Apparently I’ve used an entire weeks budget in 2 days!
is there some kind of settling in period or is there something amiss?

Please note my comments there, that these erroneous readings by the IHD are not within OVO's field of responsibility. The IHDs and their firmware are approved by DCC and Ofgem. They are from a 3rd party supplier and used by many Energy Suppliers.
There certainly is a settling in period as you refer to it. It takes about 5-6 weeks of testing and commissioning before your real tariff data finally gets uploaded to your SMETS2 meters by OVO. There's more discussion about that on the other Topic I've just referred you to.
