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 buy hundreds of stuff on AE, but I’ll never buy something that plugs on AC, it’s all weak and not tested. You play with fire.
I’m with this. There’s a huge variety in the quality of electronics components that change with cost. And relays are one of those things that can get really shitty with cost and the good ones aren’t cheap. Running wall power through shit relays can start fires. So if it plugs in the wall, it’s gotta have a western brand and UL/ETL/MET logo on it.
