## Customer Reviews

### ⭐⭐⭐⭐⭐ ⭐️⭐️⭐️⭐️⭐️ Powerful Energy Monitoring with Flexible Connectivity
*by T***R on September 22, 2025*

⭐️⭐️⭐️⭐️⭐️ Powerful Energy Monitoring with Flexible ConnectivityThe Shelly Pro 3EM (120A) has been an excellent addition to my setup. I really like how it provides accurate, real-time monitoring across three phases, making it easy to keep track of power usage and efficiency. The data it provides is detailed, reliable, and gives me a much better understanding of where energy is being used.Another huge plus is the dual connectivity—both Wi-Fi and LAN options. Having the ability to hardwire it makes the connection extremely stable, while Wi-Fi keeps it flexible if hardwiring isn’t convenient. Setup was straightforward, and the integration with my system worked smoothly.Overall, the build feels professional-grade, the monitoring is precise, and I’m impressed with how easy it is to access and analyze the data. If you’re serious about energy management, the Shelly Pro 3EM is a great choice.

### ⭐⭐⭐⭐⭐ Pro level current meter at a bargain price!
*by C***E on July 12, 2025*

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.

### ⭐⭐⭐⭐⭐ Great product
*by D***A on July 2, 2025*

Excelente producto, sería ideal alguna versión en Zigbee
