I recently upgraded from the Shelly 3EM to the Shelly Pro 3EM and wanted to share my experience. Initially, I encountered a minor issue with the error message ‘EM (0) experienced an error: no load.’ After some research, I discovered that this was related to the power factor on one of the phases. The Shelly Pro 3EM handles this seamlessly, providing accurate measurements across all three phases. The integration process was straightforward, and the device has significantly enhanced my energy monitoring setup. I’m thrilled with the performance and reliability of the Shelly Pro 3EM—it’s a must-have for anyone serious about energy management.
