Flash LumiGate

Art-Net / sACN (E1.31) → DMX512 gateway for ESP32. Flash it straight from this page — no install, no command line.

Not just another Art-Net node: LumiGate is a node plus a live diagnostic tool. Watch all 512 channels update in real time in your browser, get a warning the moment two consoles fight over a universe, see per-sender FPS and frame jitter, and drive galvanically-isolated DMX out. Fully open source, builds for a few dollars.

Pick your board and click flash. The firmware is always the latest release.

Before you start

Use desktop Chrome or Edge. Web Serial does not work in Safari, Firefox, or any mobile browser.
Connect the board over USB, click flash, then pick its serial port in the dialog.
The installer offers an Erase device option. Leave it unchecked to keep your saved config (universe, WiFi, labels); check it for a fully clean install.

If it fails to connect, put the board in download mode manually, then retry: hold BOOT, tap EN/RST, release BOOT.

WT32-ETH01: this board has no USB port, so browser flashing needs an external USB-to-serial (3.3 V TTL) adapter wired to TXD0 / RXD0 / GND, with IO0 pulled to GND while you tap EN to enter download mode. If you would rather not, use the scripted esptool method instead.

After flashing

Press EN/RST to boot.
WiFi builds: the device opens an access point named DMX-Gateway (no password). Connect to it, pick your network in the captive portal, and save.
WT32-ETH01: plug in Ethernet and power. DHCP assigns an IP automatically.
Open http://dmx-gateway.local (or the IP on the serial monitor at 115200 baud) for the live status page.
