Home Assistant NRE.Com.Net Add-On: SnapMaker Monitor

About

This add-on runs a python script, which collects the the current status from the Snapmaker 2.0 3D-Printer API and sends it to a Home Assistant webhook.

I refactored and modified the original version of the script from NiteCrwlr

thx for this.
Is thiscompatible with the new SNapMaker U1

I tried it and it doesn’t seem to work. I get a “Set IP not reachable, retrying in 1 minutes” error. AFAIC the port of the snapmaker is regular port 80 and not 8080 (this is the default in the configuration). If i try to start the addon with this port, I get this error message: Request failed: 404 Client Error: Not found for url: http://PRINTER_IP:80/api/v1/connect"
I think the U1 uses a different API for communication.

not tested my self but maybe you have to activate “LAN Mode” on the device?

You can use the hacs moonraker addon for snapmaker U1, see here: GitHub - marcolivierarsenault/moonraker-home-assistant: Home Assistant integration for Moonraker, Klipper and Mainsail

Working here for my U1.

You have to manually configure the:

Camera Url: http:///webcam/stream.mjpg
Snapshot URL: http:///webcam/snapshot.jpg

lordfiSh · February 11, 2026, 12:13pm

Data working fine, what is the Webcam url?
http://myip:7125/snapshot.jpg
just get me a 404 not found

Looks like, you need to a bit more to get it working: How to enable webcam streaming on the Snapmaker U1 | SimplyPrint Helpdesk

I have left Camera and Snapshot URL at default (empty) and yes than it don’t work.

I have installed the paxx12 cfw on the printer and than you can see the available streams here: http://IP/webcam/

Played with all and the motion jpeg causes serious performance issues in the browser when using it.
Also tried to add the various streames to go2rtc or in HA as generic camera. Nothing does work reliable.

What worked is the custom webrtc camera card from HACS with this:

type: custom:webrtc-camera
url: rtsp://192.168.0.12:8554/stream
ui: true

For the rtsp to work you have to enable rtsp in extended firmware-config, Todo this to the following:

On the printer touch screen enable “Advanced Mode”
Goto http://IP/firmware-config/ and enable rtsp

The stream works good, sometimes it freezes shortly but comes back. Also over mobile data it works.

And for reference here is my complete card:

Hi,
found this integration on the web:
kbaker827/ha-snapmaker-u1
that version did not allow to enable/disable the light, nor was it possible to trigger camera to update for a bit.
So I forked the code and had AI add the necessary code to do that. It is not perfect (no read-back of light state, so a toggle is needed…) but the camera works.
The updates version can be found here:
HMeuleman/ha-snapmaker-u1: Snapmaker U1 Integration for Home Assistant
Use HACS and add the repository, download it, restart home assistant then add integration snapmaker. Fill in the IP address and the name you want to use and it should work.
I’ve chosen to accept the timeout of the camera and have it stop after some time as that is fine for how I want to use it. Of course a simple yaml can be added to retrigger the camera if you want that. Camera is still 1 fps !!

If you want you can add manual camera:
“http://10.0.0.123/server/files/camera/monitor.jpg”
where 10.0.0.123 should be replaced with IP address of 3d printer. Use frame rate of 1. Add it as integration and then display it where you want.

Now I can watch my printer status even when I’m not home!! while printer is configured for LAN mode.

Note: this was tested with FW 1.1.1 on U1, will be updating that tonight, hope it still works.

Spectacular, could you share the code? Thank you.
