Abstract
A method of controlling an HVAC system can include receiving audio that includes a predefined trigger phrase followed by a voice command to change a set point temperature of the 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, receiving a first building control device command generated by and from the remote web service at a building control device when the requested set point value is within a predetermined range, and receiving a second building control command generated by and from the remote web service at the building control device when the requested set point value is outside of the predetermined range.
