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

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

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

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.

Its not 220v

Very cute

Facil de usar, muy simple

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

It is very easy to use and when you add it to the app it automatically adds to alexa too

easy connect ! easy to use app!

I have been using Sonoff sockets, S20s and S31s, for a couple of years. I have about 10 of them currently operating in two houses, none have failed. I do reprogram them with the Arduino IDE. They use an ESP chip from Expressif which are very reliable. So this a rating for the hardware, I have never used their cloud service or software.
