I just got the HA Yellow PoE kit with CM5 module. Installed the CM5 module and the heat sink. Now to load the software, instructions say to set the JP1 to USB, then hold down the USB-C Rcvry button and power ON the device. I am using 12V 3 Amp power adapter. As soon as I turn the power ON, all 3 LEDs blink and keep blinking.
My 12V Power adapter is faulty. Switched to another one and it is working now. My apologies for the false alarm.
