rv-homekit

rv-homekit

rv-homekit is a small GO app used to act as a proxy/adapter between the OneControl interface from LCI and Apple's HomeKit

It is designed to be able to run on a raspberry pi plugged into the ethernet port on the OneControl gateway and joined to your own WiFi network if they are separate.

Installation

First you need to prepare a RaspberryPi as your host for the application. The OS that I'm using myself is Ubuntu 20.04 server. You will need to use a RaspberryPi 3 or 4 and the 64 bit version of Ubuntu.

If you have a separate WiFi network that you use for your devices configure the wireless on the pi to connect to that network.

Download the rv-homekit app from https://github.com/jgulick48/rv-homekit/releases/download/v0.0.1/rv-homekit and save it in its own directory.

Building

If you are building from the source code for a Raspberry Pi you will want to use the following command.

env GOOS=linux GOARCH=arm GOARM=5 go build

Configuration

There are a few settings that need to be configured and saved in a config.json file in the same directory as the application.

The config file needs the following information:

• Bridge Name (This is what will show in homekit as your device name.)
• Bridge Pin (Must be 8 digits, this is the pin to add the bridge to HomeKit)
• OpenHAB host. (Should be http://192.168.1.4:8080)
• Port Number. (This can be any port but must be exposed to your network like below.)

Here's an example config.

{
  "bridgeName": "My RV",
  "openHabServer": "http://192.168.1.4:8080",
  "pin": "00102003",
  "port": "12321"
}

Running

Using Shell

Initially running is done like a regular application. Enter the folder where you downloaded rv-homekit and created the config.json file and run ./rv-homekit

If you wish to run this unattended use nohup to keep the application running after closing the ssh session. nohup ./rv-homekit

Using Docker

Make a directory for the application to store its configuration and item information. One example would be /var/lib/rv-homekit. Download the config.json file to this location using the following command wget https://raw.githubusercontent.com/jgulick48/rv-homekit/master/config.json This config file needs to be mounted as a volume in the container under /var/lib/rv-homekit If running on a raspberryPi use the arm release of the docker image. An example command is as follows:

docker run -d --volume /var/lib/rv-homekit/:/var/lib/rv-homekit/ -p 12321:12321 --network host jgulick48/rv-homekit:arm-latest

If you have a V.E. Direct serial cable hooked up to the unit add this as a device to the docker container.

docker run -d --volume /var/lib/rv-homekit/:/var/lib/rv-homekit/ --device /dev/ttyUSB0:/dev/ttyUSB0 -p 12321:12321 --network host jgulick48/rv-homekit:arm-latest

If you want to have the container run when the docker service starts up you can add --restart unless-stopped to the run command. This will make sure the container starts up again if it wasn't manually stopped.
