Hi HA folks,
I know from other programs that it is possible to read data in a diagram with precise time using a cursor and in relation to other values and switching states in a very practical way.
The current situation in Home Assistant is that if, for example, I read a temperature at 11:00 with the mouse cursor, I only see this value displayed in the pop-up window, but not other related values at exactly the same time.
This is helpful, for example, if I want to read one or more temperatures at an exact time switch point…
Attached an example screenshot from software that I use for my heating system.
There is a cursor (vertical dashed line) that can be move and on the right a list of the corresponding switching states and values.
Everything related to each other at a specific timestamp.
I think it would be great if something like this, or something similar, could be integrated into the Home Assistant History.
Hope you vote for this suggestion 
Many thanks
PS: There is another request for an improvement to the History Graph, which I see as a good addition → Improved device graphs with zoom in time scale and more
