SONOFF S40 Lite 15A WiFi Smart Plug ETL Certified, Smart Socket Outlet Timer Switch, Compatible with Alexa & Google Home Assistant, IFTTT Supporting, No Hub Required -A Certified for Humans Device

I have flashed the units with ESPhome, and am very happy with them. They have a great Wifi signal range, and am nothing but happy with them. To flash them I had to open them up and solder a few wires, and I was surprised to see the build quality of the PCB. They are using their own Wifi board, not like many other commercial units out there, which are using the standard ESP modules. And judging by the Wifi signal strength they did a very good job! Highly recommended if you want to have switched plugins which you can easily flash with alternative firmwares...

The item description says S31 Lite, The Lite is only a switch than can be controlled by local switch, cell phone app, or home automation (Alexa, Google Home, etc.). The S31 that is not a Lite is a much better deal in my opinion. The non-Lite S31 has power monitor of watts, amps, line voltage, kwatts used & cost (with rate entered), timer, time schedule, and repeat timer. These additional features are only accessible from the eWelink app.

Gotta love this vendors principle of remaining hacker friendly. Litterally 5 minutes to take apart hook up with a flashkit and get it running Tasmota!

Works well to turn on and off any AC powered plug-in device. Integrates easily through eWeLink and Siri.

Exelente producto muy fácil de emparejar y buena calidad a un buen precio

Very cute

A plug requires to use my phone number? How safe they can guard my info？!

I have no issue with Sonoff. I have been more satisfied with Sonoff than with the Amazon Smart Pulgs that I own. First: this package delivery was on my porch instead of Amazon Key inside the safety of the garage when I was out of town. Second: Upon opening the Amazon package, I found the Sonoff box had been opened (see photograph) and apparently the Sonoff device had been compromised. I returned this Sonoff smart plug. 5 Stars for Sonoff, 0 for Amazon for the delivery and apparently used and compromised product.

Wanted a couple more smart outlets for Home Assistant and ESPHome.. Easy to reflash these. Nice product

Excelent product ,i have one fan working with Alexa !!
