Introduction

This document describes the process for onboarding sites/buildings/equipment to DCH. Onboarding involves setting up continuous uploading of interval point data to DCH via MQTT to populate datastreams that can later be used for analysis by DCH applications for reporting purposes and for building controls such as demand reduction.

These instructions are generalised so as not to be hardware specific, however screenshots and examples from a Tridium Jace running Niagara 4.10 are used to help describe the process.

This procedure assumes:

1. A DCH data source has been configured by the DCH user to accept the point values as datastreams (one data stream per point). This creation and configuring of a data source is via the DCH website at https://www.dataclearinghouse.org/

2. The gateway device has been set up and is currently polling the required points from the building management system (BMS), or subsystems such as electrical management system, battery management system etc.

3. Network communications between the gateway and DCH (host: broker.dataclearinghouse.org) have been configured allowing export of MQTT messages on TCP port 8883 (for secure MQTT) which is strongly preferred, or TCP port 1883 (for unsecure MQTT) which is recommended only for commissioning communications or for low-risk data.
