Review: The monitoring I need. I'll be buying more Shelly monitor. - So easy to install. Easy to use. The Shelly Smart Control app works well. There are other ways to monitor, but I haven't tried any others. I really like that I could install this at a convenient location not in the main breaker panel. I needed a DIN rail enclosure, but that was easy to get. I'll be buying more Shelly monitor.
Review: Simple with many options - Very easy setup either ethernet or wi-fi. Current readings and voltages match closely with my Fluke DMM. I am still experimenting with all the available features. The desktop and Android apps have both worked well. If you are interested in power consumption with the ability to control the load I would consider this item.

## Features

- Shelly Pro EM 50A is a Wi-Fi energy meter with contactor control and LAN connectivity.

### ⭐⭐⭐⭐⭐ Works wonderful in Home Assistant
*by X***M on August 2, 2025*

Works great with Homa Assistant. Have 4 of these 2 are on wired ethernet and 2 on Wi-Fi. Not 100 percent accurate but very close. Wish there was a offset or calibration process. Note the voltage input is very small and somewhat difficult to connect. Home Assistant immediately identified the devices on the LAN and came online without issues. Entities include power W, Aparent power va, current A, Power Factor, Total active energy kWh, Total active return energy kWh, Frequency Hz, and Voltage. Also can reboot the device from Home Assistant, control the relay dry contact and update the firmware in the HA interface.
