Hello!
I am new to this discord and HA in general 👋

I've set up 6 IKEA Timmerflotte using ZBT-2 with Matter over Thread. After the inital challenges of setting up my network and pairing all 6 devices everything started to look smooth and stable.
However, a couple of days later one of the sensors became unavailable to HA and I was not able to ping it or get it back to available. I resorted to waiting it out for a bit and it seems to have resolved itself within 12 hours and it was back online again. Now a second sensor has become unavailable and it is not resolving itself really this time (This sensor is located close to the ZBT-2 and it is not obstructed in any way). I guess I could factory reset the device and set it up again but I dont feel like this solves the problem long term so I'm wondering if anyone else have similar problems and have you resolved it somehow?

Firmware is updated to 1.0.21.

I am also having this issue with the TimmerFlotte becoming magically unavailable, though I have zero issues with my other end-devices

Nothing to add otherwise as to how it can be resolved. I’m clueless

Update: today it finally reconnected to my system after being unavailable for about 48h.

Interesting, I have the same problem

I’ve had this discussion with people on other forums as well which seem to have the same issue too. It disconnects seemingly randomly and reconnects after 12-72hrs.

#

Since I don’t own any other device from IKEAs new Matter-series I don’t know if this is an overall issue or if its limited to the Timmerflotte.
