Review: Perfect for Home Assistant or ahy other Home Automation - These are the “bees knees” for anything you want to control by timer or schedule, etc. They work with the Chinese app or with other apps like Home Assistant. Wish I had a hundred of them! Definitely recommend for anyone looking to automate their home.
Review: Good energy monitoring plug - For a long time, I got these because they could be flashed to ESPhome with little effort. I wanted them for home energy monitoring in home assistant. Taking them apart and flashing them wasn't difficult but it was time consuming and you needed to have some know-how. Now, these are natively supported in home assistant, so you no longer need to flash them to get them to work, they just work, and you get all the energy monitoring and remote control you need. Overall, if you are looking for remote control of outlets and want energy monitoring, they are a decent choice for the price.

### ⭐⭐⭐⭐⭐ Tasmota-compatible Smart Plug as of December 2023. Hard to fit two side-by-side
*by C***T on December 17, 2023*

Sonoff has been a longtime reliable vendor of Tasmota-compatible devices. Unfortunately, some of their newer devices such as the S40, make it more difficult to install Tasmota firmware. This S31 though is great, with one or two minor gripes. Firstly, it's wonderful in that there's no adhesive or ultrasonic welding in sight, and it's assembled in multiple pieces held together with screws. One other major positive is that it does power monitoring with the CSE7766 which is a calibration-free electric energy measuring chip, accurate to +- 1%. It's easy to disassemble it and put it back together again without breaking any plastic. Once inside, there are easy to access pads to solder or use a BDM frame and a jig. Then it's a simple matter of connecting a serial programmer to your computer (another ESP8266 works, a Raspberry Pi works, or a dedicated FDTI USB dongle works), then going to the Tasmota Installer ESP Web Tools website, and hitting connect/upload. That flashes the Tasmota firmware onto the ESP inside the Sonoff S31 and then you're done! As for my minor gripes about this product, one is that it's slightly too large to fit two side by side in our outlets. The S31s are larger on the edge near the wall compared to the front, probably to make the molding process easier, but it's a millimeter or two too large to have two sit comfortably next to one another. My other gripe only came about after experiencing the SwitchBot Smart Plug Mini, and it's that the S31 power button is actually pretty small. All in all though, the S31s have been my go-to Tasmota smart switch for years, and while I'll probably buy SwitchBots as long as they're still flashable, this is a known good backup.
