Zigbee devices (all) disconnected

Hi everyone
Tonight all my zigbee devices went offline, all at the same time. As nothing changed (it happened while I was sleeping)… I can’t find an explanation…
I tried unsuccessfully to disconnect/reconnect one of my bulbs…
I unplugged and disconnect the batteries for 1hour, and replugged… with no luck
Thanks for your help/advice
best,
Greg

How close is your ST hub to your wireless router?

I have several routers (4) but the closest one is maybe 40 cm…

Assuming it is not related to any of the EU issues, you may want to try moving it 3m from the routers if you have a long Ethernet cable and see if that has any effect.

thanks, I’ll try this right now !

no better after moving away the hub…
