte ich jeweils die Fehlermeldung 'peerChan requires parameter: -btnNumber- -actChn- [({single})] [({set}|unset)] [(actor|remote|{both})]'. Ich kann keinen Syntaxfehler erkennen.

Bei der Einrichtung habe ich mich orientiert an dem Wiki https://wiki.fhem.de/wiki/HM-TC-IT-WM-W-EU_Funk-Wandthermostat_AP,
und ja, das Tutorial habe ich gelesen, auch den HomeMatic-Anhang.

Das Pairing hat offensichtlich für beide Geräte funktioniert:

'update check' und 'update' sagen mir: 'Downloading https://fhem.de/fhemupdate/controls_fhem.txt
nothing to do...'.
Auch 'update all' und 'update force' bringen da keine Änderung.
