# Sõlme mõõdikud

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

## Seadme mõõdikud

Basic operating information reported by each node:

| Meetriline     | Kirjeldus                           |
| -------------- | ----------------------------------- |
| Battery Level  | Current battery percentage          |
| Vool           | Battery voltage reading             |
| Kanali kasutus | Percentage of airtime consumed      |
| Airtime        | Transmission time used by this node |
| Töötamise aeg  | 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.

> 💡 **Vihje:** Puuduta mis tahes mõõdikukaarti, et laiendada see ajalooliste andmepunktidega täisdiagrammiks. Ajatelje suumimiseks näpista sõrmed kokku.

## Keskkonnamõõdikud

Environmental sensor data (requires compatible hardware):

| Meetriline                           | Sensor Examples       |
| ------------------------------------ | --------------------- |
| Temperatuur                          | BME280, BME680, SHT31 |
| Niiskus                              | BME280, BME680, SHT31 |
| Baromeetri rõhk                      | BME280, BMP280        |
| Gaasi surve                          | 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_:

![IAQ index scale from Excellent to Dangerously Polluted](../../assets/screenshots/node-metrics_iaq_scale.png)

> 💡 **Vihje:** Keskkonnamõõdikute jaoks on vaja kaugsõlmega ühendatud andurit. Not all nodes report environmental data. Vaata [Telemeetria & Sensorid](telemetry-and-sensors), et näha toetatud andurite täieliku loendit.

## 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.

| Meetriline            | Unit  | Kirjeldus                                            |
| --------------------- | ----- | ---------------------------------------------------- |
| 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                  |
| CO₂                   | ppm   | Süsinikdioksiidi kontsentratsioon                    |

CO₂ readings are color-coded by severity to make air quality easy to read at a glance:

| Band         | CO₂ Range (ppm) | Värv        |
| ------------ | ---------------------------------- | ----------- |
| Hea          | < 1000    | Roheline    |
| Stuffy       | < 2000    | Merevaik    |
| Kehv         | < 5000    | Oranž       |
| Ebaturvaline | < 30000   | Punane      |
| Evakueeru    | ≥ 30000                            | Tume punane |

![Air quality readings with color-coded CO₂ severity](../../assets/screenshots/node-metrics_air_quality.png)

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.
- **Ekspordi CSV** analüüsimiseks arvutustabeli vaates.

> 💡 **Vihje:** Õhukvaliteedi mõõdikute jaoks on vaja kaugsõlmega ühendatud andurit. If a node has no particulate or CO₂ sensor, the air-quality button won't appear. Vaata [Telemeetria & Sensorid](telemetry-and-sensors) toetatud raudvara kohta.

## Signaali mõõdikud

Radio signal quality information:

| Meetriline  | Kirjeldus                                                                      |
| ----------- | ------------------------------------------------------------------------------ |
| SNR         | Signal-to-Noise Ratio (higher is better)                    |
| RSSI        | Received Signal Strength Indicator (closer to 0 is better)  |
| Noise Floor | Local background RF noise in dBm (more negative is quieter) |
| Hop Count   | Number of mesh hops for last message                                           |

### Signal Quality Reference

Signal quality is rated from **SNR relative to the active LoRa modem preset's demodulation floor**, not from fixed thresholds — a given SNR means different things on different presets (e.g. −15 dB is fine on LongSlow but unusable on ShortFast). RSSI is shown but is not part of the rating. Letting `limit` be the preset's SNR limit:

| Quality  | Criteria                                         |
| -------- | ------------------------------------------------ |
| Hea      | SNR above the preset's limit                     |
| Rahuldav | within 5.5 dB below the limit    |
| Halb     | within 7.5 dB below the limit    |
| Puudub   | more than 7.5 dB below the limit |

See [Understanding the Signal Meter](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. Kasuta **Taotle**, et küsida ühendatud raadiost uut kohaliku statistika telemeetriaaruannet, **Tühjenda**, et eemaldada selle sõlme kohaliku statistika logi ja **Salvesta**, et salvestada nähtavat kohaliku statistika ajalugu CSV-failina.

## Võimsusnäitajad

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

| Meetriline  | Kirjeldus               |
| ----------- | ----------------------- |
| Bus Voltage | Supply voltage          |
| Pinge       | Power draw in milliamps |
| Toide       | Calculated wattage      |

## Marsruudi

Traceroute shows the path a message takes through the mesh:

1. Sõlme üksikasjade ekraanil puuduta **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.

## Asukoha logi

Historical position data for nodes that share their location:

- GPS coordinates
- Kõrgus
- Speed (if moving)
- Timestamp for each position report

## Naabruse teave

Shows which nodes a given node can directly hear, useful for understanding mesh topology.

## Viewing Metrics

1. Mine **Seadmed**.
2. Puuduta sõlme, mida soovite kontrollida.
3. Select the metric category from the detail tabs.

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

![Asukoha tekstisisene sisu](../../assets/screenshots/nodes_position.png)

> ⚠️ **Märkus:** Mõõdikud on saadaval ainult siis, kui need on kaugsõlme poolt esitatud. Mõõdikud värskendatakse iga sõlme telemeetria sätetes seadistatud intervallidega.
