Hey everyone,

We wanted to share an open source project I built: VTally-32, an Arduino firmware that turns an ESP32 (or ESP32-S3) into a WiFi tally light for vMix.
The core idea is straightforward: an ESP32 + a WS2812B NeoPixel LED, and you've got a wireless tally light for just a few bucks. Designed for this board : https://www.waveshare.com/esp32-s3-matrix.htm
But I wanted to push it a bit further with some practical features:
What it does:

  • Native TCP connection to vMix on port 8099 (official protocol), with automatic reconnection and exponential backoff
  • Embedded web UI to configure everything without touching the code (vMix IP, input number, colors, brightness...)
  • mDNS support: reach your tallies at http://tally-name.local
  • AP + STA mode for first-time setup and fallback
  • OTA updates directly from the web interface
  • Built-in diagnostics page
  • ESP32 and ESP32-S3 binaries auto-generated via GitHub Actions on every release

Getting started:

No Arduino IDE needed — ready-to-flash .bin files are available directly in the GitHub releases. Just flash and connect to the AP to configure.
GitHub repo: https://github.com/lfpoulain/VTally-32
Feel free to report bugs or suggestions via GitHub Issues.
