A HVAC controller located within a building zone includes a housing, a wireless radio, a controller monitor, a temperature sensor, and a temperature compensation module. The wireless radio is contained within the housing and is configured to transmit data via a wireless HVAC network. The controller monitor is configured to detect wireless activity of the wireless radio, the wireless activity generating heat inside the housing and causing a temperature inside the housing to exceed a temperature of the building zone outside the housing. The temperature sensor is configured to measure the temperature inside the housing. The temperature compensation module is configured to determine a wireless heat rise resulting from the wireless activity, to calculate a temperature offset based on the wireless heat rise, and to determine the temperature of the building zone outside the housing by subtracting the temperature offset from the temperature measured inside the housing.

The system includes an electromechanical relay with an energizeable coil and a microcontroller configured to synchronize energizing the coil relative to a voltage zero crossing time based on a relay contact close time and relay contact bounce time measured particularly for the relay.

A door system includes a door module and a door sensor. The door module is configured to be installed in proximity to a motorized door opener and includes communication module, door close/open module, a door status module, and a housing. The communication module is configured to receive user commands through an Internet router from a remote door server. The door close/open module is configured to direct the door opener to open or close the door in response to a user command received by the communication module. The door status module is configured to send door status information to the remote door server. The communication, door close/open, and door status modules are integrated within the housing. The door sensor includes an active sensing component configured to be physically coupled to the movable door and is configured to collect door state information and transmit the door state information to the door module.

An energy control network may include a number of load control devices, such as dimmer switches, multi-button selector switch, occupancy sensors, and remote controllers, among others. These load control devices may be configured for wireless communication. Other wireless devices, such as laptops, tablets, and smart cellular phones may be configured to communicate with the load control devices of the energy control network. The load control devices and the other wireless communication devices may also be configured for Near Field Communication (NFC). NFC may be used to provide a load control device with its initial default configuration and/or an application specific configuration. Also, NFC may be used to transfer a configuration from one load control device that may have become faulty, to a replacement load control device. And NFC may be used to provide and trigger commands that may cause a load control load device to operate in a predetermined manner.

An illustrative embodiment disclosed herein is a system including a mobile device configured to receive a user input requesting a first action to be performed by a refrigeration controller and encode the first requested action into a first command frame formatted for wireless transmission. The first command frame includes a first command code identifying the first requested action. The mobile device is further configured to send the first command frame from the mobile device to the refrigeration controller. The system further includes the refrigeration controller configured to extract the first command code from the first command frame, map the extracted first command code to the first requested action, and perform the first requested action in response to the mapping the extracted first command code to the first requested action.
