Will the ecobee Smart Thermostat Enhanced work with the Apple TV 4K (3rd generation) Wi-Fi + Ethernet, 128GB?
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.
