Tasmota compatible
I have about 15 of these now, all flashed with Tasmota and controlled with Home Assistant. These are the perfect cheap smart plug. Protip - wish I would have tried this 12 units ago, but you do not have to solder wires to the pads to flash these, you can carefully place some small alligator clips on the pads. To flash, I'd highly recommend this USB to TTL adapter: amzn.to/462UO70

These have been dependably solid devices
These have been really good for me. I’ve been using them for years now. I can turn devices on and off anywhere in the world over the Internet and I get text messages telling me when there’s been power interruptions. The power monitoring could be better, although you can’t expect much in saving a long duration of power usage for a device. The configuration can be a bit cumbersome if you’re not used to it so just pay attention to the instructions and I’m sure you’ll get it to work.

Buen producto
Es un buen producto, funciona correctamente. Lo único que no me gusta es su tamaño y que al desconectar algún cable siempre se desconecta la toma inteligente de la toma instalada en la pared.

I have these all over the house
I think I have about 18 of these. I've installed Tasmota on them, which is extremely easy to do (tip: speed it up even more and avoid soldering by getting some of those spring clips). I've gotten to the point where I have Tasmota installed on each one in about 5 minutes start to finish. I use them for several appliances solely to monitor power usage (things I'd never shut off, like the fridge), and with Tasmota you can disable the ability to shut them off.I had one that didn't work - the relay never triggers power to flow. Unfortunately I didn't open the package and discover the issue until after the return period had expired. So, that one is on me. But otherwise they work great.

Perfect for ESPHome and Home Assistant
I bought these Smart Plugs to reflash with ESPHome and integrate into Home Assistant, and they worked perfectly! The flashing process is a breeze—there are labeled pads that you can clip onto to program, so no soldering is necessary. Once set up, they function flawlessly and provide reliable energy monitoring. Highly recommended for anyone looking to customize their smart plugs for home automation!

Easy Esphome integration
Switches seem on par with other smart switches build quality wise. I did disassemble these to reflash them with Esphome in order to get then integrated with Home assistant. So far I have not had any issues with these and would buy again.
