Hello, I did find a thread that discussed the same problem I am having. My history stats sensors are not appearing in the entities. I have only on instance of sensor: in my config.yaml. Here is the code I have for the history stat sensor. Any help in solving this would be appreciated.
- platform: history_stats
name: Diesel burner on time
entity_id: sensor.diesel_burner_status
state: '01'
type: time
start: '{{ now().replace(hour=24).replace(minute=0).replace(second=0) }}'
end: '{{ now() }}'
