openers
Gate and garage-opening code for Raspberry Pis and ESP32s.
The plan is to be able to open my gate and garage remotely, by driving simple single-frequency transmitters first from a Raspberry Pi, and later from an ESP32.
Commandline examples
# Open (my) gate
sudo chrt -f -r 99 openers secplus transmitv2 --rolling=123456789 --fixed=1222022221850123456789 --pin=12
Building
For (my) Raspberry Pi Zero W
GOOS=linux GOARCH=arm GOARM=5 go build . && scp openers pi@pizero:openers
Sub-packages
secplus
Package secplus implements Security+2.0 encoding.
Writing it would not have been possible without the work done by @argilo in
decoding the Security+2.0 protocol for their excellent Python secplus
package, and the helpful debugging by
@acoursen in understanding longer transmissions (argilo/secplus#6).
megacode
Package megacode implements MegaCode encoding.
Writing it would have been difficult without the work done by CuVoodoo in describing and decoding the MegaCode protocol on their excellent MegaCode hacking page.
gpiod
Package gpiod exists simply to wrap github.com/warthog618/gpiod on Linux, and provide a dummy implementation on other platforms, so that things will still compile. Only functions and types actually used by the other code have been added to the dummy implementation.
Todos
Next steps for my development (likely to get done soon):
- Security+: Write code to actually transmit by driving a Raspberry Pi pin
- Write a commandline app for testing
- Implement MegaCode encoding
- Implement MegaCode Raspberry Pi transmission
Future (PRs welcome!):
- Convert these TODOs into issues
- Add Security+2.0 decoding
- Add Security+ encoding/decoding
