WLED lights for your Bambu Labs 3d printer

Support for adding LED chamber lights via the WLED.

Open your Home Assistant instance and show the blueprint import dialog with a specific blueprint pre-filled.

WLED Features

  • LED lights automatically turn off when Bambu Lida is in use so as to not interfere

  • LED lights turn red when there is an error in the printer

  • LED lights turn blue when bed is auto leveling

  • LED lights turn green when print is finished

im going to give this ago

Will this also turn on the lights with the lights button on the X1 control panel?

added the blueprint, setup the entities, not changing the colours just solid white. does it need additional setup with wled?

Make sure you can fully control your wled strip from home assistant before you try the blueprint

Not currently but it might be able to be added. I’d have to take a look

i can control, but stull when print starts it just stay white all the time

Sorted, your blueprint created the condition attributes with space between the words,
solution to modify and replace spaces to “_” .

Thanks for your great work anyway :+1:

I can not get this to work. Can anyone help? The light will turn on and off with my printers light but thats anout all the automation im getting out of it.

Can anyone help?

Unfortunately, it doesn’t work for me either

Unfortunately same her, it just works for ON/OFF, not taking into account the Lidar operation.

So I seem to have this running w/out issue on one printer. I would like to use a WLED controller I have laying around (Athom) that has two outputs (V/G/D 1 & 2) and I have them set up as segments within WLED

Is there anyway to use this blueprint to have “Printer 1” control SEGMENT 0 and “Printer 2” control SEGMENT 1 on the controller? If not I’ll spin up two esp32s and do it that way - but if I can do it off the one controller it would be great.

The blueprint seems to expect a Device, not entity for the WLED controller so not sure how to work around that

My segments are set up as in the screenshot (Columbia and Magenta are my X1Cs – Rocky Horror for the win!)

My WLED integration in HA is set up :

Hi, thanks for sharing this. Do you have a list of parts you used to implement this?

Anyone able to get this working or is this dead/unusable? Confirmed I can control my WLED in HA on its own but not seeing this causing any color change on the lights when printer is operating.

Thanks for sharing this! Any chance you can add a brightness setting? I’ve found at 100% my camera ends up super washed out by the LEDs.

That is exactly the only thing i missed inside that integration :smiley:

Same here. The only thing that seems to work is the WLED strip turns on/off with the chamber light control. Otherwise I get no lighting changes when printing, nor does it shut off when lidarr is active.
