Enerallies IOT SaaS Platform

About EnerAllies

EnerAllies provides solutions to reduce HVAC energy and maintenance costs for small-format retail and restaurant chains without a heavy investment of money or time. The company is transforming energy management from a hardware-heavy industrial controls approach to a software-centric and data services solution.

Their solution reduces energy costs, reduces repair cost with an early warning system, provides a premium customer experience by improving site comfort and saves time with the remote management and data-insight services. Their software-based approach eliminates having to pay for, manage and support complex HVAC control hardware.

The Challenge

The web-based energy management portal on the AWS Cloud is built for multi-site enterprises, providing centralized control and access to a range of energy cost, usage and operational information, alarms, diagnostics, and analytics.

The product has a high data velocity and volume; which the energy management platform manages using the AWS IOT platform. However, it was essential for the business to quickly on-board the enterprises and their IoT devices to collect data and automatically manage them.

CT Solution

CT approached the challenge by EnerAllies IOT platform as a AWS cloud based SaaS . On boarded enterprises (Tenants) used shared resources to minimize cost with client isolation achieved thru client context injection across all the layers.

With each device getting registered on AWS IOT platform, their state is being recorded. Data is transferred to rules engines and from there to Kinesis. Kinesis Analytics filters, transforms, aggregates the data with standard SQL and sends back processed data. This provides them with live streaming dashboard to get unified experience of all connected devices.

Data is stored in AWS Aurora, in multi-tenant tables that were partitioned by tenant for data separation.
