Compatibility answer

Will the ecobee Smart Thermostat Premium work with the Apple TV 4K (2nd generation)?

Yes, with conditions. Works, but it also needs Thermostat C-wire (24VAC common wire).

Both records are reviewed against the manufacturers' sources; sources last checked 2026-10-14. Informational only: confirm with the manufacturer before buying.

Why

  • ✓ Both use Apple Home (HomeKit).

Conditions

  • Thermostat C-wire (24VAC common wire): Needs another device that provides Thermostat C-wire (24VAC common wire).

Good to know

  • Remote control and automations require an Apple home hub (HomePod mini, HomePod, or Apple TV).
  • Thread-enabled Matter accessories require a Thread-enabled home hub such as HomePod mini or Apple TV 4K (3rd generation) Wi-Fi + Ethernet.
  • It also relies on Thermostat C-wire (24VAC common wire), which this device doesn't provide. You may need another device in the home that does.
