Node Metrics

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

Environment metrics are charted over time for easy trend analysis โ€” temperature, humidity, and pressure each get their own line chart with the measurement unit displayed on the Y axis.

โ”‚ ๐Ÿ’ก Tip: Environment metrics require a sensor connected to the remote node. Not all nodes report
โ”‚ environmental data. See Telemetry & โ”‚ Sensors
โ”‚ for a full list of supported sensors.

Air Quality Metrics

Air Quality is a dedicated metrics view for nodes equipped with a particulate-matter and/or COโ‚‚ sensor. It is separate from the BME680 IAQ reading listed under Environment Metrics โ€” IAQ is a single gas-resistance-derived index, while the Air Quality view charts the underlying particulate and COโ‚‚ measurements.

An air-quality log/metrics button appears on the node detail screen only when the node has reported air-quality telemetry. From the Air Quality view you can:

โ€ข Select a time frame for the charts.
โ€ข Filter with metric chips โ€” only metrics that have data are shown.
โ€ข Refresh / request the latest air-quality telemetry.
โ€ข Export to CSV for analysis in a spreadsheet.

โ”‚ ๐Ÿ’ก Tip: Air Quality metrics require a compatible air-quality sensor on the remote node. If a node
โ”‚ has no particulate or COโ‚‚ sensor, the air-quality button won't appear. See Telemetry & โ”‚ Sensors
โ”‚ for supported hardware.

Local Stats from your connected radio are also shown in Signal Quality when available. These logs include noise floor, traffic counters, relay counters, online node counts, and radio uptime. The noise floor chart uses a dashed reference line at -85 dBm to help identify a busy RF environment. Use Request to ask the connected radio for a fresh Local Stats telemetry report, Clear to remove Local Stats logs for that node, and Save to export the visible Local Stats history as CSV.

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.

Reading Traceroute Results
