thermal-sensor-manager-cli

thermal-sensor-manager-cli is a command line developer tool used to query and control the state of the fuchsia.thermal.SensorManager protocol exposed by power-manager.

Unlike low-level, driver-facing temperature CLI tools (like temperature-cli), this tool operates at a higher level (in the bootstrap realm) to list sensors, get their current temperature, and set or clear overrides.

How to Run

This tool is run within the sandbox environment of power-manager using the component explore command.

Launch component explore for power-manager:

$ component explore bootstrap/power_manager

Inside the explore shell, run the tool:

$ thermal-sensor-manager-cli <command> [<args>]

Commands and Examples

1. List Sensors

Lists all temperature sensors exposed by SensorManager.

$ thermal-sensor-manager-cli list
Sensors found: 3
  charger
  cpu
  usb

2. Get Temperature

Retrieves the current temperature for a specific sensor.

$ thermal-sensor-manager-cli read cpu
Sensor 'cpu' temperature: 34.50°C

3. Set Temperature Override

Sets an override temperature for a specific sensor. This forces power-manager to use the overridden value for thermal policy decisions.

$ thermal-sensor-manager-cli override cpu 75.0
Successfully set override for 'cpu' to 75.00°C

4. Clear Temperature Override

Clears any temperature override set on a specific sensor, reverting back to reading the real sensor value.

$ thermal-sensor-manager-cli clear cpu
Successfully cleared override for 'cpu'
