Node Metrics
The node detail screen provides comprehensive telemetry and metrics for each node on your mesh.

Traceroute shows the path a message takes through the mesh:
1. From the node detail screen, tap Traceroute.
2. The app sends a traceroute request to the target node.
3. Results show each hop with SNR/RSSI values.

Each hop represents a relay node that forwarded the message.

Historical position data for nodes that share their location:
β’ GPS coordinates
β’ ΠΠΈΡΠΈΠ½Π°
β’ Speed (if moving)
β’ Timestamp for each position report
Neighbor Info
Shows which nodes a given node can directly hear, useful for understanding mesh topology.
Viewing Metrics
1. Navigate to Nodes.
2. Tap the node you want to inspect.
3. Select the metric category from the detail tabs.
The position tab shows location data for nodes that share GPS:
