I’ve trouble with a self configured statistic sensor. Them same way I also configured a working one for a shorter period of observation.
Working:
- platform: statistics
entity_id: sensor.nano_pk_pellet_consumption
name: pellet-change-7d
state_characteristic: change
max_age:
hours: 168
sampling_size: 275

The source is a total increasing value with no change for negativ rates/values.

My problem is that the 30d sensort never reach ~1 age_coverage_ratio. I thought, that configuring a stat sensor is enough to keep the dates. I created that sensor last year. Do I miss something?
