@bazzabear can you explain the reset procedure for the ihd please.
I have no reset procedure for the IHD. It was the gas meter itself which I had to reset as it wasn't sending readings to either the IHD or to the supplier. I can find that and post it if it would be useful.
My IHD is still using the wrong tariff for gas, and therefore giving a wrong £ reading (about 1/3 of reality). I've just got off a webchat where I finally spoke to an actual person. Not that it was a lot more helpful.
They told me the IHD was faulty so they would send a new one.
I said I couldn't see how it was a fault. It is correctly reflecting the kWh use - just the tariff is set wrong so they need to send updated tariff information.
They said that actually it's a network fault, and my meter isn't sending readings at all and that's why the IHD is showing incorrect information.
I told them that was the case, but I reset the meter on the 22nd, since when I can see that the online read out and the IHD readout both match the usage showing on the meter itself, so it definitely is sending readings.
So they told me that the IHD is faulty again and they should send a new one.
I said again - I can't see how that can be the cause. It's just got the wrong tariff set. But if you think a new IHD will fix it, feel free to send one.
They said it surely will.
So I have to wait for the new IHD now. I guess there's a good chance it will fix the issue - assuming the new IHD already has the correct tariff information set. And I suppose that it is possible there is a fault which is stopping them sending updated tariff information to the current IHD. But it sounds a lot more like the person didn't have the faintest idea.
