GHL Connect is a powerful, feature-rich app for ProfiLux 3, ProfiLux 4, ProfiLux Light/Mini Wifi, GHL Doser (Maxi) and Mitras LX7.

From the ground up, we built an app that allows users to easily take control of their GHL devices from the convenience of their smartphones and tablets. From its sleek modern design to its wide range of functions, GHL Connect provides a user-friendly experience across all supported GHL devices.

GHL Connect takes remote device access and control to a whole new level. Unlike other competitive solutions, GHL Connect does not rely on the Internet or external resources such as cloud services and other external servers. No Internet connection is required for a connection between the device and the app when used in a local network.
