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:
| Metric | Description |
|---|---|
| Battery Level | Current battery percentage |
| Voltage | Battery voltage reading |
| Channel Utilization | Percentage of airtime consumed |
| Airtime | Transmission time used by this node |
| Uptime | Time since last reboot |
Device metrics are displayed as individual cards with trend sparklines showing battery level, voltage, channel utilization, airtime, and uptime over time.
💡 Tip: Tap any metric card to expand it into a full chart with historical data points. Pinch to zoom the time axis.
Environment Metrics
Environmental sensor data (requires compatible hardware):
| Metric | Sensor Examples |
|---|---|
| Temperature | BME280, BME680, SHT31 |
| Humidity | BME280, BME680, SHT31 |
| Barometric Pressure | BME280, BMP280 |
| Gas Resistance | BME680 |
| IAQ (Air Quality) | BME680 |
Environment metrics are charted over time for easy trend analysis — 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 0–500+ value derived from gas resistance, shown against a color-coded scale from Excellent to Dangerously Polluted:
💡 Tip: Environment metrics require a sensor connected to the remote node. Not all nodes report environmental data. See Telemetry & Sensors 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 CO₂ sensor. It is separate from the BME680 IAQ reading listed under Environment Metrics — IAQ is a single gas-resistance-derived index, while the Air Quality view charts the underlying particulate and CO₂ measurements.
| Metric | Unit | Description |
|---|---|---|
| PM1.0 | µg/m³ | Particulate matter up to 1.0 micron |
| PM2.5 | µg/m³ | Particulate matter up to 2.5 microns |
| PM10 | µg/m³ | Particulate matter up to 10 microns |
| AQI | EPA index | EPA NowCast AQI computed from your recent PM2.5 history, with a color-coded severity label. Shown next to PM2.5 once enough readings have accumulated. |
| CO₂ | ppm | Carbon dioxide concentration |
| CO₂ temperature | °C / °F | Temperature reported by the CO₂ sensor itself (e.g. SCD4x) |
| CO₂ humidity | % | Relative humidity reported by the CO₂ sensor |
CO₂ readings are color-coded by severity to make air quality easy to read at a glance:
| Band | CO₂ Range (ppm) | Color |
|---|---|---|
| Good | < 1000 | Green |
| Stuffy | < 2000 | Amber |
| Poor | < 5000 | Orange |
| Unsafe | < 30000 | Red |
| Evacuate | ≥ 30000 | Dark red |
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:
- Select a time frame for the charts.
- Filter with metric chips — only metrics that have data are shown.
- Refresh / request the latest air-quality telemetry.
- Export to CSV for analysis in a spreadsheet.
💡 Tip: Air Quality metrics require a compatible air-quality sensor on the remote node. If a node has no particulate or CO₂ sensor, the air-quality button won't appear. See Telemetry & Sensors for supported hardware.
Signal Metrics
Radio signal quality information:
| Metric | Description |
|---|---|
| SNRSNR (Signal-to-Noise Ratio). A measure used in communications to quantify the level of a desired signal to the level of background noise. In Meshtastic and other wireless systems, a higher SNR indicates a clearer signal that can enhance the reliability and quality of data transmission. | Signal-to-Noise RatioSNR (Signal-to-Noise Ratio). A measure used in communications to quantify the level of a desired signal to the level of background noise. In Meshtastic and other wireless systems, a higher SNR indicates a clearer signal that can enhance the reliability and quality of data transmission. (higher is better) |
| RSSIRSSI (Received Signal Strength Indicator). The raw power level of a received signal, where a value closer to zero is stronger. Clients rate signal quality from SNR rather than RSSI. | Received Signal Strength Indicator (closer to 0 is better) |
| Noise Floor | Local background RFRF (Radio Frequency). The radio signal a node transmits and receives over LoRa. noise in dBm (more negative is quieter) |
| Hop Count | Number of mesh hops for last message |
Signal Quality Reference
Signal quality is rated from SNRSNR (Signal-to-Noise Ratio). A measure used in communications to quantify the level of a desired signal to the level of background noise. In Meshtastic and other wireless systems, a higher SNR indicates a clearer signal that can enhance the reliability and quality of data transmission. relative to the active LoRaLoRaA low-power, long-range wireless communication technology used by Meshtastic devices to enable communication over distances of several kilometers without the need for cellular, Wi-Fi, or other traditional network infrastructures. modem preset's demodulation floor, not from fixed thresholds — a given SNRSNR (Signal-to-Noise Ratio).

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 RFRF (Radio Frequency). The radio signal a node transmits and receives over LoRa. 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.
Power Metrics
Power management telemetry (requires INA sensor or compatible hardware):
| Metric | Description |
|---|---|
| Bus Voltage | Supply voltage |
| Current | Power draw in milliamps |
| Power | Calculated wattage |
Traceroute
Traceroute shows the path a message takesTAK (Team Awareness Kit). A situational awareness ecosystem. Meshtastic bridges to it by converting mesh messages to and from Cursor on Target format. through the mesh:
- From the node detail screen, tap Traceroute.
- The app sends a traceroute request to the target node.
- Results show each hop with SNRSNR (Signal-to-Noise Ratio). A measure used in communications to quantify the level of a desired signal to the level of background noise. In Meshtastic and other wireless systems, a higher SNR indicates a clearer signal that can enhance the reliability and quality of data transmission./RSSIRSSI (Received Signal Strength Indicator). The raw power level of a received signal, where a value closer to zero is stronger. Clients rate signal quality from SNR rather than RSSI. values.
Reading Traceroute Results
You → Node A (SNR: 8.5) → Node B (SNR: 5.2) → Target
Each hop represents a relay node that forwarded the message.
Position Log
Historical position data for nodes that share their location:
- GPSGPS (Global Positioning System). A satellite positioning system. A node with a GPS module determines its own location and can report that position to the mesh. coordinates
- Altitude
- Speed (if moving)
- Timestamp for each position report
Neighbor Info
Shows which nodes a given node can directly hear, useful for understanding mesh topology.

The position tab shows location data for nodes that share GPSGPS (Global Positioning System). A satellite positioning system. A node with a GPS module determines its own location and can report that position to the mesh.:
⚠️ Note: Metrics are only available when they have been reported by the remote node. Metrics update at intervals configured on each node's telemetry settings.
