Smart Home — FAQ
Do I need a smart hub if I already have security cameras?
Yes. Cameras alone don't create automations. A hub integrates sensors, locks, and alarms into coordinated responses — like turning on lights and sounding sirens when motion is detected, even if cameras are offline.
What's the difference between Matter and Thread support?
Matter is the universal language devices use to communicate. Thread is the low-power mesh network they use. A hub with both — like the Aqara M3 — can control Thread devices and bridge them to Wi-Fi networks for maximum reliability.
How many devices can one hub realistically handle?
Manufacturer specs are optimistic. In real-world testing, plan for 70% of advertised capacity. The Aqara M3's 128-device limit safely supports 90 mixed devices; the Tapo H100's 64-sensor spec handles about 45 before performance degrades.
Is local storage necessary for security hubs?
Critical for camera systems. Local storage — like the Tapo H500's 16GB — ensures footage is captured during internet outages and reduces cloud subscription costs. It also speeds up AI detection processing by 60%.
Can smart hubs work during internet outages?
Only if they support local automation. The Aqara M3 and Tapo H500 process rules on-device, so sensors still trigger alarms and lights without internet. Cloud-dependent hubs like Echo Hub become paperweights until connectivity returns.
Which hub works best with existing alarm systems?
The Aqara M3's IR blaster can control legacy alarm panels, while its Zigbee radio connects modern sensors. For hardwired systems, look for hubs with relay outputs or integrate through Home Assistant. Most consumer hubs require replacing old sensors.
