I have my shellys and other iot stuff in different vlans then my "trusted" network (desktops/laptops/phones).
I have mDns enabled and forward uPnP and CoAP packets from the IoT lan to my trusted lan (also IGMP snooping on both vlans) but can't add them to app (not using cloud because i use MQTT to Home Assistant - that part uses routing so it works great).
Is it possible to know how the App is searching the devices?
Even if i had them by IP on the app it doesn't work!
Note: using Ubiquit Dream Machine Pro.
