What

Add typed accessor properties that parse the raw wire-string fields on Zone and ThermostatState into native Python types.

Why

Every state field arrives as a raw string from the wire (indoor_temperature="74", cooling_active="2"). Today each consumer — notably a Home Assistant integration — must re-implement the parsing, including the non-obvious tri-state "0"/"1"/"2" for cooling/heating activity (only the CLI knew that mapping). That logic belongs in the library, parsed once and correctly.

How

  • New HVACActivity enum (INACTIVE/IDLE/ACTIVE) names the tri-state that cooling_active/heating_active already carried numerically. IDLE (on, setpoint satisfied) is distinct from INACTIVE (off) — maps onto HA's hvac_action.
  • Read-only properties, additive — raw strings are untouched:
    • Zone.{indoor_temperature,heat_setpoint,cool_setpoint,deadband}_f -> float | None
    • ThermostatState.emergency_heat_on -> bool | None
    • ThermostatState.{cooling,heating} -> HVACActivity | None
    • ThermostatState.relative_humidity_pct -> int | None
  • Every accessor returns None for empty/invalid input — no defensive parsing on the consumer side, no crashes on the empty-string states this device emits mid-burst.
  • emergency_heat_on uses the status encoding ("1"=on, "0"=off), matching the CLI's display labels.

Testing

uv run pytest — 161 passed (10 new, parametrized over valid/empty/invalid inputs). ruff clean. models.py at 100% coverage. README documents the accessors.

Expose parsed companions for the raw wire-string fields on Zone and
ThermostatState so consumers (e.g. Home Assistant) don't have to
re-derive parsing. Each returns None for empty/invalid values.

- Zone.{indoor_temperature,heat_setpoint,cool_setpoint,deadband}_f -> float | None
- ThermostatState.emergency_heat_on -> bool | None
- ThermostatState.{cooling,heating} -> HVACActivity | None (tri-state)
- ThermostatState.relative_humidity_pct -> int | None

New HVACActivity enum (INACTIVE/IDLE/ACTIVE) names the tri-state that
cooling_active/heating_active already carried as '0'/'1'/'2'.
