Bambu AMS Monitoring

A custom Home Assistant integration to monitor and control your Bambu Lab AMS filament status.
Connects to the bambulab-ams-spoolman-filamentstatus backend with a simple toggle switch per printer.

Note: This integration depends on a working bambulab-ams-spoolman-filamentstatus environment.

Features

• Toggle monitoring per printer directly from Home Assistant
• Auto-detects all available printers from your backend
• Availability tracking — entity shows as unavailable if the backend is unreachable
• Multi-printer support — add multiple printers in one integration instance
• Fully translatable — English and German included

Setup

1. Go to Settings → Devices & Services
2. Click Add Integration and search for Bambu AMS Monitoring
3. Enter the base URL of your backend, for example:

   http://192.168.1.100:4000
   https://ams-server.example.com
   https://myserver.com/ams

Configuration

After setup, you can edit the printer selection at any time:

1. Go to Settings → Devices & Services
2. Find Bambu AMS Monitoring and click Configure
3. Adjust your printer selection and save

Entities

For each configured printer, the integration creates a switch entity:

Entity	Description
switch.ams_monitoring_<printer_name>	Enables / disables filament monitoring for this printer

The switch reflects the actual monitoring state from the backend and updates automatically.

Troubleshooting

Config flow fails to load Make sure the backend is reachable at the URL you entered and responds at /api/printers.

Entity shows as unavailable The backend is not reachable. Check if the service is running and the URL/port is correct.

Changes after editing printers do not take effect The integration reloads automatically after saving. If not, restart Home Assistant manually.
