New Pitool is coming & apparently valve is working with them to fix it since it broke after your march article when it worked fine. Cas & chary so far seem to have Unicorn as they had 0 problems & no workarounds needed.
With these controllers being new will take sometime to get everything in place. No different than early issues with Steamcontroller & steamlink when first released.
What would be cool (off topic) is to hack a driver to use Oculus touch wireless with tracking pucks.
