Hello,
maybe you should figure out that this new feature is only available since version 2.4…
But it works fine for switches and dimmers.
e.g.
Switch KuecheD1_Switch "Küche Decke" (Kueche) {channel="tradfri:0100:gwb8d7af2b578d:65545:brightness", channel="tradfri:0100:gwb8d7af2b578d:65546:brightness", channel="tradfri:0100:gwb8d7af2b578d:65548:brightness", channel="tradfri:0100:gwb8d7af2b578d:65547:brightness" [profile="follow"]}
Don’t forget to define a profile (in my case"follow"
For a dimmer:
Dimmer Lampe_Tisch_Brightness "Tisch Helligkeit" (Tisch) {channel="tradfri:0220:gwb8d7af2b578d:65542:brightness", channel="tradfri:0220:gwb8d7af2b578d:65543:brightness" [profile="follow"]}
or even for color temperature:
Dimmer Lampe_Tisch_ColorTemperature "Tisch Farbtemperatur" (Tisch) {channel="tradfri:0220:gwb8d7af2b578d:65542:color_temperature", channel="tradfri:0220:gwb8d7af2b578d:65543:color_temperature" [profile="follow"]}
