Edge iO 28 Controller

Tech Specs
Feature Spotlight

The Edge iO 28 is Nube iO’s IoT and BMS building controller. This device provides a low-cost control solution for small to medium sized buildings. We’ve taken the best parts of legacy devices and condensed them into one low-cost, IoT ready controller.

This building controller serves a number of purposes. Firstly, this device aggregates all building data from assets and field devices. Secondly, it controls building sub-systems. Thirdly, it sends and receives data from the cloud.

Standalone building management system (BMS)
Extract data from an existing BMS
Control HVAC, lighting and other sub-systems and assets
Push data to 3rd party cloud services
Create schedules, alarms and alerts for given parameters
