my subnet is 192.168.0.0/24. I’ve been using Zerotier for remote access so no ports are open on my router, firewall is enabled. These IP addresses don’t match my Zerotier subnet either.
Any idea what this could be?
I’m using the Mosquitto mqqt broker, only mqqt devices I’ve installed (to my knowledge) are the Ring doorbell and Hisense AC integration - Ring is working, Hisense is not for some reason.
