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.
