Телеметрия & Сензори

Meshtastic nodes can collect and share sensor data across the mesh network.

Преглед

Telemetry allows nodes equipped with sensors to broadcast environmental, power, and device health information. This data is visible on the node detail screen and can be logged over time.

Device Telemetry

All Meshtastic nodes report basic device telemetry:

Метрични Описание Типичен диапазон
Ниво на батерията Charge percentage 0–100%
Напрежение Напрежение на батерията 3.0–4.2V (LiPo)
Използване на канала % of airtime used locally 0–100%
Air Utilization TX % of airtime used by this node 0–100%
Време на работа Seconds since last boot Varies

Показатели на мощност

Nodes with INA-series power sensors can report:

Метрични Описание
Bus Voltage Supply rail voltage
Текущ Power consumption (mA)
Захранване Calculated power (mW)

Useful for monitoring solar charging or battery health on remote nodes.

Configuring Telemetry

  1. Navigate to Settings → Module Config → Telemetry.
  2. Set reporting intervals:
    • Device Metrics Interval — how often to broadcast device metrics
    • Environment Metrics Interval — how often to broadcast sensor data
  3. Enable specific sensor types as needed.
Use Case Device (s) Environment (s)
Urban mesh (many nodes) 3600 3600
Rural mesh (few nodes) 900 900
Метеорологична станция 900 300
Battery conservation 7200 7200

⚠️ Note: Shorter intervals increase airtime usage and battery drain across the mesh.

Viewing Telemetry

  1. Navigate to Nodes and select a node.
  2. Telemetry sections show on the detail screen:
    • Device Metrics (always available)
    • Environment Metrics (if sensors present)
    • Power Metrics (if INA sensor present)
  3. Historical graphs show trends over time.

Telemetry actions

Отстраняване на неизправности

  • No environment data showing? The remote node needs a physical sensor connected (e.g., BME280 on I2C). Device telemetry (battery, uptime) is always available, but environment metrics require hardware.
  • Stale readings? Check the reporting interval — very long intervals (7200s+) mean data updates infrequently. Also verify the remote node is still online.
  • Sensor conflict on I2C bus? Some sensors share I2C addresses. If you have multiple sensors on the same bus, check for address collisions in the radio’s serial debug output.
