Feature idea: Multi-day rings

[sxdjt]

Greetings @maglerod -

I have been working on an enhancement idea for the card; multi-day rings. The feature would allow you to show multiple rings (one per day) of a single sensors data. Outer ring = today, inner rings = older days.

If this is a feature that you would want to include, I can submit a PR.

Display up to 7 days of history as concentric rings for any history or consumption layer:

• days: 1–7 — number of days to show (1 = today only, 7 = full week)
• Older days render as outer rings, today is always the innermost ring
• day_fade / day_fade_step — gradually reduce opacity on older rings
• day_labels — show day-of-week labels beside each ring
• day_label_format — label style: short (Mon), narrow (M), or full (Monday)
• day_label_position — place labels on left or right side
• Min/max scaling is shared across all day-rings for consistent comparison

layers:
  - id: temp_week
    type: history
    entity: sensor.outdoor_temperature
    days: 3
    day_fade: true
    day_fade_step: 0.12
    day_labels: true
    day_label_format: short
    day_label_position: top

Note: Multi-day mode is mutually exclusive with keep_across_midnight and day_offset.

Hi there, thank you so much for the suggestion, i really like the idea.
Have you already implemented the needed change to be able to do this?

It do support today and tomorrow information and very close to what you propose
/A

[sxdjt]

Yes, I have the change staged in my repo. I will submit it as a branch.

This version will support 7 days of history, but you would need a full screen-sized card to see the inner rings :)

Functionally, this is very similar to my waterfall history card, but I have some use cases where the clock format would be useful.

Cool, Nice work!

And the clock almost looks like a radar :). When you submitted the branch i will test it and then release it.
Will add you as a contributer, Great work and many thanks!

[sxdjt]

I am having too much fun with this :)

[maglerod]

Nice work

Hi, just wanted to check if you have made any more changes into the card and if you want to make the PR?.
I'm about to fix som bugs. just wanna check.

[sxdjt]

Hi - I have submitted #6.

This re-implements the multi-day rings that were in #4. I accidentally deleted the fork and it closed the PR. Oops.

I also updated the ha-select items; they were failing and not supported in HA 2026.*.

[maglerod]

Thanx a lot for the version and the ha-select fix as well! Great!

Happy to help, thanks for the card.
