Yep I still don’t own a TP-Link camera So I have no direct plans to add them.
Looking at the reversed engineerd information it looks similar communication as other TP-Link devices. So if you manually configure a HS100 you might be able to see the status and even might be able to switch the camera led on and off. I don’t know what actually switching on or off might do or if there are any other commands possible. Basic device status or maybe some other commands might be something to add to the binding. But streaming would be much more complex I would guess and might be better serviced by the ipcamera binding. Maybe extending that binding with specific support for tplink to be able to easier get the correct url or let the tplink binding provide the url in some way to the ipcamera binding.
