Node Metrics
The node detail screen provides comprehensive telemetry and metrics for each node on your mesh.
Device Metrics
Basic operating information reported by each node:

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.
The BME680 IAQ (Indoor Air Quality) index is a single 0โ500+ value derived from gas resistance, shown against a color-coded scale from Excellent to Dangerously Polluted:
โ ๐ก 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:
โข Select a time frame for the charts.
โข Filter with metric chips โ only metrics that have data are shown.
โข Refresh / request the latest air-quality telemetry.
โข Export to CSV for analysis in a spreadsheet.
โ ๐ก 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.
Signal Metrics

Signal Quality Reference
Signal quality is rated from SNR relative to the active LoRa modem preset's demodulation floor, not from fixed thresholds โ a given SNR means different things on different presets (e.g. โ15 dB is fine on LongSlow but unusable on ShortFast). RSSI is shown but is not part of the rating. Letting T383838limit be the preset's SNR limit:

โ Good โ SNR above the preset's limit โ
โ Fair โ less than 5.5 dB below the limit โ
โ Bad โ 5.5 dB to 7.5 dB below the limit โ
โ None โ more than 7.5 dB below the limit โ

See Understanding the Signal Meter for the full explanation.
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
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

Each hop represents a relay node that forwarded the message.

Historical position data for nodes that share their location:
โข GPS coordinates
โข Altitude
โข Speed (if moving)
โข 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:
โ โ ๏ธ Note: Metrics are only available when they have been reported by the remote node. Metrics
โ update at intervals configured on each node's telemetry settings.
