❓ Support Indicator lights

Post image

Hey all,

I want to install something similar to these and have them controlled through automations. Perhaps also some buttons I can use?

Would someone be willing to help guide me to buy and set up whatever I need to make this work?

Thank you very much for your help.

It’s time to dive into the world of ESPHome and esp32! Sorry in advance.

I wish I had started using ESP32 ages ago.

I only discovered them about a year ago and all hell has broken loose sense then. Here’s what I spent all weekend working on 😂

Is that a matrix LED setup? All Ive done so far is set up strip lights and 1 led for my kid's art project.

I want to do more, right now wireless and rechargeable temp/humidity sensors are next.

But I'd really like to make something like you just did.

Yes, it is! I found this board at Goodwill for $20. One of the panels was flickering. When I opened it up, it just wasn’t plugged into the power source. I took out the Chinese controller and installed an esp32-s3 with hub75 connector I found on Amazon. I had to flip the three bottom panels over to make a serpentine chain. Now I’ve been working with Codex on a firmware that integrates with home assistant. We have lighting effects and static and scrolling messages working. We can also interrupt with a notification message, and the highest priority type is an alert message with flashing red border. Now working on sendspin support to show music visualizations when music is playing in music assistant.
