The history dashboard is updated live when new data comes in, but it does not show the last value in text form.
The current value shown along with the graph when clicking on an entity on a dashboard, but this graph doesn’t auto-update. Only the text representation of the sensor value is live-updated, with the result that the graph and the value doesn’t match.
This is especially visible if you have a steep change in sensor values, like a humidity sensor, when you are letting in some fresh air:
I don’t know what the HA term for the image I posted.
Either way, I find it annoying that I can’t have a detailed view of both the recent history of an entity and the text representation of the current value on the same page, without having to create a dashboard with that specific info for every entity in HA.
Elaborating a bit on what it is I don’t understand:
I think you are trying to say that the data shown may come from 2 different sources and may have different resolution depending on whether or not the entity is LTS enabled or not?
That might be the case, but there’s no obvious difference between the data shown in those 2 cases for an end user. I think what confuses me here is the use of the term Long Term Statistics, when the shown data (24h) is always within the default recorder retention period (10d). If the data that is shown in that view is within in the recorder database TTL anyway, why is there a need to distinguish between sensors that have LTS and sensors that doesn’t? Or is there more info in LTS that will enhance the graph data even if the range shown is within the recorder ttl for non-LTS values?
And how am I supposed to know that I am looking at 5 minute average values as indicated by @Ildar_Gabdullin? The only hint that the graph is showing an average value is the very faint min-max indications on the graph where it has had big fluctuations within a short period of time. At the very least, it would be nice with a better description of what I am looking at, so I know what to expect.
isn’t supposed to always show the last 24 hours? If so, what exactly is it supposed to show? I.e. what is the expected visual difference between an LTS-enabled entity and a non-LTS entity?
This is turning more and more into a “WTH is this graph, and what is the intention with it?”
OK. So for non-LTS entities it is the raw data that is graphed, but for LTS it’s 5 minute averages. And it turns out that non-LTS entities ARE live-updated.
So let me modify my original WTH question:
WTH is this view showing two substantially different things depending on whether o not the the entity is LTS-enabled? This is especially confusing since
there is no indication anywhere in that view that indicates this difference (except for the graphs being different). E.g the heading is “History” in both cases.
One mode provides live-updates while the other one doesn’t update at all.
This is underscored by the amount of posts it took in this topic to explain what was supposed to be shown in each of those 2 cases. And we haven’t even gotten to the point where someone was able to explain the reasoning behind this difference.
It might be supposed to do that, but at least for me, it doesn’t. I checked before I originally wrote that it doesn’t, because I wanted to be sure. I have the tab open where I did the original screenshot in, and it’s stuck at the time when I did the screenshot.
Good for you.
I highly doubt that the issue is that the browser went to sleep, since the raw sensor value above the graph keeps updating as new sensor values comes in.
And I just double-checked now, by opening up the view on another LTS-enabled entity, and sat here staring at it for a complete 6 minutes to be sure it wasn’t just at a matter of the graph updating outside of an “even” 5 minute boundary, but still no update to the statistics graph. The rightmost visible timestamp stays the same.
When you state it works for you, when exactly did you verify that? You’ve posted ~1 minute after my posts, so you can’t have spend a lot of time on that verification.
I thought this month of WTH was about lowering the bar for reporting issues and raising feature requests. The bar might have been lowered, but if this is the experience when the bar is lowered, I’d rather not participate in any kind of issue-reporting under the normal procedure.
Where in any of the comments has the WTH been closed? Are we still talking? Is there still a conversation? Are people still able to vote?
The answer is yes. So I have no idea why you’re getting the impression that the WTH is invalid.
PS: We are 3 days now and you still haven’t voted for your own WTH.
Lastly, I have just been providing information about the current functionality and from the beginning and your posts/replies seem to show that you are offended by these responses. I have no idea why. Someone replying to you with how something currently works does not invalidate the WTH, nor should it get a combative response. This is a discussion, WTHs are deemed closed when the WTH has been satisfied. Only at that point will the thread be closed.
If I can chime in, to make things even more confusing: for me even a quantity that is recorded in LTS has updates every 10s in both the graph and the data tip.
Note that I checked this a) in the mobile app b) in the ‘history’ dashboard , not a dashboard history graph c) in the 2025.1 beta release, which has some added features for history graphs.
OP asked here about a graph in more-info which is a statistics-graph (5minute).
What you mean is a History page which does contain a LIVE HISTORY which could be augmented by LTS (hourly).
