⁠Sniffing remote control codes

Before using the service you have to find out the codes that your devices are listening to to make them turn on resp. off. Fire up a container to sniff the codes:

docker run --rm -it \
    --name sniffy \
    --privileged --cap-add SYS_RAWIO --device=/dev/mem \
    hazard/rpi-433rc:latest sniff -g 27

You should see that the sniffing tool has started. If your gpio pin is not 27 (default), you can pass a different one. Push the buttons on your remote control like a madman and note the results for the different devices (on / off codes). If you are done Ctrl + C out of it.

⁠Rest http server

Create a device.json file to configure your devices with the sniffed codes. Content should look similiar than this:

{
    "device1": {
        "code_on": 12345,
        "code_off": 23456
    },
    "device2": {
        "code_on": 66567,
        "code_off": 45675
    }
}

Where device1 and device2 are the actual names of the devices. Be creative ;-) code_on and code_off are the actual codes you sniffed before.

docker run --rm \
    --name rpi-433rc \
    -p "5555:5000" \
    -e CONFIG_DIR=/conf \
    -e GPIO_OUT=17 \
    -v <path/to/your/device.json>:/conf/devices.json \
    --privileged --cap-add SYS_RAWIO --device=/dev/mem \
    hazard/rpi-433rc:latest serve

You can change the GPIO_OUT if you are using a different one than me. Nicely done. Thanks to host port routing you should see the swagger ui when navigating to the url http://localhost:5555⁠. Feel free to try the different endpoints.
