Configure or reconfigure your nLight AIR lighting control system from Acuity on your mobile phone or tablet. The Clairity mobile app from Acuity Controls, allows end users (electrical contractors, sales agents, or facility maintenance professionals) to startup, configure, troubleshoot, and reconfigure nLight AIR wirelessly from a smart phone or tablet. The Clairity app is optimized for efficient onsite startup and maintenance activities. It allows end-users to easily modify the settings and operation of the fixtures, sensors, and wall switches in a zone, aiding in meeting energy code requirements. For larger installations, multiple users may use the Clairity mobile-application simultaneously to reduce onsite time. Leave the ladder and laptop in the truck! Using Bluetooth™ Low Energy (BLE) communications, users configure zones of fixtures and wall switches without the need for special hardware adaptors or wires. Utilizing a simple, visual interface, that provides real-time feedback, configure the equipment to work together for a consistent look or allow each fixture to operate independently. No Wi-Fi? No cellular service? No problem. We know the wireless and cellular coverage can be spotty in commercial buildings. You can make programming adjustments even with Clairity completely offline. Once your mobile device senses a connection to the internet, all of the configuration parameters will be backed up in the cloud!
