Your Particle account is not tied to Garadget’s organization. Without it it is still possible to add Garadgets to your vanilla Particle account via CLI, but my server will not receive events reported by your units and as result there will be no notifications.
I discussed the issue of mixed use of accounts with Particle engineers and I’m sure they’ll figure it out eventuall. The best course of action for now is to use separate account for Garaget units. When there’s a solution you’ll be able to consolidate them in one.
If you’re into this kind of adventure, you can handle the notifications yourself via web hooks, IFTTT etc.
I’ll be happy to answer any questions so don’t hesitate to ask.
