This number of IoT endpoints is considerably lower than the 19 billion autonomous IoT clients that the market researcher estimated back in 2013 (Gartner puts a number on IoT in 2020). Now Gartner estimates that there will be 4.8 billion automotive and enterprise endpoints in 2019 that will be up 21.5 percent on the number in 2018.
The biggest demand for IoT endpoints will come from utilities, totalling 1.17 billion endpoints in 2019, and increasing 17 percent to reach 1.37 billion endpoints, in 2020. "Electricity smart metering, both residential and commercial will boost the adoption of IoT among utilities,” said Peter Middleton, senior research director at Gartner, in a statement. "Physical security, where building intruder detection and indoor surveillance use cases will drive volume, will be the second largest user of IoT endpoints in 2020."
Building automation, driven by connected lighting devices, will be the segment with the largest growth rate in 2020 (42 percent), followed by automotive and healthcare, which are forecast to grow 31 and 29 percent in 2020, respectively. In healthcare, chronic condition monitoring will drive the most IoT endpoints, while in automotive, cars with embedded IoT connectivity will be supplemented by a range of add-on devices to accomplish specific tasks, such as fleet management.

Similar to 2019, residential electricity smart metering, which can be used for more accurate metering and billing in the home, will be the top use case for Greater China and Western Europe in 2020, and will represent 26 percent and 12 percent of total IoT endpoints, respectively. North America, in comparison, will see its highest IoT endpoint adoption in building intruder detection, such as door and window sensors, which will represent 8 percent of total IoT endpoints.
