DEJA.js Monitor
Deep diagnostic visibility. Built for technical operators and layout builders who need to see the data flowing across their network.
Core Capabilities
๐ Command Traces
View raw and parsed DCC-EX API commands in real-time. Understand exactly what bytes are being transmitted between the server and the CommandStation.
๐ Live Telemetry
Monitor track power draw, main/prog track statuses, and server uptime metrics from a unified dashboard.
๐ก Sensor Activity
Watch layout events flow in as trains pass sensors. Ideal for verifying automation hardware installations and routing logic.
๐ Event Filtering
Cut through the noise. Filter the event stream strictly by turnouts, locos, errors, or custom IO devices to debug specific layout zones.

Clear the fog.
When hardware doesn't react as expected, guessing isn't an option. DEJA.js Monitor replaces cryptic serial logs with a designed, structured view of your layout's state.
- Color-coded log severity (Info, Warn, Error)
- Timestamped event history
- Immediate feedback on route execution
