KOLO™ Connect is the app used on-site by installation vendors, maintenance contacts and GP PRO’s customers to set up the KOLO™ Smart Monitoring System. Via the proprietary cloud-based IoT KOLO™ platform, KOLO™ Connect makes it possible to survey and set up a site, commission and replace dispensers and verify connectivity of the KOLO™ Smart Monitoring System. The System joins advanced sensor and communication technology with the industry-leading dependability of enMotion® paper towel, soap and sanitizer dispensers and Compact® toilet paper dispensers. The technology assesses when products are low or out, when paper is jammed or when batteries need replacing, and communicates that information via alerts and status reports to custodians and facility managers. KOLO™ Connect allows installation and maintenance vendors to: • Enter all KOLO™ enabled dispensers and collectors that will be commissioned into the System during the site survey/set-up process • Verify connectivity after all dispensers and collectors are commissioned KOLO™ Connect allows customers and GP PRO Deployment Managers to: • Commission collector devices and KOLO™ enabled dispensers • Commission replacement dispensers
