BWCADAPTER 1 INTRODUCTION 1.1 Purpose This document describes the Bradford White’ BWCADAPTER commercial and residential IoT Gateway. Targeted for controlling water heaters and boilers placed in Buildings and Industries. Core features are its Hardware Design with Radio Connectivity such as Wi-Fi and BLE. Apart from the radio connectivity options, the BWCADAPTER is also capable of standard industrial interfaces like micro SATA, RS-485, and MODBUS.
BWCADAPTER 2 PRODUCT OVERVIEW Figure 1 BWCADAPTER Figure 2 BWCADAPTER PCBA Rev 3.0.
BWCADAPTER The BWCADAPTER system is a smart home/commercial system that will enable residential and commercial water heaters and boilers to be smart, which means the user can control the heater, monitor the energy consumption, and receive alerts whenever the heater runs into any flaw, specifications are as follows, • • • • • • • • • GEA2 and Modbus RTU connectivity to Water heater/boilers Wi-Fi connectivity to the Ayla cloud BLE connectivity for provisioning and local debugging/maintenance Robust, reliable
