From the HA logs (several occurrences):

Ok, I'll have to handle when it can't find the time zone. To clarify, it is detecting you are in the BST timezone? For my education is that British Summer Time? And what is BUI?

[davidgdlt]

Apologies for the late reply. It was detecting I was in British Summer Time as that's what was set in Home Assistant's Browser User Interface. The abuse of acronysms is just professional deformation :)
Thanks for looking into it!

I just updated to 0.3.8-beta.3 and I'm still seeing the warnings in the log:

Register: py.warnings
Source: custom_components/opnsense/pyopnsense/init.py:466
2024-10-26 15:49:00.913 WARNING (MainThread) [py.warnings] /usr/local/lib/python3.12/site-packages/dateutil/parser/_parser.py:1207: UnknownTimezoneWarning: tzname BST identified but not understood. Pass tzinfos argument in order to correctly return a timezone-aware datetime. In a future version, this will raise an exception.
warnings.warn("tzname {tzname} identified but not understood. "

To set the time zone to BST: In the Home Assistant interface, menu Settings / System / General / Time zone = (GMT +00:00) London

Ok, I corrected all of the other calls that used timezone to use UTC Offset instead. However, I missed the one that was actually causing the warning in the first place. This is getting the timezone abbreviation from OPNsense from when it last checked for a firmware update. I'll get that handled too.
