Our Review

Ecobee3 Lite Pro Smart Thermostat Review


The Ecobee3 Lite Pro Smart Thermostat emerges as a solution for those seeking to enhance their home's intelligence without breaking the bank. This device positions itself as a more affordable alternative to the original Ecobee3, yet it still offers a suite of robust features designed to integrate seamlessly into the modern smart home ecosystem. This review delves into the capabilities of the Ecobee3 Lite Pro and its relevance to homeowners who prioritize convenience, energy efficiency, and smart home connectivity.

Design and Build


The Ecobee3 Lite Pro boasts a sleek, minimalist design that complements a contemporary home interior. The 3.5-inch color touchscreen serves as the focal point, offering easy temperature adjustments and a clear display of settings. However, the use of color on the display is limited, which could detract from an otherwise premium-looking interface.

Build Quality

Constructed with durability in mind, the Ecobee3 Lite Pro exudes quality. The materials used convey a sense of reliability, and the touchscreen responds well to touch, suggesting longevity in everyday use.

Installation Process

Installation is straightforward for those with a C wire already in place. The inclusion of an adapter is a thoughtful touch, catering to homes without a C wire. While most users find the installation process to be a breeze, some have reported issues with the adapter, which could lead to complications for the less technically inclined.


Smart Home Integration

One of the thermostat's strongest selling points is its broad compatibility with smart home systems. Whether you're entrenched in the Amazon Echo, Google Home, Apple HomeKit, or other ecosystems, the Ecobee3 Lite Pro integrates smoothly, allowing for a centralized and harmonious smart home experience.

Remote Access and Control

Remote control via smartphone is a feature that has become almost expected in smart thermostats. The Ecobee3 Lite Pro doesn't disappoint, offering users the ability to adjust temperatures and settings from anywhere, provided they have an internet connection.

Motion Sensor and Activation

The motion sensor for automatic activation is a welcome feature, adding a layer of convenience and energy efficiency. This sensor allows the thermostat to adjust settings based on the presence of people in the room, potentially saving energy when no one is home.

Energy Saving Aspects

The Ecobee3 Lite Pro offers detailed energy usage reports and system efficiency insights, which are invaluable tools for those looking to reduce their carbon footprint and save on energy bills. The potential savings could offset the initial investment in the thermostat over time.


Temperature Monitoring and Control

The Ecobee3 Lite Pro's core function—temperature control—is executed with precision. Users can expect consistent and accurate temperature regulation, which is the cornerstone of any quality thermostat.

Multi-Room Monitoring

While the Ecobee3 Lite Pro supports multi-room temperature monitoring, the necessary remote sensors are sold separately. This is an important consideration for those with larger homes, as the additional cost can add up.

User Interface and App Experience

The user-friendly app and responsive touchscreen are highlights in terms of interface design. However, some users have noted that app responsiveness could be improved, suggesting that software optimizations could enhance the user experience.

Voice Assistant Compatibility

The compatibility with popular voice assistants like Alexa and Siri is seamless, allowing users to control their home temperature with simple voice commands. This feature is particularly useful when hands-free control is desired, such as during cooking or cleaning activities.

Pros and Cons Analysis

The Ecobee3 Lite Pro's affordability, smart home integration, and energy-saving features are significant pros. However, the lack of geofencing, the requirement for a C wire, and the additional cost of separate remote sensors for multi-room monitoring should be weighed against these advantages.

Comparison with Competitors

When compared to similar products on the market, the Ecobee3 Lite Pro holds its own, especially in terms of price and compatibility with smart home devices. However, competitors may offer features like geofencing or more vibrant displays, which could sway users looking for those specific functionalities.

Value Proposition

At a price point of $169, the Ecobee3 Lite Pro Smart Thermostat presents a compelling value proposition. It offers a comprehensive set of features that cater to the needs of most smart home enthusiasts while being mindful of budget constraints.

Final Thoughts

The Ecobee3 Lite Pro Smart Thermostat is a strong contender in the smart thermostat market. Its compatibility with a wide range of smart home devices, user-friendly interface, and energy-saving capabilities make it an attractive option. While it has its drawbacks, such as the lack of geofencing and potential additional costs, its strengths make it a product worthy of consideration for those looking to enhance their home's intelligence and efficiency.
