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)

Great smart switch from an excellent company. These are rated at 15 amps and they monitor power usage also. Fully compatible with Alexa. And have an excellent control application. If youre into Home Assistant you can easily flash these with Tasmota and goto the next level. Highly rated A+

Adding new devices can be daunting at first, but once you get the hang of it, it becomes a breeze. The ability to monitor appliance energy consumption is a definite plus, and being able to schedule the ON/OFF times is only second to being able to remotely power on, or turn off anything plugged into the unit.

***Not Tasmota compatible. This was my own mistake.*** These probably work perfectly in the advertised cloud interface, and integrating with Alexa, although I wont be using them in that capacity. I mistakenly purchased these to flash with the Tasmota firmware, as Im trying to make my own, locally-controlled smarthome environment. I was unaware that this new model is not based on the ESP8266 like previous versions were, but instead they are built on the BL602 chip. I found some talk of a similar custom firmware for BL602 IoT devices and I will be attempting to use it, but if you want to flash custom firmware onto a smart-plug, just get the older model and avoid this headache. These are nearly impossible (and probably dangerous) to disassemble, and the community around this chip is not nearly as large or well-documented as the ESP community is.

The Android application itself it quite underdeveloped. It has basic features like a timer, usage graphing, and naming conventions, but lacks any sort of optimization.

This has been our favorite smart plug for quite some time. And now being UL listed just edges it up a little higher. Two of the plugs fit fine in the same socket without forcing anything. If you want to manually flash them with Tasmota or some other open source firmware, the WiFi PCB on them is the same as it was previously so all the profiles/templates will work just fine. The product is still held together with screws and no glue so it goes back together super easy.

I used tiny spring clips on a USB cable to connect to the board inside and flash Tasmota. Worked great! Unlike the KMC 30153 where they changed the underlying SOC chip (so you never know what youre getting), these have real Espressif 8266 chips in them.

Once I realized these are not a plug-n-play type of smart plug that requires third-party software I returned them immediately.

Using them with Alexa, very reliable, never had a failure/need of reset. Easy setup and Alexa integration with the ewlink app. In the ewlink app you can turn on some features that Alexa do not have but still works with Alexa, additional bonus. E.g automatically turn off the device after xxx time has lapsed since power on, power on state, timers and loop timers. Very useful for my setup, controlling a water pump for my house remotely.

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

Wifi loose connection all the time, device became useless,
