The ecobee4 is a powerful smart thermostat that can be controlled via its display, voice control, or mobile app. It's able to use room sensors that measure both temperature and occupancy to optimize HVAC settings, whether you're home or not. It helps save energy and is hardwired.


This thermostat comes with a wide range of powerful features. The wireless room sensors, voice control, and smart alerts are highly useful. Home IQ shows how much energy has been conserved each month, giving valuable insight into heating and cooling equipment. It’s almost like a home energy.

Be sure to check compatability with your own HVAC system before making any purchase.


The ecobee4 is designed for 24VAC with a 2A maximum current. Do not connect it to line (high) voltage or millivolt systems. It works to monitor HVAC equipment performance and send alerts if anything isn't working properly. It also provides service reminders to help you maintain your equipment.

Like any other thermostats, this should be located on an inside wall, about five feet up from the floor and must be protected from any liquids or excessive moisture. If you need help installing the thermostat, contact a professional.


Overall, the ecobee4 Smart thermostat is one of the most powerful (and best looking) smart thermostats available. Packed with advanced features, owners will be able to customize indoor environments, save energy, and control settings remotely. It's certainly more expensive than most other smart thermostats, but its performance is hard to beat.
