Can't initialize integration after 2024.4 about nilan HOT 8 CLOSED

Sorry, I don't have time to look into this right now. Could not fix it easily, there is some issue introduced to the modbus wrapper on HA after making it async.

I would hold on updating/roll back for now.

@AdamGrumlik - see viesta's comment above.
He's the author of the integration, is aware of the issue with 2024.4 but doesn't have time to look at this at the moment.

Best advise at this point is to roll back for now if you've already updated and the Nilan integration is required. 👍🏻

Same, please let me know if I can provide any logs etc that could help. Thanks!

Same here. I get a timeout when the integration attempts to connect to my Modbus gateway.

2024.4.0 Integration not working:(

from nilan.

I think I've found the issue,

HA ModbusHub is now fully async:
home-assistant/core@7cba34b

and thus the success = await self._modbus.async_setup()(device.py) call does no longer wait for the connection to be established.

in my local workaround i've added a await asyncio.sleep(10) right after to get it running again for now.
Though this is far from a beautiful solution it works for now.

(+ I've added the await before await self._modbus.async_close() to avoid another error)

Great! Can you make a pull request?
