What is Vera's black dongle for? What happens if I lose it?
The dongle is plugged into one of Vera's USB ports and contains the Z-Wave chip needed to talk to your Z-Wave devices. When the dongle is removed, Vera cannot communicate with any Z-Wave devices, though IP Cameras, Wi-Fi and other non-Z-Wave functions still work fine. Also, when you pair Vera to Z-Wave devices (that is, 'Add' Z-Wave devices), that pairing information is stored in the dongle. So, if we ever need to replace your dongle, you'll have to reset the Z-Wave devices and add them again. Beginning with Vera2, a dongle is no longer needed.
