sensor.epcube_battery_power frozen state during standby / incorrect reporting

[vincenzocrupi]

The integration reports incorrect or "frozen" values for the battery power sensor when the system should be in a standby or idle state. Instead of showing 0W (or a minimal idle consumption), the sensor remains stuck on a specific last-read value for an extended period.
Technical Details:
• Affected Sensor: sensor.epcube_battery_power (and potentially related power entities).
• Observed Behavior: The sensor does not update its state to 0 when the battery is not charging or discharging. It retains a value (probably the last reported value ) until the battery will reports new real values, even when there is no actual power flow.

Can you please investigate?

This is an example of the bad value reported this morning at 6AM.
In the situation where I have a total consumption of 400W and 400W withdrawned from the grid, the battery actually is in standy-by also according to original EP Cube App.
