Internet of things can also be integrated with the Smart Grid, thereby enabling real-time energy optimization. Measurements, automated controls, plant optimization, health and safety management, and other functions are provided by a large number of networked sensors. The term industrial Internet of things (IIoT) is often encountered in the manufacturing industries, referring to the industrial subset of the IoT. IIoT in manufacturing could generate so much business value that it will eventually lead to the Fourth Industrial Revolution, so the so-called Industry 4.0. It is estimated that in the future, successful companies will be able to increase their revenue through Internet of things
Smart meter homes. This was well behind schedule to hit the government’s target to have 50 million in place by 2020. As of August 2018, 11 million SMETS1 devices were functioning normally, with 637,000 in "dumb" mode, according to the government. 42 million remained to be installed by the 2020 deadline. Until 2018, the vast majority of smart meters being installed were "first generation" SMETS1 types. If a user of one of these meters switches electricity supplier, the meter’s smart functions are lost, and it must be read manually. SMETS2 meters allow easy switching and better remote reading, but only 450 had
