Xiaomi Aqara motion sensors randomly stops working

Third party integrations
1

Hi,
I’m running Hassio on a Raspberry, and I have two Xiaomi Aqara sensor, connected through the deCONZ Conbee 2 gateway.
I have used them for several weeks without problems, until last week; now I am experiencing a weird issue: after a random time (few minutes or few hours) both sensors stop detecting motion… then, after a random time again, they both start working again and so on, in a “continuous loop”.
When the problem shows up, it affects both sensors at the same time, even if I they seem regularly connected on the Phoscon webapp… simply, they don’t change their status!
Both battery level are at 100%.

What I tried (without luck):

  • rebooting my Raspberry
  • updating Conbee 2 gateway firmware
  • updating deCONZ add-on
  • updating Core to last version (core-2021.3.4)
  • updating OS (5.4.83-v7)
  • pairing devices again
  • changing zigbee channel

I remember that a few days ago I updated the Samba add-on to the last version, and apparently the whole thing showed up after this, but I can’t imagine any relation (by the way, I disabled the add-on and the problem persists)

I have other zigbee devices (such as Ikea and Philips motion sensor) but they aren’t affected by the issue.

So… I’m stuck on this! Do you have any suggestion?

I had an odd problem with those devices. I was running a xiaomi gateway and was switching to zigbee2mqtt. While I was transitioning I had 2 sensors next to each other(1 paired to gateway and one to z2m). The system wasn’t detecting movement and it drove me and the family crazy.

I moved the sensors further apart and it came right. So simple but so unexpected that they interfered with each other to that extent.

But I didn’t touch anything in my setup! The problem apparently started out of the blue (after updating the Samba addon)
As a last resort, I’ll try to restore an old snapshot… let’s see…
