YOU CHOOSE THE CONTROL MODE
Automatic protection
ON: battery rules can turn loads off and block ON commands. OFF: control the loads manually despite low battery voltage or percentage. Sensor-fault, temperature, current and overvoltage checks stay active in both modes.
Waiting for the ESP32's confirmed mode.
MANUAL BATTERY OVERRIDE: low-voltage and below-50% fan protection are OFF. Continued discharge can damage the battery. Missing or faulty sensors still block ON. Turn Automatic protection ON to restore battery rules; no load restarts automatically.

Supply voltage is measured before each relay and can remain present while its load is OFF. States are device-reported commands, not independently verified contacts.
Try the fan protection
Synthetic battery estimate only. Below 50% locks the fan; 55% unlocks it without restarting it.
