Aqara
Hub M3
Confirm the current Aqara price for your region. PoE and USB power are both on the spec sheet.
Pros
- • PoE or USB power, plus Ethernet-class reliability if you use the PoE input.
- • One box is a Zigbee hub, Thread border router, and Matter controller.
- • Listed for Apple, Alexa, Google, and SmartThings, so it is not locked to one phone brand.
Cons
- • You still set it up in the Aqara app.
- • Advanced Aqara features are not the same thing as the Matter entities other apps see.
- • It is a hub only. It does not route the home’s Wi-Fi.
Nabu Casa
Home Assistant Green
See the current price on home-assistant.io. A Thread/Zigbee radio is a second purchase.
Pros
- • Local control without a phone-brand account in the middle of every automation.
- • Low published power draw and a Gigabit port.
- • Matter over Wi-Fi does not require the extra radio. Thread does.
Cons
- • No built-in Thread or Zigbee. Budget Connect ZBT-2 or an existing border router.
- • No built-in Wi-Fi. It wants an Ethernet drop.
- • You maintain updates, backups, and integrations yourself.
