SONOFF S31 WiFi Smart Plug with Energy Monitoring, 15A Smart Outlet Socket ETL Certified, Work with Alexa & Google Home Assistant, IFTTT Supporting, 2.4 Ghz WiFi Only (2-Pack)

Estos enchufes solo funcionan a máximo 2 metros del router. Más allá no tomarán señal de wifi. Tengo unos más baratos y toman señal hasta 50 metros, una decepción los eschufes sonoff, literalmente solo funcionan al lado del router.

2 out of 4, S31 WiFi Smart plugs failed to stay on after 3,weeks. Trying to contact seller for replacements.

Pretty good, but kinda bulgy. Still good

I bought this device pack to monitor my servers power consumption. I got the package today. The setup was a bit confusing between Quick Pairing Mode and the Compatibility Mode. Lesson learned: Make sure your smart phone is pre-connected to 2.4 GHZ WiFi network. Otherwise quick pairing will not work. Once configured there is not much you need to do, other than naming the device and your room(s.) Right off the bat I have two complaints: 1. The big off switch on the App turns off the device with no prompt. A prompt, are you sure, would be very nice. 2. WiFi network requirement is for 2.4 GHZ. Granted, I do not need the speed but modern 5 GHz routers provide a better range as well. Other than that, for now, I like the device. I can monitor the power consumption in real time, which is what I was looking to do.

The appeal to this model is the ability to open them and hack them - great for automation. They didnt play nice with my router. 2 of the 4 kept going offline and I had to reset them to get them back.

Pros: Flashable Affordable Easy to use Compatible with Amazon Alexa, Google Assistant, and IFTTT Power monitoring feature Cons: Too big it cover 2 gauge outlets Not as fast as some other smart plugs Does not support 5GHz Wi-Fi To flash a Sonoff S31 with Tasmota, you will need the following: A Sonoff S31 smart plug A USB to TTL adapter A micro USB cable A computer with a terminal emulator Once you have gathered your materials, follow these steps: Disconnect the Sonoff S31 from power. Open the Sonoff S31 and expose the PCB. Locate the GPIO0 button and the TX and RX pins. Connect the TX pin of the USB to TTL adapter to the RX pin of the Sonoff S31. Connect the RX pin of the USB to TTL adapter to the TX pin of the Sonoff S31. Connect the ground pin of the USB to TTL adapter to the ground pin of the Sonoff S31. Connect the 3.3V pin of the USB to TTL adapter to the 3.3V pin of the Sonoff S31. Connect the USB to TTL adapter to your computer. Open a terminal emulator and set the baud rate to 115200. Enter the following command to enter bootloader mode: Press the GPIO0 button and hold it down. While holding down the GPIO0 button, plug the Sonoff S31 into a power outlet. Release the GPIO0 button after a few seconds. The Sonoff S31 should now be in bootloader mode. Use the terminal emulator to upload the Tasmota firmware to the Sonoff S31. Once the Tasmota firmware has been uploaded, the Sonoff S31 will reboot. The Sonoff S31 will now be running Tasmota.

Pros: Small footprint that would allow you to install two on a normal single gang outlet. Seem to be well-built, a step up from the no-name stuff of dubious origin and attention to electrical code/safety. EXTREMELY easy to disassemble and flash Tasmota/ESPHome if thats your thing. Integrates into Home Assistant easily, exposing Energy Consumption history, Wattage, Apparent Power, Reactive Power, Power Factor, Voltage, and Amperage. Cons: Ive ordered five units; (four S31 and one S31 Lite) over the last two months, and only one out of the five (the S31 Lite) showed an actual UL Listed badge. (My S31 circuit board design and components look identical to the UL Listed version pictures posted online, so Im not worried from a component/build quality standpoint, but a UL certification would bump this up to a 5-star product.) The form factor will block adjacent outlets if using on a normal power strip/surge protector/UPS. The mini 1-ft extension cords help for this use case

Easy to pair and get it working. Alexa, lights on, Alexa lights off! This plug is very handy! I am going to use it for my Christmas tree when its time! Looking forward to not having to struggle with the outlet each night.

These are great plugs that provide a great deal of power usage info, are easily flashed to Tasmota (for local home automation), and are well manufactured. Have at least 8 in the house now, purchased over many years, and they keep working great.

I used tiny spring clips on a USB cable to connect to the board inside and flash Tasmota. Worked great! Unlike the KMC 30153 where they changed the underlying SOC chip (so you never know what youre getting), these have real Espressif 8266 chips in them.
