pip install esptool

Press and hold the BOOT button (GPIO28) on your ESP32-C5 development board, then press and release the EN (or RESET) button. Release the BOOT button when the chip is powered on. The chip will now be in Joint Download Boot mode.

esptool.py --chip esp32c5 --port /dev/cu/usbmodem5A7A0352731 read_flash 0x0 0x1000000 <OUTPUT_FILE>.bin

Gate Opener

Ladies and Gentlemen, Boys and Girls and for my next (first) trick I will open the gate with nothing but my mobile phone and maybe a microcontroller and relay or the like in the gate opener.

OK carrying a gate opening remote is a PITA. I don't drive most places, I uber or taxi or get a lift.

So I can't just leave a gate opener in the car's console, because chances are pretty good my partner will be in the car in a different location to me when I want to get in.

And the gate opener is too big to comfortably go in a pocket without getting damaged over time - ask me how I know.
So I want to add a "little something" - probaby an ESP32 or a Pi Zero or Pi Pico to open the gate for me.

I believe you can open the gate by applying a certain amount of voltage (I'm not being coy, I just can't rememeber the number off the top of my head) to a certain terminal on the gate opener controller.

So I think a Pi or and ESP 32 with a relay wired into a coupla GPIO pins should do the trick.

Worse case I take one of the old broken gate opening fobs - the battery doors break, the PCB should be fine still - take the PCB and replace the switches with a relay or a transistor, again wired to the GPIO ping of an ESP32 or a Pi etc.

Bung it on the IOT home network, write an app that can run in a container either in AWS as a Lambda function and Bob is your mother's bruvver - or so it has been alleged.

What say you? Seem feasable? Any one else done it who can tell me to do it better?

These are the fobs I would canabalise: https://www.aliexpress.com/item/1005008269545680.html
