Discovery

My RT-590 broadcasts on udp:6667 periodically. I wonder if HA could discover the grill?

The tplink component appears to provide some custom discovery logic and may be useful as an example.

The tuyapower library can process the broadcasts and provide the IP address, device ID, protocol version and a product ID but the local key is not in these messages.

I used the script below and was able to discover my RT-700 in the past (few months back), but running that script now doesn't discover my grill. Might have been an update to firmware on the 3.1 version grills?
