Systems and methods for using a wireless sensor in conjunction with a host controller are described. An illustrative system can include a host controller, a wireless sensor device, and a decoder in communication with the wireless sensor device and the host controller. The host controller may include a remote sensor input that normally would be connected to a wired remote sensor having an expected sensor characteristic. The decoder may receive a wireless signal from the wireless sensor device, and may provide an output signal to the remote sensor input of the host controller that replicate or mimic signals that would be provided by a wired remote sensor having the expected sensor characteristic.
