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

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

Facil de usar, muy simple

This hooks up to my Google home nest and Alexa. Simple to install and control. Im buying more.

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.

I got my first Sonoff switch a few years ago. Had to wire it up myself, but it worked well. These S40s are terrific. Just plug em in. The connection is established with Bluetooth, and from then on theyre connected to the internet through the local router. Using eWeLink, you can turn things on and off in your house from anywhere in the world. Several years ago, it was disappointing that eWeLink was a phone-only application. But thats fixed. You can now have the app on your computer to control these guys as well. The S40s are dead-nuts simple to use. Once programmed, you can unplug them, and plug them in anywhere else in the house without changing anything. Its nice that theyre great, but theyre also available at bargain prices. Cheap thrill.

Works great with Tasmota! Love it.

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

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.

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.

Worst buy ever... I thought I was getting a great deal with the 4 pack... Wrong had to return them as they would not pair. Im in IT so I know how to pair... Junk as I see it on my part...
