Smart Thermostat reference demo is based on Kinetis family MCU (K70F120M) and KW24D512 zigBee coordinator. The demo kit has an HVAC application which controls the heat/cool temperature, hvac mode etc of the remote temperature sensor via zigBee coordinator. The demo kit Connects to WAN via Ethernet or wifi. The wifi module used is a wifi module from Qualcomm.  The embedded DeviceCloud cloud agent provides firewall agnostic instant cloud connectivity. The device can be registered and authenticated with DCIO cloud platform and the remote temperature sensor can be monitored and controlled through DCIO Mobile Application.


The K70 application is built for MQX RTOS v4.0.2 and uses our PEG graphics library for the user interface displayed on an LCD. The K24 application is built on MQX-Lite RTOS, uses our BeeStack ZigBee stack. The demo will also connect with an off-the-shelf ZigBee light bulb and wirelessly controls it.


The reference design provides guidelines for building solutions using connected devices that can be managed, provisioned and monitored from Cloud and Mobile applications.
