Excellent energy monitoring switch
I installed the Shelly 1PM to monitor my living room lights and appliances. The real-time power readings are very accurate and helped me identify energy hogs. Setup was straightforward, and integration with Alexa works flawlessly.

Great smart switch but needs some electrical skills
The device works perfectly and the app offers good control and energy data. However, installation was a bit tricky since I had to deal with wiring inside the wall box. Definitely not a plug-and-play product.

★★★★☆
Compact and reliable smart switch
This switch fits neatly behind my light switch without any hassle. The Wi-Fi connection is stable, and the ability to update firmware over the air is a nice touch. The app could be more user-friendly though.
