Shelly EM negative power when idle

    • Autor

    I have Shelly EM with two clamps: 50A and 120A. I noticed when there is no load, everything is idle, 120A clamp is showing 0W as it should but 50A clamp is showing between -1,8W and -1,3W constantly changing this number. It should also shows 0W because electrical device is not turned on.

    Can somebody explain and advise me how to recalibrate/offset?

    Hi I have nearly the same issue. When I`m switching in the app the output from the shelly randomly approx10 times (In my case there is no device connected) the value is jumping to 0W. Do you have the behavior?
