Live Load data not available

[nbmkiwi]

Is it possible to get the live load data (that shows in the app, if you have the CT connected), so you can see the amount of electricity being drawn from the grid (or potentially exported to the grid). As I’d like to use that data for the energy dashboard in Home Assistant.

Can you provide an example (redacted) api request and the redacted output from the browser network tools?

I don't have any CT connected so not seeing it!

I'll make a best guess that should either work or not do any harm as I'm about to cut a new release

I have a CT clamp installed and connected (features.PowerSensor.unlocked: true), so I can confirm the supplyActivePower guess in the current release is right, with one caveat and a related bug.

supplyActivePower is correct, and it reports net grid draw, not just charger draw:

05:35 local, car charging, no solar: supplyActivePower: 12502 (W), power: 6654 (W), importing.
16:10 local, idle, daytime: supplyActivePower: -574.85 (W), exporting about 0.57 kW.

So the sign convention is positive = importing, negative = exporting.

Caveat: the connector.meter.supplyActivePower field returned by get_charge_point_detail_v3 (what the ha-evnex connector_supply_power sensor reads) only updates during an active charging session. While idle, meter.updatedDate stays frozen at the last session's timestamp, so it's not a live household grid feed.

A live reading is available via a different call: get_charge_point_energy_meter_reading (POST /charge-points/{id}/commands/get-energy-meter-reading). This returns a fresh, current-timestamped supplyActivePower even while idle, confirmed above. The catch is it has no explicit timeout and falls back to httpx's ~5s default, which is too short for a live round-trip to the charger. It raised ReadTimeout (treated as "offline") until I passed timeout=30, after which it returned in 15 to 20s from a charger that was networkStatus: ONLINE / ocppStatus: AVAILABLE the whole time. Suggest raising the default timeout for this method, same as get_charge_point_override already does.

Happy to share full redacted request/response JSON if that helps.
