31 years old and medically retired (Air Force) where do I start

Hey guys, I’m 31 and retired and I’m getting bored. Before you say “get a job or volunteer” I REALLY can’t . If I wanted to learn to make these apps, where do I start? Money for material isn’t a BIG problem, if I need to pay for a couple courses, no problem. I do have a Lynda.com subscription if that would help.

Thank you

First of all, thanks for your service. Second, you need a Hubitat hub. It requires an Ethernet and 120v connections. It maybe good to get a Github account (github.com). There are examples on there of others code (apps). You should search "Hubitat" and even "Smartapps" or "smartthings". SmartThings is the Samsung hub but code is close to HE (Hubitat). Another approach is to use the HE built in app generator called "Rule Machine". I never used it since I write my own apps but it could make life easier. Once you have a HE hub, you go to apps and then in the top left "Add Built-in App".
Make sure you ask questions on this forum. People will help. There is also documentation which you can access via the HE hub. Additionally, Google searches can help.

Thank you. I have the hub and github already, should I take a python 101 course first?

Hubitat uses a subset of groovy for the apps/drivers not Python. Although Python is a great language and I use it all the time it won't help with Hubitat.

What’s the “foundation” of groovy. There doesn’t seem to be like a groovy 101

Java.

As mention Groovy sits on top of Java. Here's the main page for you.

So i should do a Java 101 course first?
