It is not yet available, as the Beta1 Release is strictly for hardware (structure/electronics), but will be released with a future release. We are hoping for community engagement and contribution on developing the software.
That said, a ton of builders have written their own already and if you reach out on the Discord server, I’m sure they would be happy to help you.
Please note the software will be hosted in a separate GitHub repository than the main OpenHornet repository.
