Some ecobee thermostats can be installed without a C wire because select models include a Power Extender Kit for hardwired installations. Requirements vary by model and HVAC system, so confirm the available wiring and use the included wiring guide to determine whether an accessory is needed.

Room sensors detect temperature and occupancy in selected areas, then share that information with the ecobee thermostat to help balance comfort throughout the home. When a sensor identifies an occupied room or a hot or cold spot, the thermostat can adjust its temperature control strategy, support Follow Me mode, and help manage energy use when rooms are unoccupied.

ecobee thermostats can integrate with Alarm.com, Apple HomeKit, Amazon Alexa, Google Assistant, SmartThings, and IFTTT. This connectivity helps installers add thermostat control to compatible smart home, security, and automation systems.

Before installation, review the HVAC system, available wiring, power requirements, and accessory connections, including whether a C wire or Power Extender Kit is needed and whether the system supports one- or two-wire accessories. During configuration, set up the thermostat for the customer’s HVAC equipment, place room sensors where they can monitor occupied areas or hot and cold spots, and confirm smart home integrations, schedules, and occupancy settings.
