Calendar functionality not working since BST change

[andrewmooreio]

Version of the custom_component

1.7.2

Describe the bug

Since the clocks went forward last night (maybe a coincidence but it was working yesterday), the calendar functionality of the integration is no longer working. There are no calendar entries for the daily charge and the following error shows up on the calendar page:

First thing I did was update to 1.7.2 because there was a fix relating to timezones, but that doesn't seem to have resolved the issue.

I'm seeing a recurring error in the logs, which I've pasted below.

Apologies - I half expected something to break even though I'd been super careful with datetimes. All sorted in #236

@nathanmarlor I've updated to 1.7.4 and the issue still persists:

Is there any more info I can provide to help diagnose the root cause?

[nathanmarlor]

Hmmpphhh.

Can you try removing the integration and re -adding please? At a guess the cached schedule still has some timezone weirdness going on.

[andrewmooreio]

No problem. I'll probably end up doing it tomorrow, purely because I'm at 8 API hits on Solcast today. Re-installing will take me to the limit.

I'll let you know! Thanks.

[nathanmarlor]

No problem. Back to fully functioning on my HA after reloading so I'm sure it'll sort yours too. Hopefully that's the last of the timezone gremlins 😂🤦

[andrewmooreio]

All good after a clean reinstallation 👍
