Battery Data #2

Closed rafaeluriarte closed 2 years ago

rafaeluriarte commented 2 years ago

I was trying to retrieve the battery percentage but I could not find the data in the "plant_data". It shows only if it has the battery ("existEnergyStore") but not its charge. Do you know if this info is available? In the web interface it is...

Hi @rafaeluriarte,

I believe that the charge (for the complete time frame) is stored in chargePower. That's where the web interface's graph seems to be getting the data from.

I've updated the get_last_plant_data function to also return this value.

Please let me know if it works as expected!

Thank you very much for the effort. Unfortunately, I don't think it is the right variable:

It says:

Last battery charge at 2022-04-29 21:40: 0.0

But I am at 96%

Any idea?

If it may help, inspecting the page I found this:

https://region02eu5.fusionsolar.huawei.com/rest/pvms/web/device/v1/query-battery-dc?dn=..........

the result is long but contained:

"{},"id":230320463,"latestTime":1651261514,"name":"[Module 1] [DC/DC] SOC","realValue":"96.0","unit":"%","value":"96.0"},"

Thanks!

Hi @rafaeluriarte

Since I don't have a battery myself, it took a while to figure out. The data for this diagram is part of the energy flow.

I've added a function to get the complete data of this diagram:

energy_flow = client.get_plan_flow(plant_id)

It's currently only on GitHub since I still want to add some nicer functions to process this data structure.

Thanks a million, it works like a charm!

The data structure is a bit strange but we can get the battery percentage with battery = energy_flow['data']['flow']['nodes'][4]['deviceTips']['SOC']

If you need some help with the dev, just let me know
