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

would not turn on using any plug in the house

August 2021, the pin pads are easily accessible, no trouble flashing Tasmota to it. Disassembly was easy and non-destructive. Great build quality and extremely responsive. I’m running 6 of these, never had a problem.

Cant leave a bad review because they seem like typically Sonoff quality and it was my mistake, just know they cant be flashed to Tasmota. Go for the S31 version if you want that instead

Moving to a fully local control system and these fit right in. I flashed them with ESP-Home and dropped them into Home Assistant with no issues.

Use caution when ordering these. I didn’t realize there were two versions of the S40 Lite, Zigbee and Wi-Fi. I bought this version by mistake, and while they’re returnable, I don’t have a UPS store near me and Amazon won’t provide a free return label for a pickup. The Wi-Fi version does not seem to be as well supported in home assistant, the add on provided for it only seems to provide a Lovelace card and not a proper device, so as far as I can tell so far it can’t be used in automations. The s40 version also can’t be flashed with alternate firmware, so it’s usability with home assistant is limited.

Very cute

Set up was easy with the Ewelink app and then connecting it with Google Home. They wont block above or below it

Working well as expected. No issues !

Facil de usar, muy simple

I read somebody else’s review that said it worked with 5 G however, I was not able to make it work with mine. My equipment is supposed to be able to adjust down to 2.4 g. THIS IS NOT THE FAULT OF THE MANUFACTURER because they clearly state that it is for 2.4 g.
