Where can I get a good GSM shield (I'm in the UK)?
I have not long moved into a new house and I'm starting to fit an alarm system.I have noticed the main panel has got a few relay outputs, including one for the alarm condition.I was hoping to be able to use an arduino with a GSM shield to send me and my girlfriend a text message if the alarm condition has activated.
There are PTS (push to set) terminals though which I might have a play with further down the line
I was thinking of something slightly different, though it might not work how I first thought. I also have one of these RFID proximity readers to fit http://www.tlc-direct.co.uk/Technical/DataSheets/Ade/TSSS01_Install.pdf they mention configuring the PTS input on the panel to accept a key switch input so I guess that would set the system? I wonder what protocol the 'comms' uses? Way out of my comprehension probably but it would be great to hack it to interface with an arduino lol.
