Feature Request: kW when charging about home-assistant-hypervolt-charger HOT 10 CLOSED

How are you getting on with this?
I've released it as part of version 1.2.1, as I needed to push out a fix, so I've rolled it into that.

Yes I suspect converting the amps might be the way to go.

Was going to probably to create a template sensor to do that. Wanted to check in the meantime if the API gave access already; or whether @gndean would consider doing the amps conversion within the integration to allow easier deployments for those that don't play around in YAML much,

Yeah, there's nothing I'm aware of within the API that would give realtime power.

As @exalyte says, CT Power potentially measures more than just the car charging, I guess depending on where the external CT clamp is situated. For me, it certainly measures more than just the car charging.

I had considered exposing a sensor that just multiplied the charger current x voltage. But it looks like the Hypervolt 3.0 doesn't ever set the voltage within the API: #18 So maybe the best that could be done with be to used some fixed voltage. But then, that feels like something that could be done with HA itself.

Thanks @gndean - considering HV v3 doesn't set the voltage, I can see how it would be hard to do within the integration.

I think I'll just create a template sensor using the amp and voltage readings in my calculations (I'm on a HV v2).

Thanks for looking into this 👍

Reopening this with a potential solution.

Please see and try out:

1.2.0 Beta

Added new sensor:

Hypervolt Session Power

Estimates the current charging power.

This measures increases within the Hypervolt Session Energy sensor to estimate the instantaneous power. Since the increments with Hypervolt Session Energy are somewhat lumpy, an up-to-a 5 minute window is used to calculate the current power. So if the power changes mid-charge, there will be some lag before it's reflected in this sensor. Similarly, the values within the first minute or so can be noisy.
But since the sensor uses the same figures as the energy calculation from the charger, they should lead to consistent figures and sum up to total energy consumed.

Thanks @gndean, I’ll test this out this weekend 👍

Sorry @gndean! Life issues took over, and I wasn't able to fully look into this.

However, yes it's looking good and have seen you added it to 1.2.1.

Thanks for picking this up!

Closing now as this has been released

from home-assistant-hypervolt-charger.

The integration now exposes a "EV Power" entity which should be used instead of Session Power. The HV APIs provide this power measurement so it's likely to be more accurate and quicker to respond than the derived Session Power value.
