The Enapter Gateway is the energy site controller. It collects data from all energy devices connected via UCMs. The data is analysed and processed with user-defined commands from the Enapter Rule Engine. This logic sends commands to devices based on conditions activated by sensors or device data.
Enapter Rule Engine should be used as a convenience feature for basic non-realtime automation and not for life-sustaining or safety-critical use cases. Rules depend on working internet, Wi-Fi, and Enapter Cloud. Enapter is not responsible for any harms or losses incurred as a result of any failed automation.
