HVAC contractors across the United States are working with a select group of homeowners looking to use their mobile devices to remotely control their indoor environment. A few are also partnering with Home Automation dealers to use Wi-Fi thermostats as a complement to high-tech lighting, security, and audio/visual systems for high-end homes. It is a niche market now but that should change significantly in the next two years as consumers with smart phones and tablets become aware of the remote control capability of HVAC thermostats and systems. That pace of change will also be affected as traditional contractors realize home connectivity is more than a gadget or one more thing that could go wrong.
