Some feedback: - about 4 minutes to perform the 3 aggregations (3 months, about a dozen devices) 🚀 - the widget on the dashboard is very easy to understand and use 👏, it is also very responsive, regardless of the interval chosen - same comment from @VonOx about the title. If it’s a field with autofill, it should be placed after the device selection. Otherwise, it’s frustrating to enter something and have it automatically replaced - when there are no values, « interval » is written as « intervalle » in French 😉 - same comment from @VonOx about the time display for « Last 24h » (there’s a missing S, by the way) Great job anyway, it’s a great feature ---

In my opinion, it’s the SSD disk part of the MacBook Pro that is fast, because it’s almost all disk in the end (reading/sampling but it’s quite fast/writing). So if you have a good SSD on your Pi, it should also be good in terms of performance in my opinion 🙂 > [@cicoub13](#): > > Is there a Docker image available? I’ll build an image 🙂 ---

The issue is that there was a double bug in the code and in the tests that made this -1 value never work… Here’s what happened: - « -1 » behaved as if you wanted to keep only the states older than « 1 day in the future » (NOW - (-1) = TOMORROW) 😱 There was no if(-1) to block the state purge, I think I must have forgotten when coding it. As we weren’t using sensor values from the past yet, it wasn’t noticed. What surprises me is that I think @Terdious has an unlimited history on his instance. Do you confirm @Terdious? I think you must have deliberately removed this variable from the DB, right? - In the tests, a fairly silly mistake, I used fake.resolves() to mock the call to variable.getValue(), except that I misused fake.resolves() and so when I had to do my tests at the time, the -1 behaved as expected, because in short I ended up with a returned function instead of -1, and thus it prevented the purge, in short a very silly thing (it was at the very beginning of v4 about a year and a half ago I think :D) I fixed the bug and added more robust tests to ensure it doesn’t break again. In the UI, there is now the possibility to modify the value in the settings: ![Screenshot 2021-09-27 at 10.31.24](https://gladys-assistant-community.b-cdn.net/uploads/default/original/2X/c/c36775706dc96ed7b7a63e33d1379a3e82492e16.png) ---

@cicoub13 @VonOx To resolve the issue with displaying the date on the « last hour » or « last 24h » view, I changed the default view.

This type of sensor can also be very useful for boolean sensors (presence sensors, opening sensors, etc.). By the way, in the case of a presence sensor, how are the data displayed? « Presence detected between 2 PM and 3 PM » with a display of « 1 » on the curve and then « 0 » afterwards? ---

Indeed! > [@lmilcent](#): > > By the way, in the case of a presence sensor, how are the data displayed? « Presence detected between 2 pm and 3 pm » with a display of « 1 » on the curve and then « 0 » afterwards? It depends on your presence sensor, whether it sends « 0 » values or not. If it only sends « 1 » values, it won’t move (even if you see the points, it won’t be very visual). For presence sensors, I think a « heat map » display with presence/absence times would be better, like this: (so with only 2 colors) ![Screenshot 2021-09-27 at 15.33.40](https://gladys-assistant-community.b-cdn.net/uploads/default/original/2X/8/8266a60696bbb63e79cb27ba69094fa0dce1ce71.png) This is not included in this development, as it is quite different and specific to presence. We will need to discuss many points before starting this development as I think it is not as simple 🙂 > [@lmilcent](#): > > Does it already exist or is it being created? I would like to test it 🙃 Not yet, I was planning to build it at the end of the day after all my developments of the day, I will post a message here when the build is ready 🙂 In the meantime, everything is already in the PR on GitHub, but you need a development environment. ---

What are the current limitations? I thought I could display all types of values for the moment (even if the chart is not made for it), which is not the case (e.g., presence sensor, opening sensor). Edit: I just created two tests, which do not seem to work. ![image](https://gladys-assistant-community.b-cdn.net/uploads/default/original/2X/6/69de7cc9f39918e971e77113ded37d27a8a78db3.png) ![image](https://gladys-assistant-community.b-cdn.net/uploads/default/original/2X/e/ece28ba10fda69f241eefb57c21209b345cebe3c.png) BUT I realized that it’s because of `Display axes? = No`. - `No` = Does not work - `Yes` = Works I suggest preselecting « Yes » by default for displaying axes. ![image](https://gladys-assistant-community.b-cdn.net/uploads/default/original/2X/e/e24361e3e3d057ba40804af17ff532be6e2ad1c0.png) [Previous page](https://community.gladysassistant.com/t/affichage-des-courbes-de-capteurs-sur-le-dashboard/6535.md?page=1) [Next page](https://community.gladysassistant.com/t/affichage-des-courbes-de-capteurs-sur-le-dashboard/6535.md?page=3)
