Fronius Smart Meter missing after adding BYD Battery

[LDprg]

The problem

I have a Fronius Gen 24 with two Smart Meters and a BYD Battery. The two Smart Meters were working fine until I added the BYD Battery recently. One of the two Smart Meters suddenly disappeared (other one and the battery working fine).

On the Fronius Gen24 itself everything is working as expected.

What version of Home Assistant Core has the issue?

core-2024.6.1

Hi 👋! Can you add some information about your system and a diagnostic download?

[LDprg]

@farmio I cant download diagnostic of the whole fronius integration since clicking the download button doesn't start any download. I tried different browsers, but no success. However the independent devices work.

But here are my Fronius specs: Fronius Gen24 10 Fronius Gen24 4 (because the Gen23 10 couldn't handle the produced power on it own ) 2* Smart Meter TS 65A-3 (one for Battery and one for Heatpump) BYD HVM Battery 11kWh

Here are the device diagnostics (The smart meter from the heatpump missing, since as mentioned it isn't available since adding the battery) config_entry-fronius-d81e9a6045d9375078f2cfeb03976464 (2).json config_entry-fronius-d81e9a6045d9375078f2cfeb03976464 (1).json

Oh, there seems to be a bug with diagnostics downloads currently https://github.com/home-assistant/frontend/issues/21061

The second batch of diagnostics you uploaded seem to see 2 meter devices. I can't see (it's redacted) if they maybe have similar serial numbers - which would be odd, but would explain why only one is seen.

I mean they have been working before in homeassitant. And in the Fronius UIs both Smartmeter work as expected. Just they that one is not visible.

Also I checked, I accidentally downloaded and uploaded the diagnostic from the smartmeter that works twice. So they are actually the same file and smartmeter. I couldn't download the diagnostic of the not visible Smartmeter because well it is not visible and therefore the menue is missing.

I think I have the same issue, Gen24 with BYD battery. Single Smart Meter TS 65A-3. Smart meter data not visible anymore in HA after upgrade from 2024.3 to 2024.6.2

@farmio I got the problem solved. The issue is that when adding the battery the integration resets all the names. My first smartmerter had the default name, but the second was renamed. So the second smartmeter got reseted and had the default name with a number afterwards, Because of the similar names I didn't noticed that it still existed.

The Integration shouldn't rename Smart Meters that didn't change when reinitializing the device because of another added component.

[farmio]

I have no explanation for why that happened. The changed name is stored in HAs internal device registry entry - which is linked to the device by its serial number. So if you didn't remove and re-add the integration these changes shouldn't be touched by adding another device.
