I was waiting for you to confirm the possibility of PICO integration. Now I have to go shopping for a Pro version myself. Here’s my incomplete but initial thoughts:
Scenes: sounds perfect
Ramp Rates: I think having a setting we can change in the device config is enough. Making it adjustable based on context, while useful, will probably create more problems that it will solve (from a coding/stability standpoint). Maybe something to add later after basic functionality confirmed.
Pico Control: the only reason I will invest more money and buy a pro version of the hub. I think they should be separate devices and setup like a basic Button Controllers (similar to Aeon 4 button zwave controller). This will give the controller multiple use cases as there are a bunch of smartApps that already exist for this device type.
Just my 2 cents. Good Luck and thanks again for your work on this!!
