v1.31.1

The card should now work on HA Core 2025.6.0 (thanks @piitaya for the fix!). Alternatively, you can upgrade Home Assistant to 2025.6.1. Both will solve the issue of of dashboard sections disappearing when they include the card.

I've also updated the mushroom card to respect the active_icon setting, so you can now customize the icon when a timer is running.

v1.31.0

I've finally updated the card to keep up to date with the new developments in Home Assistant.

First of all, Mushroom cards now match other Mushroom cards. I've fixed the issue with large padding around the card.

Second, you can now use Home Assistant's Visibility and Layout tabs to configure the card. Visibility allows you to hide the card from the dashboard under certain conditions, and Layout allows you to configure the card's size in the Sections dashboard.

This release also introduces a small breaking change: To be consistent with the mushroom cards, the timer bar card will now render 6 units wide (half of the width of the section) when added in a Sections dashboard. To set the card back to full width, turn on Layout -> Full width card.

Other fixes:

• Rounding with format set to hm or resolution set to minutes now correctly handles rounding

Stuff Merged Since Last Release:

• Render negative times by @SLaks in #148
• Link to more instructions for Alexa by @SLaks in #166

v1.30.2

I didn't quite catch all the changes to mushroom card in the last update. This one fixes the secondary text to be consistent.

v1.30.1

This release includes a change by @SLaks that allows you to use the card without specifying any entity. It's useful if you want to create a timer that's always active or are using a template to parse and fill in the card's state. It's finally possible to use the card with integrations that squish all their timers into one entity, like Google Home, and show all their timers at once.

I've also updated the mushroom styles to be consistent with the latest version of mushroom cards. Enjoy!

v1.30.0

Timer bar card updates: they don't make them like they used to. It looks like it's been 6 months since the last one. But there's a new update launching your way now 🚀

There's some new things in this one:

• The format option lets you customize how the time is displayed. Want to show a rocket ship? format: '%m min till 🚀'
• The mushroom card supports thefill_container option. This will let it expand within grids of mushroom cards.

And fixes:

• The icons in the mushroom card will now show up. This broke in the latest Home Assistant release.
• You'll no longer see parsing errors if the timer is inactive.
• Script duration parses across all languages.
• Support for card actions should be more complete.

v1.29.1

Parsing duration now works even if the duration has extra stuff after the number. For example 30 minutes will parse as 30.

v1.29

You can now configure a start/end time/duration to grab an specific attribute from another entity by combining the { entity: ... } and { attribute: ... } configurations to create { entity: ..., attribute: ... }. It's like building blocks!

There are also three bug fixes in this release:

• States being marked as unavailable don't break the card (#92)
• Whether the Mushroom card appears in its active or inactive state is correctly determined (#94)
• Icons are back in Mushroom mode (#95)

Thanks to everyone who helped document these bugs!

v1.28.2

Put an end to the layout: hide_name bugs! This release renders the timer bar correctly when the layout option is set to hide_name.

v1.28.1

Thank you to everyone who gave feedback & ideas immediately after the last release!

This one solves a few annoyances:

• Using resolution: minutes now rounds the minutes up instead of down.
• The mushroom card in a dark mode theme will now use the correct colors.
• Mushroom timers can now specify primary_info and secondary_info like other Mushroom cards.

v1.28

🍄 Mushroom Mode 🍄

If you use Mushroom cards, this release is for you. I've added the mushroom option that makes the card appear like the other Mushroom cards. By setting mushroom.layout you can switch between horizontal and vertical layouts (great for setting up grids!).

📕 Revamped Readme 📕

The last time I organized this project's Readme was 2 years ago, and I've learned a lot about how everyone is using the card since then.

I've turned the paragraph showing how to use the card with automations into its own big section and moved it up near the top. I've also rewritten the section on working with new integrations to make it more clear how the active_state, start_time, etc. options work. Hopefully it's easier now to learn how to configure the card.

Please let me know in the issues or discussions if anything is still not clear.

🐞 Bugfixes 🐞

• The card now always refreshes whenever you change external entities/scripts it references . For example, if you have a timer bar card with one row whose duration depends on a input_number entity, updating that input_number will now update the card without needing to refresh the page.
• Fixed alignment issues when using the hide_name option.
