I had the same problem. I resolved it by taking out the battery from the device, waiting a few seconds before inserting the again. After doing this the pairing worked as expected.
Already tried that (for days even) but did it again just now right after the 2.3.0 update… Still a no go. Only thing I can think of now is a complete reset of the ZigBee network. But this will be quite a lot of work and there’s still nog guarantee it will work… So I’m not sure what I should do next.
Okay I’m about to give the Zigbee network a total reset but cause I’m running out things to try. As a last test I tried to add my partially-eaten-by-dog-human body sensor and it added perfectly…
Magnet sensor… no
Vibration senso… also no
What the? I really don’t understand the logic of this behaviour…
Just reset the whole Zigbee network.
Added the vibration sensor with NO problems! Guess I’ve got some flow repairing to do tonight
Go with the flow. May the force be with you.
…I’d say: let the dog nibble on the rest of your sensors too!
Yeah beginning to consider that… I rebuilded all my flows and added 27 devices without problems, including vibration sensors and almost all of my previous other sensors. But just as before I am at a point where I can’t add additional sensors If I’m not mistaken it’s the same amount devices as a couple of days ago (27 including Homey). Really frustrating… But this time because of a different order in adding the devices I also can’t add one of my Innr120 plugs which makes me wonder if this isn’t just a general ZigBee issue. I have read somewhere there was some sort of ZigBee limit of 25 devices per router? Maybe the 3 connected innr plugs are not functioning correctly as a router? I’m getting lost again…
The Zigbee protocol itself doesn’t have such a limit, it depends on the hardware (/firmware) how many directly connected devices are supported. For Homey, I believe that the number that’s floating around is around 20, but it may not be a fixed number (just that around 20 devices, you may start to experience issues).
I think that the correct order would be to add router devices (like your INNR plugs) first, end devices (like sensors) last (so they can use the router devices). And perhaps wait a bit after adding the router devices, so the mesh can settle.
Hmm… I had the correct order in my previous Zigbee configuration, first 4 INNR plugs and then the rest. Now I’ve mixed them up a bit because I was so desperately trying to connect the vibration sensor, but it does not seem to be any different.
I’ve waited a few days and tried again, but sadly still not able to add either the Aqara or the last INNR plug.
