Problems since adding Hoymiles MS-A2

[Guruhugorune2]

Hi,

I added today the Homiles MS-A2 to my Homiles Account. Since than I have a bunch of new sensors from the plugin....but some of them seem to to work.
Example: solarH_xxx_bms_return as always the same value. In Hoymiles Cloud and S-miles Home the right Value is present

But what is the worse....the two real_power sensors are zero since I added the new device. I suspect the problem is because I didn´t conected the solar modules direct to the MS-A2 (because I want use in a other way) and so Hoymiles shows now Solar 1 (with zero because nothing connect to MS-A2) and my (old) System as Solar 2 (with the right values in Cloud, but not in the add-on).

Did anybody faces the same problem and has a solution?

regards
Markus

Hi,
I have the same problem ; real_power and power_ratio are always to 0
On Hoymiles cloud, I have Solar1 connected to MS-A2 with my solar panel, and Solar2 to 0

Have you an idea to retreive real_power data ?

Sorry I have no idea what you just wrote. I don't understand it.

I have simple instalation with uInverters and solar panels.

Since I connected my MS-A2 battery, I can no longer receive real_power data

As I wrote in first entry, when you add an Ms-a2 Battery to your system, the Inverter bulitin the Battery is now Solar 1 and current inverter turns to Solar 2 and the app only imports Solar 1 (to which nothing is connected in my case). The request would be to provide an entity for Solar 2 or add the value to real_power.

On my installation, my solar panels are connected to MS-A2 .
So , they are on Solar1 entity .
But without real_power data ....

I started to check with Postman ... If you have information about Hoymiles API, I take !!!

There are no information about API. You have to make full reverse engineering as it is written in README.

[daggerbzh]

Yes, I saw . But I think you have an unofficial document to explain API. I search and come back to you if I found something Le jeu. 19 mars 2026, 20:38, Cosik ***@***.***> a écrit :

@daggerbzh the same effect you will get with enabled debug logs, but if it used different endpoints it is a different story.

I connected my battery with MQTT to receive all datas in real time
