options list None In case this sensor provides a textual state, this property can be used to provide a list of possible states. Requires the enum device class to be set. Cannot be combined with state_class or native_unit_of_measurement.
I have created an integration and would like to return “On” “Standby” “Cooling” “Emergency”
but I cannot understand how to define the Option list and to return it.
Right now I’m returning an integer value 0,1,2,4
"""Get the latest value for this sensor."""
"""all the code to get the value[] and then """
self._state = value[5]-48
To return a list of possible states for a sensor in Home Assistant, you can use the options attribute in the sensor’s configuration. The options attribute should be a list of strings, where each string is a possible state for the sensor. For example, to return the states “On”, “Standby”, “Cooling”, and “Emergency” for a sensor, you could use the following configuration:
sensor:
- platform: my_custom_platform
name: My Sensor
options:
- On
- Standby
- Cooling
- Emergency
In your sensor’s code, you would then need to return the appropriate state string from the options list based on the sensor’s current value. For example, if your sensor’s current value is 2, you would return the string “Cooling” from the options list. This can be done using the index() method, which returns the index of a given value in a list.
Here is an example of how this could be implemented in your sensor’s code:
def update(self):
"""Get the latest value for this sensor."""
value = get_sensor_value() # Replace this with your code to get the sensor's value
# Get the corresponding state string from the options list
state_index = value[5] - 48
state = self.options[state_index]
self._state = state
In this example, the sensor’s current value is used to determine the corresponding state string from the options list. The state string is then assigned to the sensor’s _state attribute, which will be displayed in Home Assistant.
