Smart Home Hubs, Controllers and Starter Kits

Does your gear need a hub at all?

Wi-Fi devices talk straight to your router, so a hub earns its place only when devices use another radio. Zigbee hubs run Zigbee 3.0 gear, Z-Wave hubs run Z-Wave gear, and Bluetooth gateways bridge short-range sensors to the network. Z-Wave radios are tuned to regional frequencies, so a 900 MHz hub must match the devices' region. Many hubs also work with a voice assistant and an app; confirm which, because that decides how automations are created.

Maker kits, relay modules and voice controllers

The category mixes consumer products with hobby parts. A voice controller or smart display needs only power and an app. A Wi-Fi relay module or a Raspberry Pi Pico sensor kit is a build-it-yourself item: it arrives as parts, needs wiring and code, and has no finished app. Relay modules that switch mains power should be installed by a qualified person, while 5 V USB-powered kits are safer for learning. Check the box contents, such as remotes, cables and power adapters, to see what you still need.

Questions about Smart Home Hubs, Controllers and Starter Kits

Is a Zigbee hub the same as a Z-Wave hub?

No. They use different radios and protocols, so devices of one type do not work with a hub of the other. Some multi-protocol hubs include both radios; check the listing for the protocols named.

Can a smart speaker act as the hub?

Some speakers and displays contain Zigbee or Thread radios and can control compatible devices directly, while others only relay voice commands to Wi-Fi devices. The product specifications list the protocols it supports.

Do DIY relay and sensor kits work out of the box?

Not as finished products. They usually need wiring, a power supply and firmware or code, and the maker's app may not exist. Beginners should use low-voltage kits and avoid switching mains power without help.
