Add a Sensors: list to config.yaml. Each entry names an EnvironmentMetrics
field and a shell command that prints one number:
Sensors:
- Type: temperature
Command: cat /sys/bus/iio/devices/iio:device0/in_temp_input
Scale: 0.001
- CommandSensor plugs into EnvironmentTelemetryModule like the T1000x
sensor (no I2C device). Readings are cached for 30s, since getMetrics()
also runs for screen refreshes and phone requests. Output that is not
exactly one finite number is logged and the field is left unset.
Integer fields are rounded and clamped.
- Type matches the protobuf field name, case-insensitively. An unknown
Type or missing Command stops meshtasticd, as Security.AdminKeys does.
Entries append across config.d files.
- exec() now has a timeout: commands run in their own process group,
stdin is /dev/null, and the whole group is killed at the deadline, so
a hung script stalls the main loop for a bounded time. Command sensors
get 2s; HostMetrics and other exec() callers get 10s. Output is capped
at 4 KiB. Windows keeps popen() without a timeout.
- --check validates the section (type, command, scale, unknown keys,
duplicate types) and notes that sensors need environment measurement
enabled. Boot logs a warning when sensors are configured but
environment measurement is off. The section does not enable telemetry
itself, because enabling it also broadcasts to the mesh.

Meshtastic Firmware
Overview
This repository contains the official device firmware for Meshtastic, an open-source LoRa mesh networking project designed for long-range, low-power communication without relying on internet or cellular infrastructure. The firmware supports various hardware platforms, including ESP32, nRF52, RP2040/RP2350, and Linux-based devices.
Meshtastic enables text messaging, location sharing, and telemetry over a decentralized mesh network, making it ideal for outdoor adventures, emergency preparedness, and remote operations.
