after some measures the best is this
i use a cheap chinese QC charger. the regulator check the adapter and auto set 12V IN
you can regulate constant Vout. with ethernet adapter i obtain all false on system with 5.3V
THEN we need a costant Voltage on power supply of 5.3V
Max current at 100% load of Homey is 1.3-1.4A then is not absolutely the problem.
