FAQ
Do I need a hub for smart home devices?
Not always. Wi-Fi devices like Kasa plugs and Wyze cameras work without a hub. But Zigbee and Z-Wave devices need a hub (SmartThings, Echo Plus, or dedicated hub).
What is Matter and do I need it?
Matter is a new smart home standard that lets devices work across Alexa, Google, and Apple. Devices marked “Matter-compatible” can work with any Matter controller. It launched in late 2022, so not all devices support it yet.
Can smart home devices work without internet?
Some can. Philips Hue works locally after setup. SmartThings and HomeKit support local automations. But voice control via Alexa/Google requires internet.
Which ecosystem is most open: Alexa, Google, or HomeKit?
Alexa has the most compatible devices. Google Assistant is close behind. HomeKit is more selective (requires Apple certification) but more privacy-focused.
How many devices can one hub control?
SmartThings Hub: 232 devices per hub. Philips Hue Bridge: 50 lights. Echo devices with Zigbee: varies by model but typically 50-100 devices.
Common Pitfalls
- Mixing ecosystems without checking compatibility
- Assuming all “smart” devices work together
- Not checking if subscription is required for features you want
- Buying discontinued products (check manufacturer website)
- Forgetting to check Wi-Fi requirements (2.4GHz vs 5GHz)
