I think publishing the integrated apps and drivers as Open Source (I'm not talking about the core software) would bring a huge benefit, as it would allow the community to contribute and even help finding bugs easier.
I know that as of now only examples are published this way; my intention with this topic is to officially bring this up as a non-functional feature request.
This has been brought up more than a few times over the past couple of years and the answer's been... (paraphrased: ) "Hubitat is not Open Source, and no intent on making it so. Examples have been published."
It would be great if your request pushed the founders over the 'line' and they chose to do this.. but it doesn't seem likely, so I wrote this to prepare you for the likely answer: silence (since it's been answered before,)
