I was idly scanning my LAN last night, and found that my BT Whole Home Wifi discs all contain MQTT brokers. I see an open topic "owl" on each of them, with 4 frequent message types. The messages I've seen this morning are:
msg_type: 1, msg: "periodic msg"
msg_type: 2, msg: "sta join, mac=<MAC address>" or "sta leave, mac=<MAC address>"
msg_type: 3, msg: "ap data update"
msg_type: 4, msg: "update led status"
Are there other topics?
If so, are they protected?
If so, what are the credentials to subscribe to them?
What metrics can I retrieve?
