Shelly 1pm plus consumption by minute

  • I have connected my shelly 1pm plus in front of water heater and try polling consumption from the device. I want to use aenergy.by_minute but it seems to be some wrong value or I don't understand how to use it. I have 1500W heater but the output says that by_minute the consumption is ~31791 mWh /minute under load. It doesn't make sense or am I missing something? Here is the json output
    "switch:0": {
    "id": 0,
    "source": "init",
    "output": true,
    "apower": 1448.6,
    "voltage": 227.2,
    "current": 6.314,
    "aenergy": {
    "total": 426.966,
    "by_minute": [
    6266.211,
    31791.498,
    31968.242
    ],
    "minute_ts": 1657353430
    },
    "temperature": {
    "tC": 55.6,
    "tF": 132.1
    }
    },


    Firmware version: 0.11.0-beta1

  • By_minute values state power consumption for the last three minutes

    Energy consumption by minute (in Milliwatt-hours) for the last three minutes (the lower the index of the element in the array, the closer to the current moment the minute)

  • I think this is realted to the current issue of power measurment with the 1PM plus.

    With firmware 0.10.3 it always calculates a unrealistic high power consumption.
