Understanding the MobiusFlow® balenaCloud Device Variables
balenaCloud devices are configured using Device Variables. When deploying MobiusFlow® to a balenaCloud fleet a number of Device Variables are created with default values. These are defined at the fleet level but can be overridden at the device level. More information about working with balenaCloud Device Variables can be found here.
For most devices the only Device Variables that require changing are listed below. The rest can be left at their default values.
MOBIUS_LICENCE
MOBIUS_HUB_ID
Remember to override the Device Variables at the device level and not at the fleet level.
Any changes at the fleet level will apply to all devices in the fleet.
