Sonoff Pow R2 Smart Wifi Switch Controller With Real Time Power Consumption Measurement 16A/3500w Smart Home Device Via iOS Android

Connecting the cables was easy. N = null,blue Cable, L = line/fase/phase Brown Cable, E = Earth yellow/green Cable. Make the copper part longer then you would expect. Else you can just draw it out without any force! Test your way until you have the right lenght. Bad connections may cause big problems! Talking about problems..Connecting to my wifi was problematic :) I first had to turn off the 5 GHz network by changing settings on my wireless router. I had both 2.4 and 5 GHz activated and since you are using your phone, the phone can only connect to a 2.4 GHz network else it will not talk to this device. I could not tell my Android phone to just connect to the 2.4 ghz network so I had to change it o n the router and disconnect/connect afterwards. (After everything is working you can change it back) Another problem was that it still not worked to connect to my phone. I then read on a forum that I had to disconnect my phones 3G/4G. As soon as I did that AND pressed the button on the device until it blinked faster (not just three blinks - stop - three blinks) and non stop, it connected immediately. a matter of seconds. <10 The firmware updates went fine on two out of three device. I kept hanging on 90% on the third. I was wondering what I did differently this time, but then I realised that I added the kwH price before updating. I took away the price and updated again. Worked instantly. Coincidence?? Not sure. I thought it would be nice to write here. It might help someone else. Overall I like this device and the low price for what you get for it. Enjoy!

I use several of the sonoff pow r2. In each room on extensions, on lights, tv, radiators, 3000k radiators work ok, kitchen fridges n microwaves. All fine. Controled by alexa and ewilink app. And android phone. Monitor all your electric n power in each room, program all things on n off saves electric billd. Use sonoff ht16 to read temperatures of each room turn on fans n heaters when required. All off when you want it off. Fantastic divice and sales I would recomend it.

Easy to use with the stock firmware and app, I also added it to google home etc, no problem. Later I flashed it with Tasmota firmware and am using it in Home Assistant to report energy usage as well as switching power. All in all a nice unit, although I haven't tested with anything close to it's rated 16A.
