Tried it myself =)
Probably not perfect but it works with the WT-09W 2-Zone Water Timer (modelCode 270)

- Add
DiivooWT09W to MODEL_CODE_MAPPING:
MODEL_CODE_MAPPING = {
code: clazz
for clazz in (
RainPointDisplayHub,
RainPointSoilMoistureSensor,
RainPointRainSensor,
RainPointAirSensor,
RainPoint2ZoneTimer,
DiivooWT11W,
DiivooWT09W, # â added
HWG0538WRF,
HomgarWeatherHub,
HomgarWeatherStation,
HomgarIndoorSensor,
HTV405FRF
) for code in clazz.MODEL_CODES
}
Changes to switch.py:
- Update the import line:
from .devices import DiivooWT11W, DiivooWT09W, RainPoint2ZoneTimer, HWG0538WRF, HTV405FRF
- Update the device setup loop â check
DiivooWT09W before DiivooWT11W:
for device_id, device in coordinator.devices.items():
if isinstance(device, DiivooWT09W): # must check before DiivooWT11W
for zone in [1, 2]:
entities.append(
HomgarZoneSwitch(coordinator, device_id, device, zone)
)
elif isinstance(device, DiivooWT11W):
for zone in [1, 2, 3]:
entities.append(
HomgarZoneSwitch(coordinator, device_id, device, zone)
)
elif isinstance(device, RainPoint2ZoneTimer):
for zone in [1, 2]:
entities.append(
HomgarZoneSwitch(coordinator, device_id, device, zone)
)
elif isinstance(device, HTV405FRF):
for zone in [1, 2, 3, 4]:
