Exposing wNow from storage (battery) entity in production.json?

[jackson-tim]

Looking to expose the wNow field from storage here to view the input/output wattage into/out of the batteries:

https:///production.json?details=1

e.g.:

  "storage": [
    {
      "type": "acb",
      "activeCount": 0,
      "readingTime": 0,
      "wNow": 0,
      "whNow": 0,
      "state": "idle"
    }
  ]

It's confusing sometimes to see high "consumption" wattage when the batteries are charging, and showing this value would help (and being able to do something like summing it with the overall consumption since it shows negative when charging, positive when discharging, etc).

I've poked through the reader, etc some but don't see exactly where this would be the easiest to add.

I have a system where the battery info comes in through the /ivp/ensemble/inventory endpoint and not the /production.json endpoint. I would need someone with production.json to work on this.

[jackson-tim]

I can help with data/samples/access if it'd help. Let me know what data/help needed and I'll get it to you.

Actually looking, I see all of the individual battery information under /ivp/ensemble/inventory but I don't see the input/output power to each battery there.

Yeah, the /ivp/ensemble/inventory endpoint does not give input/output. I calculate the Battery Energy Charged and Discharged entities by taking the difference between the two most recent values of Total Battery Capacity. Does that give you want you need?

I suppose I can also calculate watts from the watt hours of the Battery Energy Charged/Discharged and elapsed time.

The ivp endpoint doesn't, but the production.json does (even when the rest of the stats is in the ivp endpoint).. I've just worked around it for myself by adding CTs to the battery panel and to the load panel to view input/output there.

I get wh, etc from the batteries via /ivp/ensemble/inventory just real-time is in production.json in the storage bit..

I found an endpoint exposing input/output power: https://envoy.local/ivp/ensemble/power

    "devices:": [

            "apparent_power_mva": -227000,
            "soc": 82
        },
        {
            "serial_num": "xxx",
            "real_power_mw": 0,
            "apparent_power_mva": 0,
            "soc": 14
        },
        {
            "serial_num": "xxx",
            "real_power_mw": -92000,
            "apparent_power_mva": -92000,
            "soc": 93
        },
        {
            "serial_num": "xxx",
            "real_power_mw": 0,
            "apparent_power_mva": 0,
            "soc": 8
        },
        {
            "serial_num": "xxx",
            "real_power_mw": -27000,
            "apparent_power_mva": -27000,
            "soc": 94
        },
        {
            "serial_num": "xxx",
            "real_power_mw": -88000,
            "apparent_power_mva": -88000,
            "soc": 100
        }
    ]
}

pwer is in mW soc is the battery percentage power_mw is negative when charging
