Two quick comments after using the SmartThings for a few days:
I bought ZWave wall switches a month or two ago in prep for SmartThings and paired them to some GE/Jasco ZWave remote controls. In order to pair the switches to the SmartThings, I had to delete it from the remote control, as expected. I believe ZWave devices can only have a single “master” controller.
I’d like the ability to pair the remote control with the SmartThings hub as a slave so I can still control my lights via remote control (when in bed, it’s easier hitting a button on a remote than it is bringing up my iphone/ipad).
Alternatively I’ve thought of just using a contact sensor or something to trigger my bedroom lights while in bed :).
I don’t know if there are plans for this or not, but I’d like the ability to create a virtual device (thermostat, for example) in the SmartThings cloud (not virtual in the sense to test in the IDE, but virtual in the sense that it is emulating a real world sensor). I could update its status via an API. For example, I have a USB weather station at home that is connected to a raspberry pi. The weather station outputs the interior and exterior temp/humidity/etc every 5 minutes. I could easily have it push this info up to the SmartThings cloud. If SmartThings could then recognize that input as a sensor, I could interact with it as part of the SmartThings world.
