What could be causing my Aqara sensors to become unavailable within minutes of each other

I’ve got 14 Aqara window/door sensors and 6 Aqara motion sensors.

every couple of months, seemingly random groups of 2, 3 or more of these sensors become inactive at the same time (within a minute or two of each other).

I go around the house and re-Add them. They will work for a few hours and become inactive again within a minute or two of each other.

After serval “re-Addings” they eventually stick for a few weeks but then it starts all over again.

My thought is to look at some logs but, I’m not sure which logs to look at and what I’m looking for.

Seems to be happening at the same time every day

Same thing is happening to me @Stavros . Were you ever able to find the root cause for this?

I was searching for possible root causes in the internet and found that migrating from ZHA to Zigbee2MQTT might fix this. Not sure if that is true.

I have not @Tinkerpop . It is so annoying and make many of my automations and alarm unstable.
I want to love these devices but it is difficult

I can totally relate to!
