Shelly Pro 3EM is a Wi-Fi-operated DIN-mountable 3-Phase Energy Meter with Wi-Fi, Bluetooth, and LAN connectivity. With active energy measurement accuracy of 1%, Shelly Pro 3EM can be used to monitor the consumption of you home or apartment at an unbeatable price (much cheaper than smart meters). You can install it directly in the electrical panel of your house or apartment.
It connects with Zerofy through a WiFi connection and the cloud. It features 60 days of on-device historical data with a 1-minute resolution for each phase.
The device works by just laying clamps around the three main phases of your house/apartment, which allows it to measure power by induction.
Besides measuring your home's energy use, you can also use it to measure any home appliances, electric circuits, and office equipment individually.
