I have an ESP32 development board running ESPHome connected to my RT-88U router (running Merlin 386.7.2). The connection is via the board's onboard wifi using a static IP. It's definately connected. I can ping it and otherwise access it. However, it does not show up in the Router's Network Devices list. I think it is in the offline list I can see in Parental Controls. Is there something to do to make it appear as connected?
