Although I use my full-feature Multi-Place app, I suspect there may be some here that would benefit from a lightweight Google Traffic device, which would simply spit out how long a trip would take (and the best route) from point A to point B when triggered. And populate the result in the device's attributes.
Example: when a switch is turned on, the device updates its attributes indicating how long your commute to work is and the best route to take.
If there's enough interest, that should be pretty easy for me to do since I've already got all the calls I need in the other app. Would you find use for this?
