How does one count the Ontime of the state of a switch from on to off time, not from start of day?
e.g.
Start at zero
Count up in minutes
Stop the count when the state changes to off
Then when the state turns back on Start at zero again?
I guess I want the start stop and duration based on the entities state, not a time or day.
History Stats
This looks like the closest example but uses start at the beginning of the day.
sensor:
- platform: history_stats
name: Relay Ontime
entity_id: switch.off_wall_sw_relay_1
state: "on"
type: time
start: "{{ now().replace(hour=0, minute=0, second=0) }}"
end: "{{ now() }}"
