Ecobee SmartThermostat Premium Review: 2025 Update

Overview

The Ecobee SmartThermostat Premium remains one of the most complete smart thermostat packages on the market in 2025 because it solves a very common problem better than many rivals: the fact that homes do not heat and cool evenly. The thermostat on your hallway wall might think the house is comfortable while the nursery is roasting and the bedroom is freezing.

Ecobee's answer is remote room sensors, and it is still a compelling one. Add in a polished app, built-in voice assistant support, strong scheduling, and an attractive glass-fronted design, and you have a thermostat that feels genuinely smart rather than merely connected.

Design & Hardware

The Premium model looks the part. The large touchscreen is clear, the glass front feels upscale, and the overall hardware is more polished than many utilitarian thermostats. It is the kind of device that does not embarrass itself on the wall.

Installation is typical for a smart thermostat, which means “easy if you are replacing a conventional thermostat and your wiring is sensible, slightly nerve-wracking if your HVAC setup is mysterious.” Ecobee includes a Power Extender Kit for homes without a C-wire, which broadens compatibility and reduces one of the common barriers to entry.

Remote Sensors

The remote sensors are still the reason to buy Ecobee. You can place them in bedrooms, offices, or living areas and have the system average temperatures or prioritise occupied rooms. This makes a real difference in homes where one room gets much hotter than the rest in summer or much colder in winter.

It also improves comfort in a way people notice immediately. Smart thermostats often get sold on energy savings alone, but comfort is what keeps people happy. Ecobee understands that. If you work from a back office all day, it is nice not to have your comfort dictated by the temperature in the corridor.

Smart Features

The SmartThermostat Premium supports smart scheduling, occupancy detection, geofencing, humidity monitoring, and voice control. It plays nicely with Alexa, Apple Home, and Google Assistant ecosystems, and it has broader smart home credibility than many thermostat brands because Ecobee has been at this for years.

Its eco features are also useful rather than patronising. Usage reports and eco suggestions can help reduce heating and cooling waste, especially if you are upgrading from a basic thermostat that offered no insight at all. The thermostat can adapt around your routines instead of simply blasting the HVAC on a rigid timer.

App Experience

The Ecobee app remains one of the better thermostat apps available. Schedules are easy to edit, sensor data is visible, and switching between Home, Away, and Sleep-style comfort settings is intuitive. Compared with cheaper thermostat apps, this feels thought through.

That said, some buyers may feel the Premium model is more thermostat than they need. If your home is small and evenly heated, the full Ecobee experience may be overkill. But in larger homes, multi-storey layouts, or households that actually care about fine comfort tuning, the benefits are clear.

Verdict

The Ecobee SmartThermostat Premium is still one of the best smart thermostat choices in 2025, especially for homes with temperature imbalances. Remote sensors remain its killer feature, and the app, hardware, and ecosystem support all feel mature.
