only reconnecting after inverter restart

[Zef-X]

Version of the custom_component

0.0.26
SMA Tripower X 25 firmware 03.06.19.R

Configuration

Inverter not active on 192.168.20.103:502
Failed to connect to 192.168.20.103:502 slave id 126

Describe the bug

After restarting HASS or restarting the integration, SunSpec wont connect to Inverter.
Stoping and starting Modbus Server or replugging Ethernet dosnt help.

When restarting Inverter, I get data as intended without problem.
But again, when I wanna change the config SunSpec tells me it can't connect to Inverter even though data is recieved and everything works as intended.

Same. Reverted to 0.0.25

Temp fix for me was downgrading to 0.0.25 and replacing sensor.py with sensor.py from 0.0.26 (Constants in use by 0.0.25 get removed Jan 2025).

Suspect "Bump pysunspec2 from 1.0.8 to 1.1.5" is the source of this new issue.

That worked for me as well. Thank you for pointing me in the right direction @SmileyMan

I see the error "Failed to connect to host (hostname):502 slave 1 - Inverter not active on (hostname):502".

Edit: After removing this integration and installing again, it does not connect anymore. I have used 'mbpoll' utility on another computer to verify that the modbus target is responding to queries. It seems that sunspec integration is just broken about making connections to network hosts and the logs do not show anything more useful to say.
