[Bug]: Unknown values for MIC X3

[the-real-mcarn]

Describe the bug

Plugin connects to the inverter correctly, though throwing a warning, and all values remain either 'Unknown' or just 0. Behaviour is since 2024.12.01 but I had not updated since the breaking changes HASS version 2025.1.0. Reverting to a previous version fixes the issue.

Additional context

The following solutions I tried without success:

• Restarted inverter & RS485 adapter
• Reconnected RS485 adapter
• Run without PocketLAN (v3) connected
• Restarted home assistant
• Reconfigured inverter in home assistant
• Removed and added the inverter back in home assistant

Reading the holding register 0x318 (0d792) returns 0x0000 in Open ModScan.
