Hildebrandglow - Smart Meters - SMETS2

I was interested in using this integration.
I have a SMETS2 meter.

Installed the Bright app on a tablet on Sunday. (19-2-23).
I installed the Hildebrand Glow integration after reading and following the earlier posts in this thread.

By Tuesday, there was some data in the Bright app relating to Monday.
The data during Tuesday seemed like initial values and remained static.
Now its Thursday, I can tell the app figures are correct for gas and electric up to the previous day.
So Mon to Wed are ok.

The HA integration usage figures show 0.11kWhr for electric and not available for gas.
Unit costs are not correct.

I’ve uninstalled and re-installed the integration.
It shows 2 devices and 6 entities.
When I first installed it, I’m sure it asked for an email and password, assumed to be the same as for the Bright app. It didn’t do that on the re-installation.

I’m new to this but it seems broken to me.
I’ll keep and eye on this thread.
