self.set_state("sensor.my_weather_symbol", state = "Cloudy")
In the appdaemon logs, am seeing:
> 2020-09-03 08:29:17.727724 WARNING my app: my app: Entity sensor.my_weather_symbol not found in namespace default
> 2020-09-03 08:29:17.728126 INFO AppDaemon: my app: Entity sensor.my_weather_symbol created in namespace: default
Is it possible to have a diy sensor persisted between restarts? It’s no big deal, just that if the entity is added to customize.yaml, e.g:
It will not persist, but you can set the icon and other attributes in the self.set_state() call:
attributes = {}
attributes['icon'] = 'mdi:weather-partly-snowy-rainy'
attributes['another_attribute'] = "my other attribute"
self.set_state("sensor.my_weather_symbol", state = "Cloudy", attributes=attributes )
This way, the icon will always be there. Remember to include the attributes every time you call self.set_state() as the attributes are also not persistent and will be removed if you just call self.set_state("sensor.my_weather_symbol", state = "Cloudy") without the attributes.
