@tekno-yanqui When I tried to add your reference to eth-w5500 and link to github my compiling returned with an error that esphome needed platform keys. Unfortunately if you try to add platform keys then it says that platform has been removed from configuration, please configure correctly. Please see my thread: Entities available on wifi component but not on ethernet component - Configuration - Home Assistant Community
as my device is connecting to network and log is being reported but nothing (entities/devices) is being discovered in HA
