The Tapo ones are the only ones I’ve tested with their own app. In the past I’ve used Polycab and Goldmedal ones, but after flashing Tasmota not with their own firmware/app.
I remember reading somewhere in this forum that you can hook into Tapo and get readings for home assistant, it was a github project.
These smart plugs/sockets are best suited for low power or intermittent loads.
If you have a continuous power draw, these build up an uncomfortable amount of heat. I saw this even with loads of just 250W continuous, it would warm up in a day or two. There’s just no heat dissipation in those sealed plastic enclosures, so they heatsink into the pins/socket.
Intermittent loads are fine like coffee makers and geysers, or low power continuous loads like floor lamps and stand fans.
None of these are particularly robustly engineered as something dependable for critical applications, they’re meant for low priority consumer loads — a fact I learned the hard way, after purchasing about 20 of these.
They’ll work fine for simple stuff like power cycling your router and other things like that.
I do have one of the Tapo ones connected to a 2kW AC but I’m a little suspicious about the numbers. Peak usage seems fine but recorded usage over time appears to be skewed slightly, possibly due to heat build up. It’s lower than I expect or maybe I just don’t know how ACs work.
