Weird disconnect always at the same time

1

I have what I feel is a fairly big setup, 200 odd Zigbee devices, a few dozen Z-Wave and 70 odd Wi-Fi, The system has always been very stable, it’s all tied in with Google and I am in the process of adding some local voice control, got 2 speakers and they also seem to be working well.

This has al been stable for months, a couple of nights ago, I woke up for a rest room break and noticed a light on, turned it off and went back to bed, this has happened 3 nights running, On checking the history of that device I noticed this…

On checking back a bit further this has happened on every device at exactly the same time every morning, there is no fluctuation the the power to the house or any fluctuation in the internet.

Any ideas?

Thanks.

UPDATE - This seems to be only ZigBee devices.

You, or someone near you, have a device that interfere with the ZigBee channel.
It can be anything that cause the interference.
