DEYE SUN-(xx)-G03 lost connection after upgrade to 1.5

[hyneksuchodol]

Device disconnected after upgrade. Can't connect it back. Need to downgrade to version 1.4.3.. After install back old version every think looks good. I've seen multiple issues like this in several threads.

[pawelsn]

I do confirm.

Solarman 1.4.3 was working fine with Deye SUN-6k-G03. No updates anymore after update to v1.5.0

With v1.5.0 I have noticed in the logs: 2023-09-06 10:29:25.170 WARNING (SyncWorker_7) [custom_components.solarman.solarman] Querying [3 - 112] failed, [0] retry attempts left 2023-09-06 10:29:25.171 WARNING (SyncWorker_7) [custom_components.solarman.solarman] Querying registers [3 - 112] failed, aborting. 2023-09-06 10:29:53.880 WARNING (SyncWorker_1) [custom_components.solarman.solarman] Querying [3 - 112] failed with exception [error: unpack requires a buffer of 220 bytes]

I use "deye_string.yaml" for Deye SUN-6k-G03 device Integration started to work again after downgrade to 1.4.3

after upgrading the plugin (and restoring the custom config file)was no longer able to read out the value an generated lotś of errors like this:

home assistant solarman failed with exception [Illegal Data ValueError: The value contained in the request data field is not an allowable value

downgrading solved the problem

--- UPDATE ---

from https://github.com/StephanJoubert/home_assistant_solarman/pull/224 I can see that the converter should have been working with the provided deye_2mppt.yaml but in my case it also did not work

[oxynatOr]

its a dupe of #367

the reading registers are: 0x0001~0x007B (123) and not 0x0080 (128)

[andregoncalvespires]

same here to deye_4mppt.yaml

[leoheitor]

Same here... almost all parameters are in Unknown state

[ChristophCaina]

yes, I can confirm the same :-(

[Quellweg22]

Yes, Same here … :-( …

[oxynatOr]

as i say... its a dupe. pls join #367

[pawelsn]

Update to 1.51 do not solve the issue. To keep it functional I have to stay on 1.4.3

[pawelsn]

Is this issue being investigated, or it has been wrongly assumed to be fixed in 1.5.1 release?

I'm not sure. I'm using fw 1.5.7 and it's working well: https://github.com/dasrecht/deye-firmware/tree/main/0_D0002_18 - I even don't know 1.4.3 or 1.5.1
