I mounted this inside an wall outlet to monitor power usage of a PC. Initially, it would not automatically reconnect to Wi-Fi after a grid power failure. The only way to reconnect, was to open the wall outlet and push the reset button on the Sonoff. But, the latest firmware update seems to have fixed this issue and it's been working great.I use this Home Assistant.

It is a great improvement over the R2, which itself is great and I have a dozen or so of. Back in Nov 2020 I sent itead a feature request to use the ESP32 so that OTA upgrades could be done(check), make it a bit smaller to work in their IP66 waterproof box(check), and add the ability to access more of the GPIO pins on the ESP32 (sadly, no check mark here). Although the case has a bit of glue on the 4 tabs holding it together, it can still be hacked by opening, soldering leads to the TX/RX/GND/3V3 pins and pressing the button when powering up. I only used it for a few minutes with stock software, but after adding to eWeLink, Alexa recognized it and I switched it out of blinds mode to regular mode. and played for a minute... then I cracked it open, connected up a CH340 USB dongle, and wrote some custom firmware to it and was able to use the following:GPIO27 relay1GPIO14 relay2GPIO13 status_ledGPIO0 buttonGPIO32 switch 1GPIO33 switch 2I would give it 5 stars if they made the other GPIO accessible via pin-pads or thru-holes:1-wire and resetGPIO 5SPI for RTD amplifier:GPIO 18GPIO 19GPIO 23CS for RTD amplifierGPIO 12GPIO 15GPIO 25GPIO 35

I used this product for controlling electric heat relays and it works great. The control software is easy to use and integrates with many of the popular home automation systems. I have used SONOFF products for several years in many different applications and have had no issues.

El dispositivo funciona excelente, solo tener en cuenta que, cuando la carga es un motor la corriente máxima es de 1A, solo es 10A para cargas resistivas.

Great deviceI use it to control the curtains at home;1- To open/close as needed2- Close all curtains when I go out in one button3- Timers; like to open bedrooms curtains (partially) with the alarm. Also close them in the eveningI didn't need to call the support nor did I use it with Alexa (so far) so I can't rate itThe only improvement I would like to see if they can reduce the "thickness" of the device as in Jordan (where I used them) the electric boxes are smaller and it is hard t place them inside (I had to add depth or install the device by the curtain motor (in the over windows boxes), but this should not be an issue in USA/Canada and Europe

First SONOFF device in my smart home. All of my previous devices were SmartLife App compatible. So I needed to install a new app to manage this.This little device in addition to controlling my shutter motor also is monitoring energy usage. So I now have a way to know how much operating my shutter cost for me.I bought one, but I'm ready to buy the rest to control all of my shutters.
