template: huawei-dongle-powersensor 0 values of battery SOC and charge/uncharge power

[annotationshacker]

Describe the bug

Hi Guys, first thanks for your terrific work in this project!
I hope it's fine to open here this case.

The battery values (charge/uncharge, SOC) of my meter are every times "0"(not null, only 0).
My hardware:
Huawei Luna battery, a SUN2000-KTL-M1 inverter and the dongle using Modbus TCP to get data.

Firmware:
Dongle: V100R001C00SPC133
Inverter: V100R001C00SPC155
Battery Software & Firmware: V100R002C00SPC119

I'm also using HomeAssistant, where I can see successfully those values of the battery using the Huawei Solar Integration by https://github.com/wlcrs.

Do I use the false template or there anywhere else an error in my config?

Thanks!
Donald

Hi @annotationshacker,
I think I have a very similar issue with my Huawei setup and I have still no solution for it.
Could you check your battery details here:
https://region04eu5.fusionsolar.huawei.com/pvmswebsite/assets/build/index.html#/view/device/NE=35228666/battery/details
I have one battery but it shows me 2 ESU on that page.
ESU 1 does not contain any values while ESU 2 does show the correct values. It seems like evcc is pulling the data of ESU 1 but not ESU 2 and I have no idea how to change this.

Hi @fzzybllz,
interesting ..
I only use the fusion app, never the webfrontend.
I only have one ESU, but named ESU2.
I can't find any ESU1.
May be that's the cause that the template always looks for ESU1, that don't exist.

Add storageunit: 2 to battery meter or use
evcc configure --advanced to build a new config file by answering the advanced parameter settings.

[fzzybllz]

Nice, thanks a lot. That solved my issue with ESUs.

[annotationshacker]

Works also for me.

Thanks for the hint!
