Pros and cons

Drawn from the published specifications and what else you have to buy. Not a lab score.

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.
