Exposing wNow from storage (battery) entity in production.json? about home_assistant_custom_envoy HOT 6 OPEN

@briancmpbll

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.

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

{
    "devices:": [
        {
            "serial_num": "xxx",
            "real_power_mw": -227000,
            "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

software version on envoy is D7.6.111

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.

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.

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..
