Target state sensor with -02:00:00 offset only fired 2 minutes early

[billmichell]

Describe the bug

My “charge the battery for 2 hours before the peak rates” sensor only fired at 15:58:00, only 2 minutes before the peak rate.

I thought I saw there is a BST bug since fixed, but this only caused a 1 hour error.

Left me without enough battery to cover the 3 hour peak period.

Hello, sorry that you're encountered this issue.

The integration should be re-evaluating every minute based on callbacks from HA. If HA fails to update the underlying data or call the entity, then the state won't be evaluated and therefore won't change.

Had you done any restarts around the time it should have gone off? Do you know what the target rates were before, during and after firing?

If you're in debug mode, logs between 14:00 and 16:00 of the offending day might help give a clue.
