email and calendar triggers

Hello,

I feel there are no easy ways to trigger actions based on external events from the Internet : for example based on in-coming mails, or on a Google Calendar. 

The Google Calendar would enable for example to control heating based on a vacation calendar. I know that you can import one in bOS, but you have to do it. It doesn't happen automatically every 3 hours or so.

The email with the right title or the right template could trigger the opening of the door, or the heating of the swimming pool, or whatever. 

That would be easy to do with IFTTT, but in the meantime, some basic features in the existing calendar or email devices would help. 

Thanks you,

François
