It send an email when circuits changes from open/closed. I'd like to monitor three circuits at least.
Checking the circuits once every few second is plenty fast.
The black box should be robust, and cheap. It only needs to send emails, not receive.
My ISP is Voyager. For email, they use
* an IMAP server,
* that uses authentication
* non-default ports
So the email client is a little complex. Anyone have suggestions?
My research has found these
Raspberry Pi and PiFace
Not sure if these will work though.
