Recently I created a VLAN for all the IoT devices on my home network. After everything settled down, the X1 can't be discovered from a different VLAN. My router (Unifi) runs an mdns repeater and all the other smart devices on my network are working (HEOS, Alexa, Hue, etc). I can ping the X1 from other VLANs, and the app discovers the X1 just fine if I discover from the new VLAN. What is the X1 doing differently and why can't I use it across VLANs?
