I leave my house for several days at a time on a frequent basis.   For security reasons, I would like to enable AWAY mode for several light switches on my departure and then disable AWAY mode for these switches when I return.  Ideally I would like to use geo-fence to make this automatic.  But I would be happy if I could just manually turn somthing on  (group? scene? smart action?).

Posssibly enhance the GROUP capability so that AWAY mode could be enabled for several devices rather than simply turning devices on/off?
