I’ve been diving into the world of smart home integrations and decided to take my 3D printing setup to the next level. I wanted to add some LED chamber lights to my Bambu Labs 3D printer, and after some research, I stumbled upon the WLED integration in Home Assistant. It turned out to be a perfect fit!
The Setup
I started by installing the WLED integration in Home Assistant. This was straightforward thanks to the detailed documentation available. I connected my WLED-enabled ESP device to the printer’s chamber lights and set up the necessary entities in Home Assistant. The best part was configuring the automation to control the lights based on the printer’s status.
Features I Added
- Automatic Lights Off During Printing: The lights turn off when the printer starts to avoid any interference with the print job.
- Error Alerts: The lights flash red when there’s an error, making it easy to spot issues even from a distance.
- Bed Leveling Indication: Blue lights indicate when the bed is being auto-leveled, giving me a clear visual cue.
- Completion Notification: Green lights signal when the print is done, so I know when to check on my creation.
A Few Hiccups
Initially, I faced some challenges with the RGB color settings. The lights weren’t responding as expected, but after tweaking the automation rules and ensuring the correct entity IDs were used, everything fell into place.
The Blueprint
For anyone interested in replicating this setup, I created a blueprint that automates the entire process. It checks the printer’s status and adjusts the lights accordingly. The blueprint is available on GitHub, and I’ve also shared a YouTube video demonstrating the setup in action.
Final Thoughts
This project has been a fantastic way to enhance my 3D printing experience. It’s not just about the functionality—it’s also about the satisfaction of creating something that seamlessly integrates into my smart home ecosystem. If you’re into both 3D printing and smart home tech, I highly recommend giving this a try!
