Feature Request: Binary / Habit-Tracker Mode (On/Off only)

[sascha303]

Hi! I love the card!
It would be awesome if there was jsut a simple mode for tracking. I want to track my gym progress (only the days, when I go, not any session lengths).
Would be cool if there was a binary mode for stuff like this, if the State was "ON" at least once during the day

Hey @sascha303, thanks for the suggestion!

I've implemented this in PR #10. You can now use binary mode for simple on/off habit tracking:

  type: custom:calendar-heatmap-card
  entity: input_boolean.gym_tracker
  title: Gym Activity
  binary_mode: true
  binary_on_state: "on"
  binary_color: "#4CAF50"

This will show active days as solid colored cells, and the detail panel displays "X / Y days (Z% active)" instead of duration.

Let me know if this works for your use case!

Thanks for implementing this! It's exactly what I was looking for (for medication tracking).

I'm only getting 10 days of history, despite the binary sensor I'm using having more than 10 days of history available. Do you know why that is?

I also have 2 of the last 10 days that should be green, but they're not.

Hey @jwildman16, thanks for the feedback! Let me try to help debug this.

On the 10 days of history, Home Assistant's recorder integration only keeps 10 days of history by default. Could you check your configuration.yaml for a recorder: section? If it's not there or doesn't have purge_keep_days set, that's likely it. You can increase it like this:

recorder:
  purge_keep_days: 30

Note that this only affects data going forward, it won't backfill history that's already been purged. Also note your disk space is going to fill up more based on this!

On the 2 missing days, I'd love to dig into this but need a bit more info:

1. Could you share your card configuration? (the full YAML)
2. What entity are you using? (e.g. binary_sensor.x or input_boolean.x)
3. If you open your browser dev console (F12 → Console tab) and reload the dashboard, you should see lines like:

   Calendar Heatmap: Processed X entries, skipped Y entries
   

   Could you share those numbers?
4. Could you also check the HA History panel (Settings → History) for that same entity and confirm it shows those 2 days as "on"?

That should help us figure out where things are going wrong!

Cheers
Micky
