I realize this version of HB is beta but this appears to be related to an underlying change in the way HB handle plug-ins so FYI...
Since upgrading to the beta the logs are filling with:
[2/15/2021, 8:09:30 AM] Received error for the plugin 'homebridge-aqualinkd' from the characteristic 'Model': Error: [Model] characteristic must have a length of more than 1 character otherwise HomeKit will reject this accessory. Ignoring new value.
