SONOFF POWR320D Elite Smart Power Meter Switch with Wi-Fi, 20A Max Load, LCD Screen, 6-Month Historical Data, Overload Protection, Push Notification Support Voice/LAN Control

Using this to schedule power on/off my EV car charger as I plug in the charger in evening with a auto cut off early night and then switching back on in morning. Does perfect job and power consumption reading is very accurate and precise. Definitely a recommended product for home use. Planning to buy another one for my AC as well. Price could have been slightly cheaper, but surely no complaints on the useability.

Don't buy this product because your daily power consumption data was lost in app if your sonoff power metre in not connected to the internet.... Product was not save daily data in device. Accept device display show total data only.....

This product does not work when it comes to App. See the difference between App and device in photo. If app is you priority then this is not the product. till today there is not a single product which works accurately in app. I even tried different company device that is also not working. I even complained by email to sonoff company. They reply to our email after 2 days. "No" customer care number available. Worstest service and worst product. Absolutely 100% waste of money.

Parfait pour suivre la conso de mon VE. Rapide d'installation et superbe qualité

I purchased this Sonoff Power Monitor on a hunch as i couldn't find any information on it to see if it would work in a bidirectional way - ie to monitor wattage going in rather than out. I have a few sonoff products around my home and always find them to be great pieces of technology that work just how they are suppose too. You need to have the eWelink app installed to get the most out of these device, the app is free and easy to download. Connecting up this device was a breeze there are very decent quality connectors for you Live and Load inputs, and installation only took around 5 mins. Unfortunately as with all sonoff products i own there is no earth connector so i had to make my own. Once powered up i was extremely pleased to see that it was indeed bidirectional and measured the wattage and ampage coming in from my solar array. Checking the app i was able to watch the wattage from the panels increase as more sunlight hit the panels. The only thing that didn't work was the wattage as this displayed the grid wattage rather than the solar voltage, but Watts and Amps worked great. Remote control of the device was also great, i was able to switch on and off the mains portion of the device without issue from the device and the app. For standard appliance use, you can not go wrong with this energy monitor - it seems to be very accurate and will feed the data directly into the app, or you can just look at the LCD display - i do wish there was a backlight on the display as it was at times hard to read. Love this device! Recommended product! I hope that you found my review helpful.

Funktioniert top! Hab den Switch für meine Sauna zum Schalten gekauft. App und Alexa Integration war easy.

Great

Lo tengo conectado a la luz del trastero y me permite desde casa tenerlo controlado, se puede usar para controlar el consumo pero la utilidad que le doy también es muy válida
