I have a wind speed that I am getting from ESPhome where I have applied a filter with a sliding_window_moving_average. I want to do the same thing with a diferent value I am getting from mqtt. But if I try to add a filter to the mqtt value, HA complains that my configuration is invalid.
This is what I have in my configuration.yaml currently:
- platform: mqtt
state_topic: "doorbell/Light_level"
unit_of_measurement: 'lm'
name: "Light level (hall)"
How can I create a moving average of this value? I get a new value once a minute.
