Buying advice: smart home

Pick devices compatible with the assistant you use. Matter support makes devices work across platforms.
Wi-Fi devices are simple but add load to your router. Thread and Zigbee devices need a hub but are more responsive and battery-friendly.
Devices that work locally keep running when the internet drops.
Review microphone and camera settings and use two-factor sign-in on accounts.
Smart devices depend on company servers and updates. Established brands are less likely to drop support.

Do smart lights need a hub to work?

It depends on the brand. Philips Hue requires a Hue Bridge hub (included in starter kits) for full functionality, without the hub, bulbs are uncontrollable if Wi-Fi goes down and cannot be automated. LIFX bulbs connect directly to Wi-Fi, no hub needed. Kasa bulbs (TP-Link) connect directly to Wi-Fi with no hub. Zigbee-based bulbs (most Hue, IKEA Tradfri) need a Zigbee hub or a smart home controller with Zigbee (Amazon Echo 4th Gen, SmartThings). Wi-Fi bulbs are simpler to set up but add to Wi-Fi network congestion. Zigbee bulbs are more reliable and responsive but require the hub investment.

Are smart bulbs compatible with all light fixtures?

Smart bulbs replace standard A19 (medium screw) bulbs in any fixture that accepts that base. They will not work in enclosed, airtight fixtures (sealed flush mounts), the heat buildup exceeds the rated temperature and dramatically shortens bulb lifespan. Most smart bulbs specify 'not for use in enclosed fixtures' in the specifications. For recessed cans: smart bulbs work if the can is open on the bottom (most are). For ceiling fan light kits: check that the socket is a standard A19 base, some fan kits use smaller candelabra (E12) bases that require a smaller smart bulb.
