WLED Countdown Timer

Blueprints Exchange
1

This is a blueprint to do a countdown timer on WLED powered strips. It:

  • makes a new segment (of whatever length you choose)
  • displays a coloured bar on it that gradually grows over the given duration
  • plays another animation for a while to signal the end of the time.

Note: it does require that the WLED devices have MQTT switched on, and the dev_name input needs the MQTT IDs (where the MQTT topic is mqtt//api)

Open your Home Assistant instance and show the blueprint import dialog with a specific blueprint pre-filled.

Cool! I just did similar about 2 weeks ago but used Node Red. I only setup a 5 minute version for now but will add 10, 15, and 20 minute versions in near future. They help giving kids time limits or warning until bedtime.

Hello dmr,

Thanks for contributing to the community with a new Blueprint.

I have a suggestion for you. Many people who are not familiar with directory structures will have problems installing this without the Home Assistant MY tools.

Adding a MY link for this Blueprint to your top post would help them a lot.

Here is the link to make that.

Done! It’s up on github now, with a button link.
