I’ve got a couple of Zigbee plugs, all work well, except one I use for the washing machine. It randomly turns off. When I check the history in HA, it just says that it turns off, no source. My guess is that it trips, ie temporarily exceeds 10A. The plugs are rated 10A from Aliexpress.
I have not encountered this with my Sonoff Zigbee plugs, for whatever that is worth (US split phase). I also haven’t put large appliance loads on them.
