NEW YORK, Dec. 1, 2016 /PRNewswire/ -- The global smart thermostat market is expected to reach USD 2.99 billion by 2022, according to a new study conducted by Grand View Research, Inc. These thermostats enable users to remotely control their air conditioning as well as heating systems through wireless connectivity and mobile apps. Smart thermostats form an integral part of smart homes and have gained high traction in developed regions such as Europe and North America. The industry is anticipated to witness a high adoption of these gadgets as they display the energy consumption level in real-time and are capable of adjusting to ambient conditions automatically. These devices can be connected to the internet and offer analytics and performance measurement tools through web-based portals. They are usually an integral part of the home automation ecosystem. Energy utility retailers play a vital role in promoting the adoption of these devices in households. Many utilities offer these products as a part of their home energy management schemes. The involvement of energy retailers amplifies the potential for the smart thermostat industry growth. Additionally, the proliferation of mobile phones and their convergence with thermostats make these products much more attractive for the end-users.The growing penetration of smartphones, rising per unit energy costs, the need for effective energy management solutions, and the favorable regulatory scenario are expected to propel the market growth over the coming years. The increased penetration of Near Field Communication (NFC) and ZigBee home automation devices is further expected to augment the demand. However, the high cost of devices and the associated data security concerns may restrain the growth prospects of this industry.
