I like the concept a lot but would like to see some enhancements. All of my comments are assuming that I know what I am doing. I apologize in advance if I my suggestions are the result of not understanding the plug-in.
I am using an iPhone.
1. I find it inconvenient to unlock my phone, open the app and turn-on the voice control. Voice control is great once I get it turned on. Frankly, it is easier to open the app and then just select my device or scene and touch the icon to operate a light if I am only working with 1-2 lights. It would be a lot more convenient if the voice control would turn on in the background whenever I unlock my phone. I use geo-fencing and your location services so I would further like to restrict the "auto on voice control" to those times when my phone is within the location zone.
2. I have some lights set to ramp to a set brightness, say 50%. I would like to have a voice command which would allow me to ramp up to 100% or even some other number between 1%-100%. Also would like to dim to a level that I would command. Dim could work by using the reductions % that are set into MobiLinc.
