Funny, because when I got my Almond 3, which works the same way, I thought it was odd... but wihtout a separate button for adding Z-Wave vs ZigBee, I got pretty used to just handling everything together. That is kindof the beauty of it. If you have a Z-Wave dongle, great! It can add things in and they will work just fine. If not... then you can use the ZigBee with no real change. Mix and match, or not. No separate workflow.
