XRF Sync is a remote monitoring and management (RMM) tool, with the ability to permit messages between different endpoints in specific scenarios. It was originally built to support the HAController home automation software, however, today the preferred client is XRFAgent which can, in turn, pass commands through to HAC via LocalQueue mode.
