Also note per this thread we’re not currently reviewing submissions. Adding your device to our ecosystem is more than just merging a pull request. We’d need to test it in our lab, make it available to our QA teams for regression testing, train all of our support agents on functionality and troubleshooting, etc.
I’d love it if I could just merge your pull request, but unfortunately there’s a lot more to it and we’re not reviewing submissions at this time.
