History Stats Does Not Update Until HA Restarted

Configuration
1

Hi there,

I have a “history stats” sensor that has been working for months, that all of a sudden stopped working. I’m curious if anyone has had this happen to them recently. I am trying to figure out if it is user error (my issue) or a bug in the current HA core.

The sensor tracks how long my baby has napped today:

  - platform: history_stats
    name: Ethan nap duration today
    entity_id: input_boolean.napping
    state: "on"
    type: time
    start: "{{ now().replace(hour=1, minute=0, second=0, microsecond=0) }}"
    end: "{{ now() }}"

The napping boolean was on for about 3 hours today:

But the value is 0:

Note: I have also seen the value not getting updated often, and then when we turn off napping all of a sudden it jumps.

(Note, at the time that the screenshots were taken above, it is 2:30 PM local time.)

Thanks!
Matt

Ah wow, restarting Home Assistant results In the proper value being shown. So it sounds like it is tracking it properly, it just doesn’t update.

Same here: the value is 0 until I restart HA.
