I Built a 3,000-LED Smart Wall (WLED, Dig Octa, Home Assistant)

Most people add a light strip behind their TV.
I permanently built over 3,000 addressable LEDs into my walls — powered by a 1500-watt power supply, controlled by WLED, and fully integrated into Home Assistant.

This video is the full technical deep dive behind the LED wall that went viral on TikTok — but this time I’m covering the part everyone actually asks about:

• Planning & layout math
• Power injection & voltage drop
• Wiring strategy & safety
• Dig Octa controller setup
• WLED configuration
• Real-world soldering lessons
• Kitchen accent wall expansion
• Wall-mounted Home Assistant control tablet
