Recap

There are several smart home protocols to choose from, but the most popular ones have a lot in common. Whether you choose a Zigbee-, Z-Wave-, Insteon-, Bluetooth-, or Thread-based smart home ecosystem depends largely on which devices you want to use and which features are most important to you.

If you already have smart home devices, or a home security system, check to see which protocols they work with and what other devices you could add.
