@joss yes IHD aka smart meter. So yours is set to half hour readings allowing you to view costs for half hour or daily via your online account/app? I only get a bill every 6 months and can’t see costs daily, by switching supplier my IHD would go dumb as its a smets 1, which I was happy for it to do tbh. The downfall I wouldn’t be able to get daily/monthly costs and would still have to rely on my spread sheets.
Err lets be clear. A smart meter is fitted near your in coming power supply and fuse box. An IHD is not a smart meter per say. It just takes a wireless feed from your smart meter and displays your usage via IHD.
