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

Es excelente y cumple a la perfección con su función. Evita que me levante de la cama.

I bought several of these specifically to control via an Arduino making HTTP REST requests to a server running doganm95/ewelink-rest-api-server. AWESOME way to customize without needing to swap out the firmware while still being able to use the eWeLink app.

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

Enclosure design is excellent for getting access to innards to flash custom firmware (Tasmota in my case). Not glued together but held together with snaps and screws. Build quality is good. Did not use stock software to control with Alexa but flashed firmware for local control (device does not “phone home” to China. WiFi reception is strong with the ESP chip (stronger than many comparable devices). So far, very pleased with design and results. All together, I’ve purchased 8 of the S31 (both Lite and EM versions) and they all work (some other brands were somewhat hit or miss). Good QC.

Great for high amperage devices. I wanted a smart plug that could handle 15 amps to control an electric heater with Alexa. This fit the bill.

I wanted to use this for bedroom light, which I can shut off from cellphone from bed, and start-on by toggling the wall switch the next day (by setting default-power-restore status = on in the setting). Working great!

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

Got these because they are easy to open and easy to flash with Tasmota so I dont need to go through Sonoff servers to control my lights. They arrived on time, were easy to get working and as I type this, they are controlling lamps in my house controlled by a Raspberry Pi running Node Red over MQTT while I am out of town. So far, I am a happy camper.

I worked at it a long time!

I accidentally ordered this version (the lite, which doesnt include energy monitoring) but was still much more convenient than than sonoff basic normal use due to the integrated plug. PLUS tasmota is still easy to install
