Time did not adjust correctly at start of BST
Posted: Sat Apr 04, 2026 3:22 pm
I have a time poriod set up to match Octopus Go low tarrif 00:30 05:30 to charge the battery to a %. The purpose is to ensure enough energy for the house until the sun comes up and stop the charge going to the car if it is charging.
At the start of BST, this did not work correctly and stayed avtive for an extra hour.
As the clock change is defined to happen at 01:00 the low tarrif is only for 4 hours. The car charger cut off correctly at 05:30 BST ( 04:30 GMT) but the Fox inverter changed modes an hour later 06:30 BST (05:30 GMT)
The result is tbat the house stayed on grid for an hour of peak rate power.
The inverter time is correctly on BST now.
Has anyone else seen this problem?
