Devices and methods for interacting with an HVAC controller

A method comprising:

• receiving audio that includes a predefined trigger phrase followed by a voice command to change a set point temperature of an HVAC system to a requested set point value;
• converting the audio into a natural language audio stream;
• identifying the predefined trigger phrase in the natural language audio stream;
• transmitting a part of the natural language audio stream that includes the voice command to a remote web service for identifying the voice command therein;
• when the requested set point value is within a predetermined range, receiving a first building control device command generated by and from the remote web service at a building control device, wherein the first building control device command is understandable by the building control device and instructs the building control device to change the set point temperature to the requested set point value;
• when the requested set point value is outside of the predetermined range, receiving a second building control command generated by and from the remote web service at the building control device, wherein the second building control device is understandable by the building control device and instructs the building control device to change the set point temperature to an in range set point value that is within die predetermined range;
• and
• executing the first building control device command or the second building device control command at the building control device to control the HVAC system in accordance with the first building control device command or the second building control device command.
