Hi, I had my smart meters installed yesterday lunchtime, this morning my IHD tells me I used a combined gas and electric totalling over £25!! there is no way this is correct. My daughter had a shower this evening for 5 minutes and the electric cost went up on the IHD by £5.....anyone else having these unusual readings? its worrying me as my bill is going to be massive!

Nothing useful so far but I see others are also experiencing incorrect tariffs in their In-House Displays.
My usage recorded by the IHD appears correct - just the money amount is out by a factor of 10.
There seems to be a massive silly bug in IHD units being supplied with 2nd gen SMETS2 smart meter installs. Even with the right tariff and kwh readings it fails at doing the basic maths to calculate the the cost.
For now, our one is just turned off until there's some kind of official announcement about how they're going to fix this daft bug.
Update 18/11/2019: OVO are rolling out firmware updates region by region which is fixing the issue causing IHDs to show incorrect figure.
