Make sure you’re living as comfortably as you can be with the ecobee SmartSensor Motion Detector. This smart thermostat measures the temperature of whatever room it’s in. In fact, this smart gadget can measure both temperature and occupancy. Pair it with the SmartThermostat and SmartCamera from ecobee to ensure your home’s entire system works together. Moreover, one of the great features of this remote sensor is that it has a long battery life of up to five years. So you really don’t need to worry about whether it’s working or not. Furthermore, sold in a pack of two, this sensor works up to 60 feet away from the thermostat hub. If that doesn’t cover your entire living space, you can connect up to 32 SmartSensors.
