Ok I think this is stable enough now to release as a beta. This is a package manager for Hubitat that makes installing and managing your apps and drivers easier. It allows you to install an app (for example Ecobee suite that has 13 apps and 2 drivers) with "one click" instead of having to do each one manually. It also automatically checks to see if new versions of anything installed using this app are available. As time goes on I hope more developers will come on board (if apps you use aren't supported, feel free to ask the developer, I'm happy to help them get setup!), but right now my own, @aaron, @bptworld, and @storageanarchy have all been starting to release our apps/drivers using this.
This is definitely beta software. I haven't experienced any serious issues but during testing people had reported that it installed duplicate apps, wasn't detecting updates properly, etc. I think I've fixed most of the serious issues but I'm sure there are still bugs.
You can find the code and documentation at GitHub - dcmeglio/hubitat-packagemanager
Developers, you can also find information there on how to add support to your own apps. There is a little command line tool I wrote that you can use to build the manifest files (there is also now a converter if you happen to have apps that use the SmartThings Community Installer for your apps).
If you find bugs or have suggestions please report them as issues at GitHub - dcmeglio/hubitat-packagemanager as this will be the easiest way for me to keep track of them.
