Node Metrics

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

裝置計量資料

Basic operating information reported by each node:

公制（公里/公尺） 描述說明
Battery Level Current battery percentage
電壓 Battery voltage reading
頻道使用量 Percentage of airtime consumed
Airtime Transmission time used by this node
運行時間 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.

環境計量資料

Environmental sensor data (requires compatible hardware):

公制（公里/公尺） Sensor Examples
溫度 BME280, BME680, SHT31
濕度 BME280, BME680, SHT31
大氣壓力 BME280, BMP280
氣體感測器 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.

💡 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.

Signal Metrics

Radio signal quality information:

公制（公里/公尺） 描述說明
SNR Signal-to-Noise Ratio (higher is better)
RSSI Received Signal Strength Indicator (closer to 0 is better)
跳躍次數 Number of mesh hops for last message

Signal Quality Reference

SNR Range Quality
> 10 dB Excellent
0 to 10 dB 良好
-10 to 0 dB 普通
< -10 dB Poor

電源計量資料

Power management telemetry (requires INA sensor or compatible hardware):

公制（公里/公尺） 描述說明
Bus Voltage Supply voltage
目前 Power draw in milliamps
電力 Calculated wattage

路由追蹤

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 

You → Node A (SNR: 8.5) → Node B (SNR: 5.2) → Target

Each hop represents a relay node that forwarded the message.

定位日誌

Historical position data for nodes that share their location:

  • GPS coordinates
  • 海拔高度
  • Speed (if moving)
  • Timestamp for each position report

鄰近節點資訊

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.

Node detail — local device

The position tab shows location data for nodes that share GPS:

⚠️ 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.
