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 bad experience. I did everything the manual told me to do. I downloaded the application and I also followed the instructions step by step but I never managed to pair it, it does not even appear in the app.

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.

easy connect ! easy to use app!

Works great with Tasmota! Love it.

Works well as is, but once Tasmota is flashed to it, its functionality is increased ten-fold.

Smooth as glass, to set up and works flawlessly.

This is a lite unit, and does not have the full functionality of the s31 switch, but has most of the price.

If you are not persistent, you will not easily connect this device to your wifi network. What I found works best is to scan the QR code on the device, and VOILA, the magic happens. Going the more conventional route by using the tradtional methods to add this device to your wifi network will result in unneecssary frustration IMO - I speak from experience.

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

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