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

Very easy installation using the ewelink app, and easy linking to Alexa.

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.

You have to download the welink app. Not a fan of apps bc I use home assistant but it is what it is. When you set it up, look at the top for wifi, not bluetooth. Save you a few minutes of being frustrated. Works fine with Alexa, google, and smartthings. Easy integration.

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

Easy to open up and put tasmota on. Also leaves room for second plug. Great sonoff smart switch.

Works great with Tasmota! Love it.

Sumamente sencillo de instalar y configurar con Alexa, una configura dos, funcionan a la perfección, hyper recomendado

Even with the new UL listing they kept the WiFi portion the same so it is easy to flash with open source firmware. Super easy to open as it is not glued, all held together with screws. Rare to see that with smart plugs!

Bad advertisement of the product showing two but actually one comes in the package. Advertise one and sell one that it case close.

Fairly easy to tear apart, solder wires between your FTDI, and flash. No app required, MQTT and away you go. I bought a slew of these to replace the Etekcity branded VSync switches I had. We had an internet outage that lasted about a week and NONE of my automations worked, so I bit the bullet and moved as many of my switches over to something that didnt require internet access to function. Home Assistant and MQTT with Tasmota for the win.
