It does require a separate SmartSensor for more accurate room-specific monitoring, which is an extra cost to consider. Installation is straightforward, typically taking around 45 minutes, and the included Power Extender Kit makes it accessible for homes without a C-Wire. However, while the thermostat is designed to last, it does require a lithium-ion battery for its operations, which some users may find inconvenient. The ecobee Smart Thermostat Enhanced is a strong candidate for anyone looking to upgrade their geothermal heat pump system with a programmable, energy-efficient thermostat, but be prepared for potential additional costs with optional sensors.
