Historical Statistics helpers no update until HA Rebooting 2025.5.2

Gabr13L · May 21, 2025, 2:09pm

Hi everyone.

I’m on HA 2025.5.2 and I’ve noticed that all my historical statistics helpers (highest value, yesterday’s value, etc) have stopped updating when the day changes.
That is, starting at 0:00:01, the “today” values should be reset to “yesterday,” but they remain at 0.
If I simply restart, the historical values appear correctly.
This didn’t happen until version 2025.4.x.
Anyone else having the same problem?
Thanks

“Today” is:
start: {{ today_at(‘00:00:00’) }}
end: {{ today_at(‘23:59:59’) }}
duration: empty

“Yesterday” is:
start: empty
end: {{ today_at(‘00:00:00’) }}
duration: 0:24:0:0

Hello Gabriel,

If you believe you have found a bug and your discussions here have people agreeing with you (It’s not currently working as designed) then you should check the issues. If it is working as designed and you just don’t like it, then look at the Feature Request Category for more info.
If there is already an issue for it, add a thumbs up to help push the effort along. If there is not an issue open for it open one.
It’s good to discuss and verify that there is an issue here, but if you want the appropriate developer to look at it & maybe get it resolved, it will have to be seen as an issue…

Regression in history_stats sliding time window where end: is prior to now() caused by #143279

### The problem The history_stats optimization introduced in #143279 causes the… count values to go to zero whenever the end time of the sliding window is prior to the current time. This is because the expired values are removed from the count but the new values are not added to the count. Resulting in a zero count. When the end time of the window is now() the code works correctly. ### What version of Home Assistant Core has the issue? 2025.5.0 ### What was the last working version of Home Assistant Core? 2025.4.4 ### What type of installation are you running? Home Assistant OS ### Integration causing the issue History_stats ### Link to integration documentation on our website https://www.home-assistant.io/integrations/history_stats/ ### Diagnostics information _No response_ ### Example YAML snippet ```yaml - platform: history_stats name: Sump last hour entity_id: binary_sensor.sump_pump_running state: "on" type: count start: "{{now()-timedelta(hours=1)}}" duration: "00:59" # The above code counts a zero. # But, if I change to # duration: "01:00" # then it works correctly. ``` ### Anything in the logs that might be useful for us? ```txt ``` ### Additional information The above example is for brevity. The actual code I'm trying to get to work is for three different sliding windows. 1) one hour ago, through current time. 2) two hours ago, through one hour ago 3) three hours ago, through two hours ago. This was all working perfectly in core 2025.04 and broke in 2025.05. Now, only the window ending with current time works. The others count zero. When I reload the yaml for history stats it refreshes the counts correctly and they once again trend back to zero as the sliding window expires old data.
