I have a house with a fairly sophisticated alarm system using the GE Interlogix Concord 4 system. In addition to the normal sensors, it is tied into a water sensor in the basement and other ‘discrete’ inputs. Rather than pay the $30-$40/month monitoring charge, I would like to interface it to a Particle to send text messages to my phone. ‘Basement water detected’, ‘smoke detected on second floor’ or ‘garage door open’.
Has anyone handled this sort of project and have any recommendations? Judging from the number of posts about the Concord 4, and complaints about the monitoring charges, I think this could be a worthwhile project - and one that would pay for itself in a few months.
