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:

Metric	Descripció	Typical Range
Battery Level	Charge percentage	0–100%
Voltage	Battery voltage	3.0–4.2V (LiPo)
Channel Utilization	% of airtime used locally	0–100%
Air Utilization TX	% of airtime used by this node	0–100%
Uptime	Seconds since last boot	Varies

Environment Sensors

Supported environmental sensors:

Temperature & Humidity

Sensor	Temperature	Humidity	Pressure	Notes
BME280	✓	✓	✓	Recommended all-in-one
BME680	✓	✓	✓	Adds gas resistance/IAQ
SHT31	✓	✓	—	High accuracy
MCP9808	✓	—	—	Precision temperature
LPS22	—	—	✓	Pressure only

Air Quality

Sensor	Metric	Notes
BME680	Gas Resistance / IAQ	Volatile organic compounds
PMSA003I	PM1.0, PM2.5, PM10	Particulate matter
SEN55	PM, NOx, VOC, Temp, Humidity	Multi-sensor

Light & UV

Sensor	Metric
OPT3001	Ambient light (lux)
VEML7700	Ambient light (lux)
LTR390	UV index

Power Metrics

Nodes with INA-series power sensors can report:

Metric	Descripció
Bus Voltage	Supply rail voltage
Current	Power consumption (mA)
Power	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.

Recommended Intervals

Use Case	Device (s)	Environment (s)
Urban mesh (many nodes)	3600	3600
Rural mesh (few nodes)	900	900
Weather station	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.

Troubleshooting

• 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.
