1.0.4

Beta

January 2026

Removed EP1 Level Control Cluster attribute OnOffTransitionTime.

Set the following EP6 attributes to persistent storage:

  • On/Off Cluster: On/Off, StartUpOnOff

  • Level Control Cluster: CurrentLevel, OnLevel, StartUpCurrentLevel

  • Color Control Cluster: CurrentHue, CurrentSaturation, CurrentX, CurrentY, ColorTemperatureMireds, ColorMode, StartUpColorTemperatureMireds

Removed the Mode Select Cluster from EP1–EP6.

Fixed an issue where binding could cause the device to freeze (note: when using binding, do not allow the switch to join more than three hubs).

Note: The mode select clusters were moved to their own endpoints (20-27) to better conform to the standards. This (temporarily) creates duplicate select devices. Restart Home Assistant and the “old” copies will show up as Not Provided devices (greyed out, dead) entities. Go to entity tabs and filer on Domain = Select, Integration = Matter, Status = Not Provided and you should be able to bulk-select and delete those.
