Feature Request: Local API to Access Printer Data Already Used by Panda Touch

[Lionsit]

First of all, thank you for the great work on Panda Touch. It is an extremely useful and well-designed addition to the Bambu Lab ecosystem.
I would like to propose a local API that allows read-only access to the printer data already displayed by Panda Touch.

Currently, Panda Touch retrieves printer data via the Bambu Lab Cloud. Since this data is already available on the device, exposing it through a local web API (HTTP / WebSocket) would enable many DIY and integration projects without requiring users to directly connect to the Bambu Lab Cloud API themselves.

This would have several advantages:
Avoids reverse-engineering or unofficial Cloud API usage
Prevents potential conflicts or connection issues with Panda Touch’s own Cloud connection
Keeps access strictly read-only for safety

Below is a list of data that Panda Touch already seems to have access to and that would be highly useful if exposed locally.

1. Print State
   status
   idle
   printing
   paused
   completed
   error
   sub_status (e.g. homing, heating, layer_change)
   current_task_id

2. Progress
   progress_percent
   current_layer
   total_layers
   elapsed_time
   remaining_time_estimate

3. Temperature & Sensors
   Hotend / Bed
   nozzle_temp
   nozzle_target
   bed_temp
   bed_target
   Environment
   chamber_temp (if Panda Sense is connected)
   ambient_temp

4. Mechanics & Actuators
   Fans

part_fan_speed
aux_fan_speed
chamber_fan_speed

Axes
xyz_position (even partially abstracted would be useful)

LED
led_mode

5. Current Job Metadata
   job_name
   gcode_name
   source
   cloud
   sd_card
   bambu_studio
   start_time
   estimated_time
   file_size
   layer_height
   nozzle_diameter

Summary

A local, read-only API would greatly increase Panda Touch’s value for power users and makers, while keeping security and stability intact.
Since Panda Touch already consumes this data, exposing it locally would be a clean and elegant solution.
Thank you for considering this feature!
