Check your own equipment before you buy.

What separates ecobee Premium from Enhanced?

Premium includes more built-in features, while Enhanced focuses on smart temperature control. Both can adjust temperature based on occupancy, and both can work with added SmartSensors for room-by-room comfort.

Premium's included SmartSensor detects which rooms are in use. It also has a built-in air quality monitor, a radar-based occupancy sensor and a speaker with Siri or Alexa built in.

Enhanced has occupancy sensing, schedule learning, app control and humidity adjustments. Its SmartSensors are sold separately, so include that extra step if you want to prioritize comfort in rooms beyond the thermostat's location.

What does the Premium add over Enhanced?

Premium adds an included SmartSensor, air quality alerts and a built-in speaker. It can also remind you to change your furnace filter and offer tips when air quality drops.

Premium can stream a live view from an ecobee Smart Doorbell Camera and support two-way talk from the thermostat. That feature requires the camera, and smoke alarm sound detection requires an ecobee Smart Security subscription.

Its speaker supports Siri or Alexa. Siri requires an Apple home hub, so check your existing smart home setup if voice control is a deciding feature.

For more detail on its features and tradeoffs, read our ecobee smart thermostat Premium review. If you choose Premium, our guide on how to use ecobee Smart Thermostat Premium explains its controls and settings.

What does Enhanced still do well?

Enhanced provides smart control without the Premium's built-in air quality monitor or speaker. It can adjust temperature when you're away or asleep, learn your schedule and preferences, and adjust for humidity.

You can control it through the ecobee app, including from a smartphone, tablet or Apple Watch. It works with Amazon Alexa, Google Assistant, Apple HomeKit and SmartThings.

Adding ecobee SmartSensors lets you detect occupied rooms and help prioritize comfort there. If you want the full model-specific breakdown, see our ecobee Smart Thermostat Enhanced reviews.

Which model is better for room-by-room comfort?

Premium is the simpler pick if you want a room sensor included; either model can support added SmartSensors. The sensor helps the thermostat respond to room use rather than relying only on the reading near the thermostat.

A sensor can matter when the hallway temperature doesn't reflect the bedroom or living room where you spend time. Consider where you want to prioritize comfort and whether you want to add sensors over time.

Premium comes with one SmartSensor. Enhanced's SmartSensors are sold separately, giving you the option to add them as needed.

Room sensors don't remove the need to check your heating and cooling setup. For other options in the brand's lineup, see our guide to the best ecobee smart thermostat.

Which thermostat has broader HVAC compatibility?

The stated compatibility figure is higher for Premium, but neither percentage guarantees it will work with your system. ecobee describes Premium as compatible with 95% of HVAC systems and Enhanced with 90%.

Those figures are a starting point, not a substitute for checking your system's wiring and equipment type. Use ecobee's thermostat compatibility checker to confirm before buying.

Smart thermostats can have limits across system types, wiring and voltage. Our guide to what HVAC systems work with smart thermostats explains what to check before choosing a model.

Both Premium and Enhanced include a Power Extender Kit for homes without a C-wire. That doesn't mean every home without a C-wire can use either thermostat; confirm your system type and follow ecobee's installation guidance.

The WUKUR Power Extender Kit is described for compatible ecobee thermostats on 24 VAC systems without a C-wire. Its compatibility notes exclude dual transformer, fan coil, communicating, millivolt and high-voltage systems, so verify the setup before considering it.

Should you choose Premium for humidity or air quality?

Choose Premium if you want a built-in air quality monitor; Enhanced adjusts for humidity but has no built-in air quality monitor stated here. Those are different functions, so decide which information or adjustment matters to your home.

Premium can alert you when air quality drops, offer tips and remind you to change your furnace filter. Enhanced's stated humidity adjustment helps keep the home comfortable, but it doesn't replace separate air quality monitoring.

A thermostat's humidity feature is not a dehumidifier. If humidity control is a priority, learn how a smart thermostat controls humidity and check what your HVAC equipment can do.

Which is easier to set up?

Both models include a Power Extender Kit and trim plate for installation, including homes without a C-wire where the system is compatible. Check the wiring and system requirements before removing your existing thermostat.

The Premium package includes a SmartSensor, backplate, wire labels, screws and drywall plugs, a power extender kit, trim plate and quick start guide. Enhanced also includes the backplate, wire labels, screws and drywall plugs, power extender kit, trim plate and quick start guide.

If your current thermostat leaves a visible hole or mark, the CaseBot wall plate is made for the 2022 Premium and Enhanced models. It measures 6.14 x 6.14 inches, has a matte black finish and comes with screw sets; the thermostat is not included.

Measure the wall area and check your exact thermostat model before choosing a plate. CaseBot says it will not fit other ecobee thermostat models.

For general setup planning, review the wiring and HVAC compatibility details before buying. Don't assume that a trim plate or power extender kit makes an otherwise incompatible system suitable.

What are the practical tradeoffs?

Premium makes sense when you want its included sensor and built-in extras; Enhanced makes sense when its core controls cover your needs. Both support app control and offer occupancy-based adjustments.

Premium is the more feature-rich option on the details compared here. Its built-in speaker and air quality monitor may be useful if you want those functions at the thermostat rather than through separate devices.

Enhanced leaves the room sensor as an add-on and does not include the stated air quality monitor or smart speaker. In return, it still offers schedule learning, occupancy sensing, humidity adjustments and broad smart home compatibility.

Think about what you'd use week to week. If you mainly want to adjust schedules remotely and have the temperature respond to occupancy, Enhanced covers those needs; if you also want air alerts, voice features and an included sensor, Premium has the stronger feature set.

Is ecobee Premium or Enhanced the better choice?

Pick Premium if you want the included SmartSensor, built-in air quality monitor and speaker; pick Enhanced if you want smart temperature control and can add room sensors separately. Confirm HVAC compatibility and wiring before deciding.

Premium's higher stated compatibility percentage may be a useful starting point, but it isn't proof that your exact system will work. Check the model with ecobee's compatibility tool, then weigh the built-in features against the add-ons you'd need.

The ecobee Smart Thermostat Premium vs Enhanced decision is straightforward when you start with your must-have features. Choose Premium for its included extras, or Enhanced for occupancy-aware control with optional sensors.

For an alternative from another brand, compare the Google Nest Thermostat review. If you're choosing for a recreational vehicle, check whether a smart thermostat for an RV fits the vehicle's system before buying.
