I am actually optimizing my heating and it would be really helpful to have a temperature average overlay for the energy dashboard to have it at a glance.
Furthermore, it should be possible to add not only one temperature, since most heating systems provide a calculated ambient temperature considering the building time constant depending on isolation.
I would also find it very useful to have a temperature overlay. Something like in the sketch I whipped up. It could even be a toggle to show/hide (as I find it mostly useful during the cold seasons).
Also keen on this feature as we’re now in winter and its interesting seeing the changes in our energy usage, but the key missing element is the outside temperature/weather component.
