I’ve recently started experimenting with the Shelly 3em energy monitor, and I must say, it’s been an enlightening experience! After setting it up behind my main electricity meter, I was curious to see how it would compare to my existing energy readings. However, I noticed something intriguing—the Shelly 3em was showing double the energy consumption compared to my meter. To dig deeper, I connected a clamp meter to verify the readings, and it consistently showed about half of what the Shelly was reporting across all three phases. This discrepancy was puzzling, especially since there’s no solar energy being fed back into the grid.
After some research and reaching out to the community, I discovered that this issue might be related to how the Shelly 3em calculates energy usage, particularly in multi-phase setups. It seems that the device might be summing up the currents from each phase without properly accounting for phase differences, leading to inflated readings. While this hasn’t hindered my ability to monitor energy consumption trends, it’s definitely something to be mindful of when interpreting the data.
On a more positive note, I’ve been impressed by the Shelly 3em’s integration capabilities with my smart home ecosystem. Pairing it with my existing Shelly devices has streamlined my energy monitoring setup, and the detailed statistics it provides have been invaluable for optimizing my energy usage. For instance, I’ve been able to identify peak consumption periods and adjust my habits accordingly.
If anyone else has encountered similar issues or has tips on fine-tuning the Shelly 3em for more accurate readings, I’d love to hear about your experiences! It’s always great to learn from others in the community.
