  • EphesusAIRMESH HUBpartial

    Ideal for facilities that may not have access to the outside world via internet connection, the AirMesh Hub is a key component of the entire LED lighting system. It can switch lights off or on, or dim them to a specified level. Zones can be established so that lights in a particular area can be controlled separately from others. The system stores power data, behaviors, alarms and critical events locally for maintenance and troubleshooting.
