I’m struggling with the right way to remove a zigbee device from my zigbee network without disturbing the integrity of the network itself.
What I experienced :
2 Weeks ago I removed an Ikea smart switch (mains powered, so with router capability) from my network and since then (couple of days later) I have problems with several Ikea door sensors (parassol). The observed behaviour is that the parassol devices send signals which are never received by my homey. Either opening, or closing is not detected, and the device remains in the previous state.
Removing and placing back the battery is enough to get the device working again.
My setup
I have a Zigbee network connected to my Homey Pro 2023, with approx. 8 smart switches, and 12 sensors. All Ikea. The problem happened soon after I removed one of the router devices. Before that the network was rock stable (2 months since I set it up)
I’ve read about Zigbee, and learned it should have an auto repair that can take a couple of hours. But my network didn’t repair itself until it was stable again.
Question
What is the right way of removing a Zigbee device with router capability from my homey?
Thanks for your help, Ruud
You would go to the Settings section of the device and tap the ‘Remove device’ button.
If that device acted as a router for other devices, then they might lose connection with Homey. You then either wait until the Zigbee network self-heals and assigs a new route to those devices, or you can repair those devices (via the maintenance option in the device tile) and force the selection of a new route.
As part of the repair procedure you’ll have to put the devices in pairing mode (follow the on-screen instructions).
This all assumes that an alternative route is actually possible, i.c. another router is in reach of those devices.
Thanks @SunBeech for confirming / clarifying.
The method you describe is what I did 2 weeks ago for the device to be removed.
Apparently self healing didn’t work, as I’m still getting new failing devices almost daily.
For all new devices failing in the coming period, I will do the repair as you describe!
Let’s see how that works out.
Thanks for your suggestions.

And mind the range factor. There should be an other zigbee router device within range.
It’s very well possible you’ll have to re-pair, or repair the related sensors several times before they “get the message”.
Do the re-pair or repair at or near the mounting points of the sensors, not near Homey.
Battery powered devices need to be kept “awake” during the re-pair or repair pocedure, by pushing the unit’s pair button around every other second.
Thanks Peter, I followed your suggestions while doing a repair action.
So far so good … (waiting for the next device fail 
)
