FAQ
Common questions
Do I need a hub to start a smart home?
No. Wi-Fi smart plugs and switches work directly with Alexa, Google Home, or Apple HomeKit without a separate hub. A hub becomes useful when you add Zigbee or Z-Wave devices, which scale better past 15 devices. Start without one; add a hub when you hit that threshold.
What's the difference between Zigbee, Z-Wave, and Wi-Fi?
Wi-Fi uses your existing router (easy, no hub needed, adds router load). Zigbee and Z-Wave are low-power mesh protocols that require a hub but scale better to 20-100+ devices. Zigbee has more affordable devices; Z-Wave tends to be higher quality and pricier. Both are reliable.
What happens if my internet goes down?
Wi-Fi cloud devices and Alexa routines stop working without internet. Local hubs like Hubitat and Home Assistant keep running. Philips Hue and Lutron Caseta also process locally. If reliability matters, buy local-processing gear from the start.
What is Matter and should I care?
Matter is an open standard that lets devices from different brands work together without cloud accounts. Launched in 2022 and genuinely improving. The device catalog is still limited compared to Zigbee and Z-Wave. Buy Matter-compatible where you can, but don't let it limit your choices yet.
Are smart home devices a security risk?
They can be, particularly cheap unbranded devices from unknown manufacturers. Stick to brands with documented security practices (TP-Link, Aqara, Philips, Amazon, Samsung). Keep firmware updated. Put IoT devices on a separate VLAN if your router supports it.
How many devices do I need to get started?
Three: a hub, two smart plugs or switches, and one sensor. That's enough to build a real automation. Resist buying 20 devices at once. Start slow, learn what actually improves your day, then expand deliberately.
