sensor.evnex_home_charger_grid_power Only updates when plugged in

Hi guys,

Thanks for your work on this integration. Thanks for introducing

sensor.evnex_home_charger_grid_power

In the latest update.

It only appears to update this sensor when

binary_sensor.evnex_home_charger_plugged_in
State: on

Is this intentional?

When I unplug the charger the grid power sensor value remains stuck at the last value just prior to being unplugged.

Happy to do testing if required.

Start by reproducing the issue with sensor.evnex_home_charger_grid_power while binary_sensor.evnex_home_charger_plugged_in changes from on to off. Trace the integration's sensor polling and update path, then verify that the grid-power value reflects the unplugged state rather than remaining at its previous reading.
