Hi,
I find myself using history graphs a lot for debugging. With a growing list of devices that’s often frustrating as I have to search a lot for the device I’m looking for.
Thus I’m suggesting some changes of the history graph. I took inspiration from the new “Integration/devices/…” page.
Here is a first mockup: (hope you don’t mind the mix of english and german, I
used ascreenshot as base)
Device type filter:
I imagined having a rough filter system at the top filtering by device type with the types used most often at displayed at all the time and others behind a dropdown. This would be enough for most of the use cased.
better time filter:
I always get confused what “for 3 days” means. Going forward or backwards from that day? A range would be clearer for the user.
search
Well, a entity search
Advanced Filter
With 2 dropdowns you could have an advanced filter, for example only those devices whose current state is on or open. Or with device type “light”. Or whose integration is Deconz. Or whatever.
So, what do you think? I hope someone likes the idea and maybe devs will take mi ideas into account. I just see that as a part in this community 
Best
