Site-Specific Theming

Site-Specific Theming is a Launcher feature that enables the usage of different Launcher themes based on the device location.


Site-specific theming is a Launcher feature that customizes the appearance of the device UI by adding a logo, choosing background colors, and setting an accent color specific to one store or site. With this feature, organizations can customize the appearance of their device's screen to match their needs and preferences. It provides a tailored visual experience depending on where the device is being used.

User Guide

The Site-Specific Theming feature can be enabled or disabled within the Launcher configuration. If the "theme" parameter "enable" is set to true (the default value), the device will enable theme support, including the option of setting "altThemes" objects for different sites.

The Launcher will determine which if any of the alternative theme objects match up to the siteTheme column on the device's sitelist.csv file. If no alternative themes match, the Launcher will default to the primary "theme" object.
