Sensor - Monitor values of KNX
Overview
Sensors are monitoring temperature, air humidity, pressure etc. from KNX bus.
Interface
xknxis the XKNX object.nameis the name of the object.group_address_stateis the KNX group address of the sensor device.sync_statedefines if the value should be actively read from the bus. IfFalseno GroupValueRead telegrams will be sent to its group address. Defaults toTruealways_callbackdefines if a callback shall be triggered for consecutive telegrams with same payload. Defaults toFalsevalue_typecontrols how the value should be rendered in a human readable representation. The attribute may have may have the valuespercent,temperature,illuminance,speed_msorcurrent.device_updated_cbCallback for each update.
Example
sensor = Sensor(
xknx=xknx,
name='DiningRoom.Temperature.Sensor',
always_callback=False,
group_address_state='6/2/1',
sync_state=True,
value_type='temperature'
)
xknx.devices.async_add(sensor)
# Requesting current state via KNX GroupValueRead from the bus
await sensor.sync(wait_for_result=True)
# Returns the value of in a human readable way
sensor.resolve_state()
# Returns the unit of the value as string
sensor.unit_of_measurement()
# Returns the last received telegram or None
sensor.last_telegram
