^^^^^^^^^
AttributeError: 'NoneType' object has no attribute 'isoformat'

Device is - Bhyve watering system Orbit Irrigation Product HT31BT B-Hyve XD Bluetooth Hose Faucet Timer.

Here is the key part of switch.py code -

        next_start_time = orbit_time_to_local_time(
            status.get("next_start_time")
        ).isoformat()
        if next_start_time is not None:
            next_start_programs = status.get("next_start_programs")
            self._attrs.update(
                {
                    ATTR_NEXT_START_TIME: next_start_time,
                    ATTR_NEXT_START_PROGRAMS: next_start_programs,
                }
            )

SOLUTION IS

        next_start_time_raw = status.get("next_start_time")
        if next_start_time_raw is not None:
            next_start_time = orbit_time_to_local_time(
                next_start_time_raw
            ).isoformat()
            next_start_programs = status.get("next_start_programs")
            self._attrs.update(
                {
                    ATTR_NEXT_START_TIME: next_start_time,
                    ATTR_NEXT_START_PROGRAMS: next_start_programs,
                }
            )

In this updated code:

Retrieve next_start_time from status and store it in next_start_time_raw.
Check if next_start_time_raw is not None before proceeding with the conversion to local time and the update of self._attrs.
This way, you avoid calling isoformat() on a None value and the AttributeError should no longer occur.
