SONOFFPOWR320D Elite 20A WiFi Smart WiFi Wireless Light Switch with Energy Monitoring, Universal DIY Module for Smart Home, Works with Amazon Alexa & Google Home, No Hub Required

The device was easy to install and I can now monitor my consumption and turn on and off devices and understand their electric usage.You’ll need a paid subscription to be able to extract that data and plot it in your own DB.

These units work exceptionally well and are a bargain for what they cost. The setup is simple and the eWelink app works with them very well. The WiFi connectivity was straight-forward and the stats are helpful in monitoring usage. I have not made use of the timer or power limit features, but they look to be very flexible. It was possible to configure the units to default to either "on" or "off" and in my case, "off" was essential, so that is an important feature. Highly recommended product.

I have it working with Tasmota 12.2 only problem is the LCD versions will have a flakey LCD after you disassemble to program it. if you open it from the back left to right is 3.3V T,R, Ground. These are labelled on the other side, but if you remove the board you will get a flakey LCD as they use the rubber zebra strip for the data display.I wish they would just solder on the $0.10 header pins at the factory and charge an extra $1.00 for it so the tinkering crowd doesnt have to fight trying to ge tthe display working again.

I purchased this for my rental property. Rather than purchasing another meter from my utility company for my downstairs apartment which is rented out I installed this. With the app I'm able to connect and view tenants energy usage, remotely shut of power is necessary.

Funciona perfecto para mi calentador eléctrico 110v

No enciende, en la app dice que necesita cambio, llego con problemas y no se puede usar.Es un buen dispositivo compre otro y me funciona de maravilla pero este llego dañado por eso una estrella.

Este item me ha funcionado bastante bien, al principio tenia problemas porque no mostraba rl consumo pero era error mio, otra cosa es que si se cortaba la electricidad este medido se quedaba apagado cuando la electricidad regresaba y tenia que encenderlo manualmente.Hable con el soporte y me recomendaton activar algo en la app lo cual corrigio el problema.Definitivamente lo recomiendo, estoy pensando en comprar el que mide la temperatura y la humedad.
