This is a super simple home automation server I whipped up for my own purposes.
Server and nodes are written in Kotlin and utilize the Ktor framework.
UI is written in Typescript and built on the Angular 2 and Ionic frameworks.
To install the server, run gradle distTar and take the distribution file under build/distributions/home-automation-server-<version>.tar and untar it in a directory like /usr/lib.
To add the UI to it, make sure you have npm installed. Install Ionic by running npm install -g ionic. Build the UI by running ionic build --engine=browser. Finally, copy the files under the ui/www directory to wherever you untarred the home-automation-server build in a new app directory.
Crank it up by running bin/home-automation-server.
Why didn't you use OpenHab2 or some other automation server that already does this?
I did for a while, but it didn't do everything I wanted. I have the power to code and as it so happens love doing it.
Why did you write this in Kotlin? I thought that was just for Android.
Once I tried it out, it was hard to go back to Java anywhere. In fact, I've gotten many teams I work with in Amazon to convert to it and they're all backend services.
For me, it's just a great JVM language that is significantly better than Java.
Are you going to spend tons of time making this totally generic and a competitor to other home automation frameworks?
Unlikely. If you find it useful, feel free to use, clone, or contribute. I don't really have the time to make this any more than I need it to be.
Your code sucks. Why did you hard code strings everywhere and not make it more generic?
This isn't something I would ever put in production at work. I took some shortcuts as it's good enough for my purposes.
