Need help with Vista 20p integration

So I spent a few hours on here last night trying how to figure out how to integrate my ADEMCO Vista 20p into smart things.

Could someone please point me to the right direction: Several of the solutions I looked are no longer supported.

  • The integration with the things hub

  • I really don’t want to have a Pc running 24/7, I am completely okay with purchasing raspberry pi; however, I cannot find any detailed instructions how to integrate it with any of the users soultions that still work.

My programming skills leave a lot to be desired.

I am wondering if I should just bite the bullet and use the smart things sensors, but my detached garage that’s prewired with adt is too far from my wireless connection. So I would be sacrificing that.
