Just as HomeKit can control the Caseta/Serena system, it would be great if it can also work the other way i.e.. a Pico remote can activate HomeKit scenes. As an example I'd like to have a Pico near my front door programmed with an "AWAY" scene which would set the lighting and shades to the settings I've set (I know that is possible now) but also set the thermostats to my away settings, lock the doors,close the garage etc. And a "HOME" button that changes everything back when I return home.
What's nice about HomeKit in iOS 10 which I've been using in beta form is that all of your HomeKit components are in one place so it's very easy to program scenes. I'm hoping this can be added once Homekit is officially released next week. And I love how well the Pico's integrate so nicely with our "dumb" switches, so it would be a great addition IMO.
