We need an UPnP Interface, i.e.
1. Announce the presence of devices via SSDP
2. Describe the devices (e.g. according to HVAC, Binary
Light, Dimmable Light device profles)
3. Make the devices controllable via SOAP
4. Event State changes using GENA
We plan to support UPnP Device Architecture 1.1

Yes, the choice of UPnP would come from its lightweight
nature and widespread adoption.
