I have a laser cutter in my office that I use from time to time. I close the door when its running because you need safety glasses on while its running, but since I use my office for other things, the door closed doesn’t necessarily mean safety glasses are needed. To make this simpler, I decided to try and make some automations to notify when the laser is running. I want to use a WLED strip around the door and light it different colors based on laser operating status (and other statuses in the future).

- Set the WLED strip to red when the laser starts cutting
- Set the WLED strip to the previous settings (or turn it off) when the laser stops cutting
I was able to get WLED going on a light strip but I do have a lack of ideas on how to make use of it. I finally decided to go with the tried and true movie lighting. So my goal is to setup automations so that when my Roku begins playing something, the WLED strip dims and sets to a specific color (we’ll go with red), and when I pause or stop playing, it will turn to max brightness white light. This will give lower lighting while watching and brighter lights if something is paused (and I have to go get something). I’m still not entirely sure if I will end up making use of this in the end, but it will give me some ideas on what I can do and how to do it.

Integrating WLED into Home Assistant is a relatively simple task.
- Go to the integrations page on home assistant
- Add a new integration and search for WLED
- Add the ip
After the, you’re good to go. Home Assistant will show the unit as a number of entities, a light and a number of switches.

I found a guide for running WLED on an ESP8266 micro controller to drive individually addressable RGB cables. I thought this would be a fun little project after working with the smart plugs and home assistant automations. Since WLED is another FOSS and cloud-free project, this still fits with my whole fully self hosted smart home ideal. Since no project is fool proof and I have run into small problems when working on the project.
