A system for monitoring and controlling building equipment includes a near field communications (NFC) tag, a temperature sensor, a mobile device, and a controller. The NFC tag is located within a building space and stores a tag ID uniquely identifying the NFC tag. The temperature sensor is associated with the building space and configured to measure a temperature of the building space. The mobile device reads the NFC tag and obtains the tag ID from the NFC tag via NFC. The controller receives the tag ID from the mobile device and uses the tag ID to identify the temperature sensor associated with the building space. The controller receives the measured temperature from the temperature sensor and provides the measured temperature to the mobile device. The mobile device displays the measured temperature via a user interface of the mobile device.
