fix(turbro_poolheatpump): handle devices without preset DP (#6093)
This fixes target temperature scaling and HVAC action reporting for
compatible AquaViva Model 12 ON/OFF heat pumps that do not report DP 2
locally.
The device diagnostics show that DP 2 is absent, DP 5 contains the
operating mode, DP 6 is `c`, and DP 101 contains `290`. The internal
`set_heating_temp` value was correctly decoded as `29.0`, but the main
climate target was exposed as `290 °C` because its redirect depended on
DP 2.
This change uses the existing DP 5 mappings as a fallback when DP 2 is
unavailable. Devices that report DP 2, including the existing TURBRO
variants, continue to use the original mappings. The same fallback lets
a presetless device report `cooling` from its work mode instead of
falling back to `heating`.
The AquaViva Model 12 ON/OFF (`AVM-ON12RW`) is also listed as a
confirmed product for the shared product ID. This allows users to select
the correct manufacturer and model during setup while keeping the
existing TURBRO entry.
Tested on a physical AquaViva Model 12 ON/OFF:
- Target temperatures are displayed correctly as 28, 29, and 30 °C.
- The target changes in 1 °C steps.
- Changes made in Home Assistant are reflected in Smart Life.
- The config flow exposes both TURBRO and AquaViva product labels for
the shared product ID.
- Simulated Heat, Cool, and Auto DP states read and write the correctly
scaled values.
- Existing TURBRO DP paths remain unchanged in regression checks.
Validation:
- `ruff check .`
- `ruff check --select I .`
- `ruff format --check .`
- `yamllint custom_components/tuya_local/devices`
- `pytest tests/test_device_config.py` — 32 passed
