Fixed. I noticed I was running an older version of the software. Uninstalled completely and reinstalled, worked fine.

Where would be the best place for an Arduino newbie to post to get some assistance? I'm looking at Gateways and i'm unsure which direction to take, and where would be best to post. Would this be OK? https://forum.mysensors.org/category/13/development

Done.

The MySensors library is missing from the arduino library manager again. Should I just log a new issue and reference the previous one?
