# Node Metrics
|
||
|
||
The node detail screen provides comprehensive telemetry and metrics for each node on your mesh.
|
||
|
||
## Метрика уређаја
|
||
|
||
Basic operating information reported by each node:
|
||
|
||
| Метрика | Опис |
|
||
| -------------------- | ----------------------------------- |
|
||
| Ниво батерије | Current battery percentage |
|
||
| Напон | Battery voltage reading |
|
||
| Искоришћеност канала | Percentage of airtime consumed |
|
||
| Време емитовања | Transmission time used by this node |
|
||
| Време рада | 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.
|
||
|
||
## Метрике сензора
|
||
|
||
Environmental sensor data (requires compatible hardware):
|
||
|
||
| Метрика | Sensor Examples |
|
||
| ------------------------------------ | --------------------- |
|
||
| Температура | BME280, BME680, SHT31 |
|
||
| Влажност | BME280, BME680, SHT31 |
|
||
| Барометарски притисак | 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.
|
||
|
||
> 💡 **Tip:** Environment metrics require a sensor connected to the remote node. Not all nodes report environmental data. See [Telemetry & Sensors](telemetry-and-sensors) for a full list of supported sensors.
|
||
|
||
## Signal Metrics
|
||
|
||
Radio signal quality information:
|
||
|
||
| Метрика | Опис |
|
||
| --------- | ----------------------------------------------------------------------------- |
|
||
| SNR | Signal-to-Noise Ratio (higher is better) |
|
||
| RSSI | Received Signal Strength Indicator (closer to 0 is better) |
|
||
| Hop Count | Number of mesh hops for last message |
|
||
|
||
### Signal Quality Reference
|
||
|
||
| SNR Range | Quality |
|
||
| --------------------------------- | ---------- |
|
||
| > 10 dB | Excellent |
|
||
| 0 to 10 dB | Добро |
|
||
| -10 to 0 dB | Прихватљив |
|
||
| < -10 dB | Poor |
|
||
|
||
## Мерни подаци о снази
|
||
|
||
Power management telemetry (requires INA sensor or compatible hardware):
|
||
|
||
| Метрика | Опис |
|
||
| ----------- | ----------------------- |
|
||
| Bus Voltage | Supply voltage |
|
||
| Струја | Power draw in milliamps |
|
||
| Снага | Calculated wattage |
|
||
|
||
## Праћење руте
|
||
|
||
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.
|
||
|
||
## Логови позиција
|
||
|
||
Historical position data for nodes that share their location:
|
||
|
||
- GPS coordinates
|
||
- Висина
|
||
- Speed (if moving)
|
||
- 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:
|
||
|
||
|
||
|
||
> ⚠️ **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.
