Guide: Raspberry Zero + Home Assistant as Webcam for PrusaConnect

Hi all,

since I had some trouble to get my Raspberry Pi Zero 2 W working as a webcam for PrusaConnect, I thought I write a guide for you to do better...

 

This is what you need:

  • Raspberry Pi Zero 2 W
  • Raspberry Pi Camera Module 2.1 or 3
  • Raspberry USB Charger
  • SD Card
  • Home Assistant server running

This is what you need to do:

Step 1: Get Raspberry Pi Zero 2 W and camera running

  • Connect the camera module with Raspberry Pi Zero 2 W
  • Install the latest Raspberry Pi OS Light Version on the SD card by using the Raspberry Imager -> https://www.raspberrypi.com/software/
  • Check the IP adress of your Raspberry Pi Zero 2 W using a network scanner or your router user interface
  • Once the OS is installed you need to enable the legacy camera support using a ssh connection and then the command "sudo raspi-config"

 

Step 2: Install MJPEG streamer

 

Step 3: Get token and fingerprint from PRusaConnect

  • Login to PrusaConnect, go to camera, add a new camera
  • Click on the qr code - use your computer as camera and start the stream
  • Now use the developer menu of your browser (recommend: Chrome Browser) to get the token and fingerprint values

 

Step 4: Use Home Assistant to push still images to PrusaConnect

  • You can use your existing Home Assistant server (will not explain this here)
  • Go to settings -> add on store -> add "Nodered"
  • Once Nodered is installed, you will need to set a password in the configuration tab of Nodered -> then start Nodered. Make sure you selected "Show in tab"
  • Go to NoderedCreate a new flow by dragging "timestamp" + "http request" + "http request" to the workspace area and connect the elements.
  • Now configure the elements:
    timestamp: set the interval to 30 seconds
    http request:  use method "GET" and enter the snapshot URL
    http request: use method "PUT" and enter the URL https://connect.prusa3d.com/c/snapshot
    and the headers
    token + the token value
    fingerprint + the fingerprint value
    content-type + image/jpg

 

Now Home Assistant / Nodered will push a still image every 30 seconds to your PrusaConnect Webcam view...

Nice, I feel that could be used with esp32 as well.

Sounds like Home Assistant is not really used because you use Node-RED to fetch and push image. In that case just installing mqtt server (for example mosquitto) and Node-RED would be sufficient.

See my GitHub and printables.com for some 3d stuff that you may like.

Could someone clarify why the fingerprint value isn't more accessible?
