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.
