Somfy blind motors cannot be assigned to a room

[DCEM]

The problem

Somfy motors will return None as serial number via the Velux KLF-200: Handle devices without serial numbers.

This serial is usesd as unique id here: core/homeassistant/components/velux/init.py#L114

Could it be reasonable to return the node name instead of None?

            if self.node.serial_number:
                return self.node.serial_number
            elif self.node.name:
                return self.node.name
            else:
                return "velux_#" + str(self.node.node_id)

Hey there @julius2342, mind taking a look at this issue as it has been labeled with an integration (velux) you are listed as a code owner for? Thanks! _{^{(message by CodeOwnersMention)}}

Hello. I have this same issue. Could it be possible to create a unique ID for HA?
