Heatcurve

Is this a good idea?

X-y Chart is tricky- I can share the code.

ahhh.. this is a bit criptic. Can you explain what I am looking at?

I see X-axis the temperature. Outside temperature?
What is Y-axix?

[WP-Rue]

On y-axis is the poduced heat energy, on x it is the mean day temperature..

Okey, yes. It is a nice graph! Certainly.

I am wondering if this is useful for all users. Are there more people that would like to see this?

Alternatively, what I can do is put the code on Github as a separate 'plugin'.
If people want to see this, they can import this code into the basic flow.

Is this a solution you see happening? or is there a reason I am missing why everyone should have this 😄

It is a maybe nice to have, if you like to know the energy consumption of your home for different temperatures. And because (from my point of view) it must be a straight line - no curve - so you can extrapolate the need for heating energy for very cold weather, e.g.
It is tricky in nodered to show a x-y-chart (but with dashboard version 2 it could be much easier) so this was an extra motivation, to try this.
The code is not perfect- at the moment a global variable array gets bigger with every day...but I have my line now- and can see, that my 7kW heatpump is to small for colder winters...
So maybe keep in mind this feature, if someone asks.
