At the heart of the 75Fahrenheit system are its Smart Algorithms and Progress® Kinvey™. Wireless zone controllers and air supply sensors continuously collect building and system parameters and send them to the Central Control Unit (CCU)—an Android mobile device and application. The CCU aggregates this minute-tominute time series information and pushes it to the Kinvey serverless backend data store for processing.Using APIs, the Kinvey data store pushes this data to a Node.js application running on-site in 75F’s data center that processes all these inputs and creates the optimal control strategy. The optimal control strategy is sent back to the CCU, which then proactively commands the smart dampers to the required positions and turns on the HVAC equipment during the day.
With Kinvey, 75Fahrenheit didn’t have to worry about having in-house expertise in a wide range of areas like database management, custom web service APIs, user management, offline/online sync and messaging.“While all of these are critical for our system as a whole, they are not core to our temperature control application logic,” said Deepinder Singh, CEO of 75Fahrenheit. “By leveraging Kinvey’s ready-to-use frontend and backend services, as well as an extremely responsive team that resolves issues within hours, we were freed from having to use our resources to build in-house expertise in these areas.”
