Just a great thing I experienced. One of my rollerblinds from Ikea (Fyrtur) lost its connection to the Zigbee network. I saw the pain of needing to remove it, add it again and fix all flows. But the solution was simple.
- Don’t remove the device
- Press the two buttons on the rollerblind (5s) wait for it to start blinking
- Add the device in homey as normal
- It will say it already added and you need to un-pair it to add it
- Cancel the device add
- Now it works again
Hope it helped someone!
