Tally Bridge
Multi-source tally aggregator with a browser and mobile-friendly web UI. Watches one or more tally sources and shows program, preview, and ISO state in real time, on any device on the LAN.
TALLY BRIDGE // V1
The Tally Bridge is a small fanless device that aggregates tally state from one or more sources and exposes it as a real-time web UI any phone, tablet, or laptop on the LAN can open.
What it actually does
- Reads tally state from ATEM switchers, TSL UMD streams, or a Q-SYS JSON feed (or any combination of those)
- Pushes updates to connected browsers over SocketIO with sub-100ms latency on a typical LAN
- Shows program, preview, and ISO state per source on a card-based grid that scales from a phone to a large display
- Light and dark themes, brand-aware
- Optional GPIO triggers for traditional tally lamps
Why a bridge
Modern productions pull tally from several places: a switcher, a graphics box, a NDI-aware Q-SYS design, sometimes all three. Stitching that together into a single, glanceable display is exactly the kind of work nobody wants to do twice. The Tally Bridge does it once, well, and keeps doing it.
