Better history graph for distinct states | Home Assistant | Page 1

I'm using the History graph card to show the states of my heat pump (off, heating, hot water production).
Unfortunately, everytime i look at the graph i need to relearn it, because the colors seem to be somewhat random, and i cant seem to find anything in the documentation about how to specify them explicitly.

In the provided screenshot, yellow is "off", blue is "heating", which is already counterintuitive.
Anyone got any tips on how to give it more consistent visual language and maybe make it look a bit better?

i'm using the mini-graph-card a lot, and i've also looked at apex chart. But they all seem very focused on line charts, not so much showing distinct states.

there have been a lot of dashboard updates/improvements lately. Is your system up-to-date?

#

Yes(-ish), i'm on 2025.9.1

i just did another docker pull/restart, i'm on Core 2025.9.1, Frontend 20250903.3 now. i'll keep on it

#

usually i update on the day or the day after the monthly release

#

try out the new cards, maybe you find a nice one

wise strategy, personally i prefer to go beta, that way i notice errors and breaking changes causing trouble and can follow discord chats in beta channel. Do have good stable backups though

While i do love tinkering with my HA instance, i'm running quite a sizable setup throughout my house. And with networking, cameras, HA, a heatpump, a PV system and everythign being pulled together in HA automations.... yeah running beta would be a bit of a risk, i'd rather keep things stable 😄

#

But it doesnt look like theres anything around regarding my initial question in the changelogs for the past or upcoming releases. I'll keep an eye on it

Your heat pump is not a climate entity?
If it's just a sensor, generally there's not a way to customize the history colors for arbitrary strings.

#

Generally climate entities are shown as a line chart with heating/cooling overlays.

This is a central house heating heatpump. so it produced warm water into a buffer, which gets circulated around the house through the radiators. and it also produced domestic hot water, in a separate cycle. thats why ONE of the entities it provides is "what is it currently doing: nothing, heat the house, heat the water"

#

there is also a climate entity for it, which controls the target temperature for the guide room for it. its basically meaningless tbh

This reminded me I had an old PR to make enum colors stable in the timeline graph, which this might improve for you, if your sensor is correctly an enum, which I think it should be?

#

You won't be able to pick the color but at least it will stop changing 😂

yeah, that would indeed already help quite a bit 😄
