huawei_solar: [Bug]: Loosing the battery configuration during the night

Describe the issue

Lately, I’ve been losing the battery controls during the night. Reloading the integration or restarting HA makes everything work.

Battery sensors, Inverter, and SmartMeter are not lost and work perfectly. It is only the controls that become unavilable.

I tried to update both the inverter, battery, and dongle to the latest version from FusionSolar. The issue still persists. I’m wondering if it happens when the battery is empty (5%) and goes into hibernation.

This is my lame mitigation so far, simply to restart HA so it works again.
