Environment Variables

Accessory states can be accessed within commands via environment variables which will have the form:

Dummy_[ACCESSORY_ID]_[CHARACTERISTIC]

ACCESSORY_ID will be sanitized to alphanumeric characters only. So, for example "cc5d51b8-40df-4889-89b4-3bbadd3749c0" will become "cc5d51b840df488989b43bbadd3749c0"

CHARACTERISTIC will be one of the following depending on the accessory type:

• Brightness
• LockTargetState
• On
• TargetHeatingCoolingState
• TargetDoorState
• TargetPosition
• TargetTemperature

For example, here is how you would get the state of a switch.

$ echo $Dummy_cc5d51b840df488989b43bbadd3749c0_On
> true

The easiest way to find all available variables is to create a switch that runs the command printenv
