- Turn off the printer after a delay
Fault action examples:
- Turn on a red warning light
- Flash lights to get attention
- Pause other printers in your farm
- Send urgent alerts to multiple services
Use these in your TTS messages:
| Variable | Description | Example |
|---|---|---|
{{ printer_name }} |
Printer name | "X1 Carbon" |
{{ task_name }} |
Print job name | "benchy.3mf" |
{{ print_weight }} |
Weight in grams | "15" |
{{ progress }} |
Progress percentage | "100" |
{{ status }} |
Current status | "finish" |
- Set progress threshold to 98-99% to capture before the bed drops
- Add a snapshot light for consistent lighting
- Use a 1-2 second delay to let the camera adjust
- Set time windows to only get critical alerts during certain hours
- Set start and end to the same time to completely disable critical alerts
- Use "Never Critical" option to always get normal notifications
Perfect for overnight prints:
- TTS quiet hours: 22:00 → 07:00
- You'll still get mobile notifications, just no voice announcements
Create a separate automation from this blueprint for each printer. Use different:
- Notification tags (automatic based on printer name)
- Snapshot lights
- TTS messages
This happens when trying to reimport from a URL. Instead:
- Download the YAML file manually
- Place it in
/config/blueprints/automation/custom/ - Restart Home Assistant
- Ensure
/config/www/snapshots/directory exists - Check Home Assistant has write permissions
- Verify your camera entity is working
- Verify your TTS service name is correct
- Test your media player with Developer Tools → Services
- Check you're not in quiet hours
- Verify
notify.mobile_app_*service exists - Check the notifications enabled boolean is ON
- Review cooldown settings
