Gen-Sentinel is a monitoring device for permanently installed backup electricity generators. It watches for problems on a continuous 24/7 basis. It’s like having a service technician standing by the generator at all times, watching for trouble. When it sees something wrong, it notifies the customer and his service provider immediately. It is a digital cellular device that hooks up to the generator via a 4-wire connection. This app gives you access to your generator records and allows you to configure your account.
