@gndean I did more testing today, and I'm reasonably confident this is something in the integration code.

As my session was coming to an end, I've watched the Hypervolt Android app to check if the data remains misreported there as well. And it was reported correctly as soon as the session ended.

The HS entity displayed the tell-tale 1s blip at the end of the session, and then the data was misreported for the exact same length of time as the session itself.

I have a workaround in place, where I have a secondary entity that tracks the last charge session's average voltage and current, and then subtracts the power value from the reported CT clamp value if no charge session is in progress.

I'll try and check if I can debug this further at code level.

Here's an overlay of correct/incorrect data:

And the blip:

Thanks for the issue report.

The CT Power sensor is just a report of a raw field from the Hypervolt APIs. There is no processing that the integration does with it.
Since I moved from a HV 2.0 charger to a HV 3.0 charger, I no longer see this field populated at all, whereas it was with my HV 2.0 charger.
I suspect its meaning has changed internally within the HV API spec. But that's just a guess.

I appreciate your report and investigation however I am going to close this as a "won't fix" because the integration is just reporting what the HV servers supply and without any documentation, I'm not confident to make any further inferences to its precise meaning.

OK, understood.

On my HV3 charger the CT clamp data is used internally to grid load balance, and - assuming it's installed as per manual - reports the full house load, which enables the charger to manage the different boost and eco modes appropriately, especially if there's other heavy loads active during the charge session, or PV production.

Interesting that you say this data is not populated with your charger at all. Firmware differences?
Mine's at 2627.0

I've just reread previous posts - I'll report to Hypervolt.

I have a similar issue. But not sure if it's a problem with the charger firmware or integration. When my charge session ends, grid power remains at the session end power and house power jumps to the grid power value. The curious thing is... it's like Schrödinger's API, as soon as you look it returns to normal... I'm just not sure if it was opening the hypervolt app or opening home assistant that triggers the values to return. It happens at leat once a month and very frustrating.

Happy to report to Hypervolt if it's impossible that it's the integration. Just let me know.
