My wife and I both have a car each, but we also have a third car (4x4) that we share.
This is used when one of us takes the dogs out, or because the weather is bad and one of us has to go somewhere and doesn’t want to chance taking a 2 wheel drive.
I was recently reading this thread:
https://community.smartthings.com/t/3-or-more-state-virtual-button/78073/7?u=cobra
and it got me thinking…
… Car at home… Wife took the car… I took the car… we both took the car…
4 ‘states’ for a virtual indication switch
So after ‘tweaking’ the DTH to show: Driver1, Driver2, On Drive & Both I created a little smartapp to try and indicate ‘who took the car’
I’m adding both the modified DTH and the smartapp here in case someone else might find it useful or as a building block for something else.
I have only been testing for a few days but everything seems to work quite well.
Always welcome feedback (good or bad 
)
I’m afraid I’ve been rather sexist with the icons for the DTH
Driver 1 shows a man and Driver 2 shows a woman… easily changeable

* then modified by Robin Winbourne for use with a dog feeder to give access to four 'states'.
* Then modified by me (@cobra) to change the text/colours/icons to be able to use it to show who took a shared car :)

There is currently one scenario that I have discovered that causes problems…
If the wife is out in the shared car and I take my car out… the app decides that we both have the car…
I’m working on adding our other two cars into the mix so the app can track if we took our own cars or the shared car…
