Reminders via Assist - Create and List Tasks with Conversational Commands
Hi everyone! 
I’m super excited to give back to the Home Assistant community – after benefiting from so many shared resources, I can finally contribute something of my own. This blueprint has been a fun project, and I hope it helps improve your Home Assistant setup!
Don’t forget to expose the automation to Assist too! It will help the new Fallback LLM handle edge cases 
NOTE: the blueprint mode is set to “single” for now because “queued” seems to cause a bug where the conversation response no longer works correctly. This isn’t ideal, but I’ll keep it like this for now until the bug is fixed.
What does this blueprint do?
This automation aims to replicate the behaviour of Google Assistant’s reminders via voice. You can set reminders and fetch a list of your pending tasks using conversational commands. It supports both relative and exact time inputs and even tries to deduce whether you meant 2 AM or 2 PM based on the context.
Inspiration
I was originally inspired by this post on local voice reminders. After trying it out, I wanted to create a slimmer version of the same idea that worked entirely within a single automation and didn’t require any additional YAML tweaking. Doing it this way also made it easy to share as a blueprint—something I was keen on!
Features:
- Add reminders with commands like:
- “Remind me to water the plants tomorrow.”
- “Set a reminder to call mom at 3 PM.”
- Fetch your task list by saying:
- “What’s on my reminder list?”
- “Show me my tasks.”
- Customizable to work with your preferred to-do list entity and voice commands.
- Tailor the voice commands to your liking
How to use:
- Import blueprint file into your Home Assistant instance.
- Reload automation (this may not be required, but when I was testing this import, some issues cropped up if I didn’t reload).

I’d love to hear how it works for you or if you have suggestions for improving it. Thanks for checking it out, and I hope it makes managing reminders a bit easier!
