Score: 86/100
Emerson Sensi Touch 2
Score: 77/100Rankings

The ecobee Smart Thermostat Enhanced delivers up to 26% energy savings, geofencing and radar occupancy detection with a vibrant 4-inch touchscreen. It lacks air-quality monitoring and multi-zone support, which may limit advanced users. Ideal for single-zone homeowners seeking strong energy-saving features and wide smart-home integration.

Emerson's Sensi Touch 2 offers a full-color touchscreen and Alexa voice control with a focus on privacy and easy DIY installation. It mandates a C-wire and currently supports only Alexa, limiting broader smart-home ecosystems. It fits well for users who prioritize a sleek interface and straightforward setup.

Professional reviewers commend the Enhanced model for its proven energy-efficiency, radar-based occupancy detection and extensive voice-assistant integrations, calling it a trusted, planet-friendly choice. They note, however, that it misses premium features such as air-quality monitoring and bundled remote sensors, and that installation can be a bit daunting for novices.
Everyday users appreciate the thermostat's intuitive touchscreen, sleek compact look and the quick payoff from energy savings, describing it as very user-friendly. Common frustrations revolve around the need to follow detailed setup instructions and the lack of extra sensors found in higher-end models.

“Very user-friendly with many features; compact and attractive on the wall; effortless control and energy savings (pays for itself quickly).”
