And again, 2 devices went offline at the same time.
| No. | Name | Room | Type |
|---|---|---|---|
| 1 | Wasserlecksensor | Küche | M/T |
| 2 | Wasserlecksensor | Badezimmer | M/T |
All of them are battery-powered, different rooms and two very different connection paths.
Time: 15:14 UTC ± 10 minutes
Same email address, logs dumped.
Wait a minute!!! This happened at almost exactly the same time before!!! The last time they went offline, it was at 15:13 UTC:
Today it happened between 15:12 and 15:14 UTC.
Hi, @Andreas_Roedl
Just to confirm:
Always these two IKEA KLIPPBOK M/T water leak sensors - at the same time. Sometimes with other battery powered devices like IKEA BILRESA or Aqara FP300. These IKEA KLIPPBOK are the most notorious. It’s interesting that they go offline at the same time, but have different connection paths.
Do they go offline every day around the time mentioned or only some days?
Sadly not every day - that would make the debugging much easier. Can’t figure out a pattern here. Maybe every other week.
I see they are both Matter sensors of the same model. Do you have any other device that is from the same model that doesn’t go offline?
Only these two devices of the same model.
Weird how they go offline at the same time. When they go offline the next time, I will bring one of them back online and wait an hour before I bring the other one online (by pulling the batteries for a few seconds). That way we could find out if there’s some timer or buffer overflow happening.
Edit: currently the same connection path for both devices, after I brought them back online, but they had different paths when they were offline. Plenty of Thread routers to choose from.
Thank you for the information.
I created a report to see if the engineering team can find something and I’ll keep you posted.
I have several KLIPPBOK (on software 1.11) and my V4 hub is also running Beta firmware. Mine are fairly stable, the only battery powered device that goes offline on a daily basis is that CO sensor we’ve discussed in a separate thread.
Did your KLIPPBOKs update their firmware? Mine pulled an update straight out of the box.
I would like to add that I have been experiencing the same issues with the KLIPPBOK water leak sensors. These sensors have the latest firmware update. I would also see the drop-offs on my Primary Thread Border Router. But I should also point out, I had been experiencing this issue with 59.x so it is not limited to 60.x Beta.
Jump to last night… I removed ST’s Thread network from the Primary Thread Border Router (Apple Home) and I have not experienced any drop-offs of the KLIPPBOK water leak sensors since.
LOL - of course right after posting - one went off-line. 
but 60.9 was just pushed out.
In the first minutes after installing them.
So did mine. My V4 hub is on Beta 60.x firmware, and the KLIPPBOKs have been absolutely stable. One connects directly to the hub, three others found a connection path through a KAJPLATS lamp.
