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)

After four months two of the four units stopped working. They still function you can turn them on and off with the button however they will not connect to Alexa app, which makes them useless to me. (Edit) All 4 have stopped working now. Have replaced with Govee outlets that function just fine. This is a horrible product !! Stay away.

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.

I used with Tasmota to connect to Home Assistant. It adds a lot of other capabilities. Good even for just monitoring the power.

Estos enchufes solo funcionan a máximo 2 metros del router. Más allá no tomarán señal de wifi. Tengo unos más baratos y toman señal hasta 50 metros, una decepción los eschufes sonoff, literalmente solo funcionan al lado del router.

I bought a few Sonoff switches years back and needed more smart plugs. So as to limit my app-footprint, I ordered more Sonoff. Price is higher than other smart plugs but to keep my system with as few Chi-com manufacturers as reasonable i had to go this route. If you dont know there are 2 types. One offers live electrical useage stats and the other is basically a switch only, no data. They setup easy and work well. I never have them go off-line or die. I wish their price was about half what they are. Shipped fast.

I bought this device pack to monitor my servers power consumption. I got the package today. The setup was a bit confusing between Quick Pairing Mode and the Compatibility Mode. Lesson learned: Make sure your smart phone is pre-connected to 2.4 GHZ WiFi network. Otherwise quick pairing will not work. Once configured there is not much you need to do, other than naming the device and your room(s.) Right off the bat I have two complaints: 1. The big off switch on the App turns off the device with no prompt. A prompt, are you sure, would be very nice. 2. WiFi network requirement is for 2.4 GHZ. Granted, I do not need the speed but modern 5 GHz routers provide a better range as well. Other than that, for now, I like the device. I can monitor the power consumption in real time, which is what I was looking to do.

I love these smart plugs, it’s very affordable and it really works. You can monitor all your appliances for power consumption and integrate in home automation with any kind of platform - alexa or google to name a few.

I do like this device especially since its so much cheaper than other devices similar to it. But you do pay for that in some ways because it doesnt have a fast rate of updating. So it seems to freeze occasionally for 10 to 15 seconds and then other times it will report every 5 or so seconds. For my purposes it does just what I needed to.

I chose these specifically for the history and current-usage software. And also because they allow up to 1800w of power - so I can use them to track space-heater usage! App works great and was super easy to set up. Plugs have an on/off button right on them, giving you manual control when you don’t have the app. Basically same price as comparable models, so worth it for the extra electricity capacity and the app’s UI!

I cracked this baby open as soon as I received it and flashed Tasmota onto it without any issues. Works great!
