Works great after firmware update

S. KinkeadJanuary 15, 2025✓ Verified purchase

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. Read more

Works great as designed, however no DIY mode and not as hackable as the R2

Michael C.June 15, 2021✓ Verified purchase

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 relay1 GPIO14 relay2 GPIO13 status_led GPIO0 button GPIO32 switch 1 GPIO33 switch 2 I would give it 5 stars if they made the other GPIO accessible via pin-pads or thru-holes: 1-wire and reset GPIO 5 SPI for RTD amplifier: GPIO 18 GPIO 19 GPIO 23 CS for RTD amplifier GPIO 12 GPIO 15 GPIO 25 GPIO 35 Read more

Great product for home automation.

MN RodDecember 28, 2024✓ Verified purchase

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. Read more

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. Read more

Great Device

Perit HakuzAugust 22, 2022✓ Verified purchase

Great device I use it to control the curtains at home; 1- To open/close as needed 2- Close all curtains when I go out in one button 3- Timers; like to open bedrooms curtains (partially) with the alarm. Also close them in the evening I didn't need to call the support nor did I use it with Alexa (so far) so I can't rate it The 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 Read more

Easy to install, working as it should.

JR SueroSeptember 17, 2022✓ Verified purchase

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. Read more
