Telemetry & Sensors
Meshtastic nodes can collect and share sensor data across the mesh network.
Overview
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:

Configuring Telemetry
1. Navigate to Settings β Module Config β Telemetry.
2. Set reporting intervals:
β’ Device Metrics Interval β how often to broadcast device metrics
β’ Environment Metrics Interval β how often to broadcast sensor data
3. Enable specific sensor types as needed.

Viewing Telemetry
1. Navigate to Nodes and select a node.
2. Telemetry sections show on the detail screen:
β’ Device Metrics (always available)
β’ Environment Metrics (if sensors present)
β’ Power Metrics (if INA sensor present)
3. Historical graphs show trends over time.
Troubleshooting
β’ 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.
β’ Stale readings? Check the reporting interval β very long intervals (7200s+) mean data updates infrequently. Also verify the remote node is still online.
β’ 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.
