Main Ecobee Smart Thermostat Models

• This is Ecobee’s flagship thermostat — their “top-of-the-line” model. ecobee.com+2ecobee.com+2
• Features include: built-in radar occupancy/motion sensor, indoor air quality (IAQ) monitoring, a smart speaker (with Alexa or Siri voice control) built into the thermostat, and support for accessories like humidifiers/dehumidifiers/ventilators.
• Comes with at least one SmartSensor (for remote room sensing), making it ideal for multi-zone homes. ecobee.com+1
• Has the largest, most responsive display and a premium build (e.g. zinc or high-quality housing).
• Because of its full set of features — IAQ, built-in voice/air-quality features, accessory support — Premium is best if you want a “do-everything” smart thermostat and want maximum comfort, convenience, and home automation integration.

Ecobee Smart Thermostat Enhanced

• The mid-tier model in Ecobee’s lineup: a balance between cost, feature set, and flexibility.
• It uses the newer radar-based occupancy sensor (so improved motion/occupancy detection compared to older models). Forbes+1
• Has a 50% larger touchscreen display compared to older/lower-end models. EnergySage+1
• Supports remote temperature control via the Ecobee app, scheduling, Eco+ energy-saving mode, and works with SmartSensors (sold separately) to manage comfort across rooms.
• Lacks some of the premium features: generally does not include built-in air quality monitor, smart speaker / voice assistant built-in, or those extra sensors/accessory integration out of the box.
• It’s a strong choice if you want many smart-thermostat features at a lower price than Premium and don’t necessarily need built-in IAQ monitoring or a speaker.

Ecobee 3 Lite Smart Thermostat

• The entry-level, budget-friendly smart thermostat from Ecobee — a simpler, more affordable option.
• Provides core smart thermostat functions: Wi-Fi connectivity, remote control via app, scheduling, basic automation, and compatibility with remote SmartSensors (if you buy them separately).
• However, it does not include built-in occupancy or motion sensors, IAQ monitor, smart speaker, or some premium hardware features — those need add-ons (e.g. external SmartSensors). SafeWise+2Manuals++2
• Because of its simplicity and lower cost, 3 Lite is a good fit for small apartments or homes, or for users who just want basic “smart thermostat + remote control + scheduling” without paying for advanced features.

Comparison: Which Model Should You Choose?

Real-world Scenarios & Who Each Model Is Best For
