I’ve recently switched from EDF to Bulb, on an Economy 7 tariff, after having a Landis E470 (SMETS2) meter fitted by EDF. Since the switch I’ve noticed that whilst my IHD shows that the night rate price kicks in at the correct time (12:30am), the E7 circuit switches on at 11:30pm (this was the time the EDF E7 night rate started).
I had assumed that it was the smart meter itself that controlled when the switch occurred and that Bulb would simply update the meter remotely to switch on the E7 circuit at the new time.
Does anyone know what actually triggers the E7 circuit switch on a smart meter? Can it typically be controlled remotely or would some other adjustment be needed?
