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

I worked at it a long time!

While this product works to control objects just as well as the Original S31. BEWARE, it is the S31 LITE which means it will NOT do any power monitoring for you. It is just a small switch. Looks wise on the exterior, it is indistinguishable from the power monitoring version. In the eWeLink app, it will look like any non-power monitoring switch you may have like an S20 or S26.

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.

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.

First smart device that Ive ever bought that I couldnt get to connect to my network.

Was faulty returned I have other sonoff items and like so im sure just a bad one return was easy

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.

This item does what it says. Excellent!!

Works well to turn on and off any AC powered plug-in device. Integrates easily through eWeLink and Siri.
