A report out from the US today estimates that by the year 2020 Smart Home devices such as Amazons Alexa, Googles Home, Apple Homepod, Sonos and Philips Hue will hit sales figures of 55 million units.  This is in the USA, I'd expect Thailand to be significantly behind this but it's a pointer of the way things are going to go as Smart Phones and Smart Homes become more ubiquitous.

"U.S. households with existing broadband service will purchase nearly 55 million smart home devices in 2020 if current trends continue, according to a report from Parks Associates.

The report found that although many smart home devices are still in the early adoption stage, the number of U.S. households installing smart thermostats, lights, locks, or networked cameras climbed from 12 percent earlier in the year to 15 percent.

A previous report said that connected appliances, thermostats, and home security systems were the most popular applications.

"Collectively, U.S. adoption of smart home products is nearing the threshold of the early majority, thanks to marketing efforts of large players, popularity of voice-based products, lower product costs, and a focus on the consumer experience in the purchase process," said Senior Vice President Elizabeth Parks. "And consumers are beginning to recognize the value propositions of platforms such as smart video door bells and smart thermostats, which is boosting their adoption both for household use and as gifts."

The report also found that 42 percent of home security systems included a smart home device such as an electronic lock, smart thermostat, or smart light as of Sept. 11.

Although the ability to remotely monitor doors is convenient, setting up those systems can be onerous and consumers appear to remain concerned about the potential weaknesses of smart devices. A recent survey by NPR and Edison Research indicated that a majority of respondents who did not own a smart speaker were concerned about cost or lacked information about what smart speakers do."
