Allow setting of MAC address for devices that allow setting it (ESP32) #2124
Description
It would be nice to allow setting of the MAC address either via a build flag or via the Web GUI.
I know this is possible for ESP32s and is useful for me when I want to fully clone a device
It's not a high priority but if there is an interest, I might be able to write a PR at some point.
So just judging general interest...
