    • Easily to flash tasmota or esphome
Size: S31 Lite 4-Pack
Great cheap Wi-Fi outlet. Easy to open and flash the esp8266 with something else. I do wish it was not as tall, as I can’t plug this into my outlet with USB Cs in the center.

    • Beware: Only 2.4g NOT 5g useable
Size: S40 Lite 2-Pack
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.

    • Flashing Tasmota (for Home Assistant etc) - Some tips
Size: S31 Lite 4-Pack
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!). There's 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 isn't 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 don't 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. That's it! Future updates can be done OTA. ... show more

    • Not Zigbee compatible
Size: S40 Lite 2-Pack
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. ... show more

    • these things are great
Size: S40 Lite 2-Pack
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 they're 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 that's 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. It's nice that they're great, but they're also available at bargain prices. Cheap thrill. ... show more

    • QR Code to network this device
Size: S40 Lite 4-Pack
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. ... show more
