Shelly 3EM-63T Gen3 is a smart energy meter for monitoring three-phase systems or three single-phase circuits. It features 4-quadrant measurement, real-time data with optical pulse indication, Accuracy Class B, photovoltaic system support, and easy integration into smart home or professional setups.
Precise Measurements & Data Logging: Measures voltages from 220-240 V AC and currents up to 63 A per phase, with built-in data storage for up to 7 days at 1-minute intervals
Home Energy Management – The device helps homeowners monitor and optimize energy use with real-time insights into appliance or circuit consumption. It identifies high-usage devices, supports efficient scheduling (e.g., for heating/cooling), and enables local automation to cut power during peak times-reducing costs without sacrificing convenience.
Cost Optimization for Businesses – The device lets businesses monitor energy use across three circuits, enabling precise tracking of machines, departments, or processes. This helps identify inefficiencies, allocate costs accurately, and reduce overhead through data-driven operational improvements.
Solar Energy Monitoring – Ideal for PV system users, the device tracks both energy production and consumption to ensure peak solar performance. It helps align usage with generation, enabling tasks like EV charging during peak sunlight to reduce grid reliance and maximize renewable energy benefits.

Pro level current meter at a bargain price!
Fantastic current meter! The bonus is built in Ethernet! Small size will fit in tight spaces and easy install.Great function, except for some reason data download is not working right. There is also connection point for 1 more CT, but last I checked it is not sold separately. AND I wish there was short piece of DIN rail in box.

Works wonderful in Home Assistant
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.

Works perfectly and easy to install / setup
Excellent product and easy installation. Allows me to monitor a remote condo and keep tabs on the HVAC and power consumption. The app is well polished and provides all the information and control you would expect with this device

Works great when integrated with HomeAssistant
Great product generally, although there are a couple issues with the REST API if you’re trying to write your own code to control it. Bad SSL certificate for https, and it rejects https requests anyway with a 443 error, yet it also does a strange redirect to https when you call http on port 80. I tried updating the firmware but issue remains. Integrated with HomeAssistant and called that API instead, which works great. Would be 5 stars if not for the odd issues with restful calls.

Comes with three 120A current transformers
This comes with three 120A current transformers. My Home Assistant software found it easily.

Fácil instalación en el cuadro eléctrico, viene con 2 pinzas amperimétricas. Yo no tengo mas productos de Shelly, así que no puedo opinar sobre la integración domótica. Lo uso para el monitoreo de las placas solares. La app te permite monitorizar en tiempo real el consumo de energía de la vivienda, la producción de las placas solares y el volcado/consumo de red o baterías. Gráficas diarias, por mes, año, etc. Funciona con la wifi de casa y te da información suficiente y bastante exacta sobre tu consumo energético en cualquier momento y lugar. Solo encuentro a faltar en la app, disponible en apps de otos medidores (y otros precios), el diferenciar el consumo por electrodoméstico. De momento sin problemas de funcionamiento y satisfecho con la comprs.
