Description

Creating a low-power, connected, microcontroller (MCU) based smart thermostat that can securely link a variety of sensors to the cloud, which enables remote monitoring and control, is the goal of most smart thermostat designers. The TIDM-1020 reference design provides a software reference for the implementation of such a smart thermostat, using the CC3220 device as the primary MCU, with Wi-Fi® connectivity. This application note provides the details of adding Bluetooth Low Energy (BLE) connectivity for provisioning to TIDM-1020.

This reference design is for thermostat end equipment developers, engineers, and system evaluators. The design provides reference code to demonstrate integration of the CC3220SF device into a variety of analog and digital sensors, cloud connectivity services, human machine interfaces (HMIs), passive infrared (PIR) sensors, and external relay controls. This reference design is also intended to showcase: low-power connection to the Internet and cloud, remote control and programming, remote monitoring of the data, and secure Over The Air (OTA) update of the device and application firmware.

Features
  • Demonstrates battery life of ~6 months using 2AA batteries
  • HMI through resistive touchscreen
  • Cloud connectivity for remote control and sensor data aggregation and monitoring
  • Demonstrate the security features
    • Secure OTA update
    • Secure server
    • Internal HTTPS server
    • Secure sockts (SSL/TLS)
  • Provisioning (BLE based, Access Point (AP) Mode and SmartConfig™)
  • Low power capabilities
  • Configurable sensor update rate
