Ubiquiti Unifi mDNS Auto Discover Issue

If mDNS is unchecked then Homey and ESPHome will not auto discover new devices

If you have different networks that Homey and ESPHome devices are on, then you will need mDNS working across both networks and firewall rules allowing access between them. Below are guides for using your PC and the Unifi iOS app to fix this issue.

Method 1: Browser

1. Log into your Unifi network through your default IP address which is usually 192.168.1.1
