Be able to have a curve even if the value doesn't move

Feature requests
1

I currently have a thermostat dashboard

On it I have 3 widgets :
Room temperature, the room device with low and high temperature setpoints and the different heating modes (comfort, eco, frost protection (HG), off) and finally a chart with the temperature and the two setpoints.

The problem is that my chart only handles the temperature data because the others were given at a single time t but have not evolved.

I would like to have my two setpoints plotted and the temperature evolving at the same time

Hi @spenceur ! Interesting problem, I have no idea how to solve it though :sweat_smile:

Add to the charts an additional function allowing to define a so-called « setpoint » value (or several).
It could be either fixed with an input to enter, or via a feature variable and we’d retrieve the feature’s lastValue continuously… like that on the fly ^^

That’s a possibility! Let’s first see if it’s requested :slight_smile:

I have the same issue but since I manage my radiators with Node-RED I resend the setpoint regularly for display in the graphs.

Yeah, in this case I handle everything natively with Gladys. So if I can avoid having to add any band-aid fixes, that would be great haha

7

Yes, that’s for sure.

8

I’ll take a look afterwards at the 3 PRs in progress that I absolutely have to finish, if it doesn’t take too long. I’m also really interested ^^

Kind of like @_Will_71, but I did it in Gladys: I have a scene called « Repetition of values for 24h ‹ flat › charts »

I’m starting to look at:

Something like this?

We could also do things for per-point variable setpoints, maybe with a current setpoint line…

11

That may be interesting, but as far as I’m concerned it’s a variable instruction.

12

It’s in there!! ^^ I’m just looking for the best way to represent it ^^
I’m trying to see if I can also define a zone (like +/- 1°C, if the setpoint is 20°C there would be a zone between 19 and 21°C)

13

Some visual mockups of the edition. I’m still figuring things out… ^^ it’s a pain on large screens in 3-column mode or on small ones. A lot of info to display.

I wonder if we shouldn’t do this in two stages?
In the first stage, select the devices that will serve as threshold values.
And

15

Yes, you’re very clear ^^

@spenceur (and everyone of course ^^) :
I have progressed to try to answer this request exactly (which is quite specific to an instruction-type feature). Tell me what you (sing./pl.) think:

  • Edit - I went with the same thing as the existing one for now with an addition at the bottom of the page :

Yes, it’s very personal!

18

Another question, because it takes up space. I’d like to disable the default instructions and only show them when selected in the legend.

That means that on a refresh or a page change it will be disabled again.

@pierre-gilles,
I was tearing my hair out trying to get things to work, but it was actually broken — it was resolved in subsequent versions. I just updated to the latest version of apexcharts and it works. But of course I haven’t retested everything.

What do you recommend when updating dependencies? I tested with my current DB and it looks good. But how can I be sure it’ll be the same for everyone?

You should test all chart cases first; after that there’s not much to do, aside from testing a sufficient variety of cases!

Let me know when you’d like a review :slight_smile:
