SONOFF S31 WiFi Smart Plug with Energy Monitoring, 15A Smart Outlet Socket ETL Certified, Work with Alexa & Google Home Assistant, IFTTT Supporting, 2.4 Ghz WiFi Only (2-Pack)

Wouldn’t connect in normal mode. Only compatible mode. Worked but kinda screwy on updating. Other ones I’ve seen update quick every couple seconds. Now it’s stuck showing the same wattage all day even with no devices plugged in. Guess I’ll update on the replacement if it works or not.

If you care about power monitoring function and/or potential to convert to Tasmota firmware, this is a serious candidate. Other than that, there may be better option around, e.g., TPLink HS103 (15A, no power monitoring) which is cheaper, has better software support and from a reputable manufacture (and UL listed). Now to get Tasmato firmware you need to have a USB-serial converter with 3.3v supply. You need to disassemble (and void warranty) the plug and solder 4 wire to connect to the serial, with the risk of destroying the soldering pad (I did on one of the VCC pad). All these are not really for average users. But if you went all the way through you got something really cool to play with.

I bought this so as display real-time power consumption. I recently purchased an electric portable heater and wanted to see real-time power consumption. Didnt happen. The picture Ive uploaded, shows the display with a 1000 watt (advertised power consumption) heater plugged in and running for 5-10 minutes. I purchased 4 of these. Tried another unit, same story. )-;

Perfecto

I love everything about this outlet, except for the power monitoring function, I wish that you could download more than just the past 3 months of monitoring data, I also dont like that the data is cloud based. A great future addition would be to have an option to view when the appliance starts up & shuts off if possible? That way you could know the total running time.

Disappointed. It wouldnt connect to phone. Based on what I read in email, it will only work if you use alexa or google or other platforms. I didnt want any platform. I just wanted it connected to my phone and it wouldnt do it. I spent 3 hrs working on it. Not worth my time. Their are other brands that are more friendly then this crap.

Works great right out of the box. Using the Ewelink software, you are presented with all the parameters and easily connects to Alexa. Just change the name during the configuration to prevent Alexa from getting her tung tied up in a knot. The only downside is that unlike other Sonoff boards, the serial connection points on the board does not have through hole pads. Several flashers have damaged the pads trying to hook up the connections for flashing alternative software. Very good value for money
