Review: Works great after firmware update - 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.

### ⭐⭐⭐⭐⭐ Works great after firmware update

### ⭐⭐⭐⭐⭐ Great Device
*by P***Z on August 22, 2022*

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
