Hello !
Je viens vous partager ma solution finale :
-
Dans HA, j’ai seulement créer un input_select pouvant prendre différentes valeurs sous la forme d’une chaine de caractère ( froid / chaleur / auto )
-
Dans Nodered j’ai ensuite créé un flow qui en cas de changement d’état de l’input_select, traduit la chaine de caractère sélectionné dans HA en nombre (froid => 0 / chaleur => 1 / auto => 2) puis va écrire ce nombre à l’adresse Modbus qui va bien
Cela me parait la solution la plus simple, cependant il me reste à mettre un second flux qui mettra à jour l’input_select au cas où quelqu’un change localement la valeur sur la PAC.
Voici mon flow nodered complet
