This adapter offers dongle extension capabilities to TaHoma switch, enabling the box to get additional protocols, and thus extending its compatibilities.
Once the USB adaptor is plugged in, a USB protocol module can be added (to be compatible, the protocol must be integrated into the TaHoma app). For now, only EnOcean protocol is compatible which means that only an EnOcean module can be added (ref. 1824033).
