3. Apple HomeKit

From lights and bulbs to locks, motion sensors, room quality monitors, outlets, switches, and thermostats, Apple HomeKit is proving to be another large superstore for IoT products – for Apple users, of course.

Other Honorable Mentions

The smart homes product space is very competitive. Samsung has divested its stake in the SmartThings platform, and some of its products, such as SmartThings Hub v3, is now carried by a company called Aeotec.

Very few smart home companies have grown to the revenue size of the top few. That doesn’t mean they are insignificant. They are growing either as a subsidiary of a very large company or are merging into the ecosystem of a more thriving unit. These are the companies you need to watch for.

  • Siemens, Honeywell, GE, LG, and Sony
  • Sengled, eero, Lutron, Advantech


Smart home consolidation is going to be an inevitable outcome of many IoT companies as they start growing in scale. Already there are mergers and acquisitions ongoing in this space with Apple, Amazon, Google, Bosch, and other behemoths acquiring innovative startups.
