From family member, I got Homey 2019 Pro, which has been damaged by over-voltage (9V but maybe 20V) due to the used Power-supply with PD functionality, connected over cheap measuring device, that caused over-voltage.
Visually there is no visible damage, maybe audio amplifier but not 100% sure.
When connected to power supply, Homey power consumption is only 0.3A and no LED - nothing is heating, including CPU nor mem.
Seems that modules like ZigBee, Z-Wave, etc. get’s 3.3V, LED gets 5V as well as audio amplifier…
There is console, RX/TX/GND, tried connecting it via CP2102 USB 2.0 to TTL UART Module but got nothing - not sure if anyone got some experience ?
Also, any other tip ?
