Minimum HW/OS requirement for Android Companion App

What minimum requirements should I go for in a tablet to be used for wall mounted dashboard via Fully Kiosk Browser AND the Android Companion App?

Best regards

the minimum version that the android app supports is 5…depending on what you want to accomplish though you may want to strive for 8 or higher. The companion docs will detail which features require a specific version if not supported in version 5. For example android power menu feature is only available in android 11.
