Thank you James for taking the time to explain. Its a shame as I run ActionTiles and quite willing to move across, but without the SHM integration it does make it more to maintain, especially as I have quite a number of sensors etc that would all need a individual rule to make it work.
Twilio sounds good and if you offered the same integration for the UK as the US I think a lot of ST users would be interested. Will have a look at the video and see if I can make it work for me.
Regards Andy
