- Maybe this is of any help
Fixing disconnected Zigbee devices (without having to modify all flows) - What is the distance between Homey / zigbee router device and the roller blinds? Can you add a zigbee smart plug (Tradfri) between Homey and the blinds?
- Did you check the Wifi & zigbee frequencies, don’t they interfere?
- Did you update Homey to v5.0.2 or up? And did you (optionally) reset your zigbee after that?
