Excelente producto

### ⭐⭐⭐⭐⭐ Works great after firmware update
*by S***D on January 15, 2025*

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.
