          This integration stopped working completely, failed to load when I updated to the latest version of the integration today. Don't think it has anything to do with the meross device firmware, I'm on hardware 8.0.0, firmware 8.3.5, but restarting HA throws the following early errors while trying to load the new version during restart:

Home Assistant 2023.10.0, was running integration version Moonlight.2.2 (5.2.2) upgraded to Moonlight.3 and restarted HA

Probably a different issue from yours though, if your integration loads but then fails on one device type.

@pbrooks29: yep, totally different issue so I'll open a new one. I guess you've encountered a problem while downloading the update and your files are 'corrupted'. It happens some times and various users had this kind of 'failed loading' right after an update. I don't know why and where this happens but it's usually fixed by redownloading the component.

Ar at least I hope so ;)

Same problem, return to version 5.2.2.

I guess I've found the issue, likely related to your HA still running on python 3.11 (see #477) This 'backward compatibility issure' has been fixed a few days ago and the current pre-release (v5.3.1-alpha.1) already has it patched. To enable download of pre-releases in HACS there's an option to enable beta repositories...else it will take a week or so before finally publishing the next 'official' 5.3.1. Else, in any recent HA release (those with python 3.12) 5.3.0 should work.
