I use Raw Socket (in beta) in the Kasa Plug, Bulb, and Switch drivers (as well as UDP). Some of the interesting items I have included is:
Concatenation of multi-message replies,
Working without socket status messages from client (it does not generate these),
Error handling (to assure delivery of commands to client).

PS: One thing I am interested in is the Hubitat resource utilization of UDP vs Raw Socket for my system. I can do both; however, Chose raw socket because of user desire for quick polling. But I can create a hybrid with minimal code impact.
Update: I no longer user raw sockets.
