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

There was no way to find the device’s MAC address so I was unable to connect it to my wifi. Not very accessible

Working well as expected. No issues !

First it took a very long time to sync, then when I moved the device to a different outlet (closer to the router) to failed to sync. Sending back and getting from a different company

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

Very easy installation using the ewelink app, and easy linking to Alexa.

Originally thought these were a good value, until today when I unplugged one outlet to move to a different location and since then, it will not power back on. It will flicker on and right back off when connected to a light and you literally hit the outlet box. This leads me to believe it has faulty wiring inside which could definitely be a fire hazard. Beware

These work great for flashing Tasmota, but you need to be familiar with the flashing process. Here are some tips: - Highly recommend those rubberized Mini probe test leads to clip between the board and FTDI flasher to avoid the annoyance of doing a hard solder just to flash the device. - Any basic FTDI-type USB flasher will work, just make sure it can provide 3.3v (make sure to set it to 3.3v before connecting!). Theres a cheap FT232RL $5 one on here--make sure you have any requisite USB connector for it (mine needed the uncommon USB mini adapter). - Opening the Sonoff isnt terrible difficult, use a spudger or mini flathead screwdriver to pop off the grey cap on the side facing the plug. Remove the white sliding things, and be gentle doing the 3 screws since they strip easily. - Grab the latest tasmota.bin from Github. There are multiple tools that can flash it, I used ESPHome Flasher. - Flashing: 1. Connect GND, RX, and TX probes between the Sonoff and your FT device, but dont connect VCC just yet. GND goes to GND, but RX goes to TX and vice versa! 2. Plug in FT device to computer. 3. HOLD DOWN button on the Sonoff device and connect VCC--if your FT device has LEDs they should flash but Sonoff should not. 4. Refresh ESPHome Flasher and it should detect your device on the USB port. Load the firmware .bin and flash it. 5. If successful, put the Sonoff back in its housing and plug it into an outlet to test. Use your phone to connect to the temporary AP so you can give it your wifi details. Thats it! Future updates can be done OTA.

Works really well as is. Can be a tiny pain if you want to use them on a quad outlet as it will block its neighboring outlet. but to be fair thats almost all smart switches. Other than that, solid build and operation. Love the fact it can be dissembled and flashed if you desire and have the knowledge to do so.

I read somebody else’s review that said it worked with 5 G however, I was not able to make it work with mine. My equipment is supposed to be able to adjust down to 2.4 g. THIS IS NOT THE FAULT OF THE MANUFACTURER because they clearly state that it is for 2.4 g.

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