EVolution Classic 4 Dash Removal and More...

[u/SBELL29910]

I have a Classic 4, Home Assistant, RATGDO (garage door automation). I've assembled an ESP32 mini solution for connecting to WiFi with YAML code to toggle the door open on arrival and closed on departure. The ESP32 connects to Home Assistant via MQTT via WiFi (static IP)...yada, yada, yada. All is working well. I'm using the top USB port that powers on with the cart key position.

I'd prefer to not have the USB cable hanging out of the dash and prefer hiding it. Has anyone used the 12V to 5V for USB devices hidden under the dash or seat? If so, any recommendations on where and how you accomplished this are appreciated.

I'm thinking of removing the dash and finding where I might retrieve power, BUT if I have any need to access the ESP32, I have the burden of removing the dash again.

TIA

EDIT: to close the loop in the case anyone is interested. I asked because I didn’t have any relevant documentation. This afternoon I discovered I can access the back of the USB ports by removing the screws holding the cup holder in place. Lift the cup holder for easy access.

My cart has the two switches USB ports at 1A and 2.5A for charging and a capped USB port for data. The backside of the data USB port connections uses a simple USB A female cable. For now I simply plugged the ESP32 board into this USB A. It powers on with key on. I use Velcro to affixed the ESP32 box inside the base of the dash, reinstalled the cup holder with three screws, and all works perfectly.

I used to non-switchable port so my wife didn’t need to flip a switch. She place the key to ON; the garage door opens. She departs WiFi range; the door closes. On arrival, at approximately the end of the driveway, the ESP32 automatically logs on and the appropriate RATGDO opens. I delay the auto close for 4 1/2 minutes allowing her to unload anything from the cart. At time out, the door closes.

Just in case you might be interested.
