Ecobee SmartSensor vs X-Sense Smart WiFi Indoor Thermometer

For general monitoring, the X-Sense Smart WiFi Indoor Thermometer wins, with a lower price, a 5-year warranty, humidity sensing and more alert types via its base station. The Ecobee SmartSensor is better rated and adds occupancy detection and a five-year battery, but it only works as an Ecobee thermostat accessory.

The X-Sense Smart WiFi Indoor Thermometer is a standalone remote monitor that connects via a base station and measures humidity, while the Ecobee SmartSensor is a proprietary accessory that only pairs with an Ecobee thermostat and reads temperature and occupancy, not humidity.

The X-Sense Smart WiFi Indoor Thermometer carries a 5-year warranty, longer than the Ecobee SmartSensor's 3-year coverage, giving it more protection out of the box.

Buyers who want affordable remote monitoring of cabins, garages or greenhouses through a base station, with humidity readings, low-battery alerts, a long warranty and Alexa support.

Ecobee thermostat owners who want occupancy-aware comfort balancing and a five-year battery, and who do not need humidity, a screen or standalone remote monitoring.
