Sonoff SNZB-03 - stopped working

surge919 · November 3, 2025, 10:10pm

my SNZB-03 has been working fine for several months and today it stopped reporting.

in Zigbee2MQTT, if I ‘Permit Join’ and press the pinhole button, it shows up in the logs but doesn’t report any activity after that.

I also force removed it and re-joined it.

It shows up fine but no longer reports.

I’ve restarted the docker container as well as unplugged and plugged my sonoff stick back in

any ideas?

Stupid question:
Did you swap out the battery yet?

I’ve had some experiences with Zigbee devices, SNZB-03s included, where the battery percentage never decreased from 100% except just after replacing it:

And again, it’s been 100% ever since
