  • Modify $15 SimpliSafe entry sensor as a wired switch

    Great instructions. Wanted to add that I was able to do this with sensors bought this week without removing the circuit board and battery connectors. I used a soldering iron to poke a whole through the plastic sensor and ran the wires through there and to the side of the battery. I cut the wires staggered so there was no excess and looped and soldered them. So far so good on 4 wireless units monitoring 13 windows and a pair of French Doors. I used wireless sensors on the three main doors and 4 critical windows however I might go back and swap these to the pre-wired and use the extra sensors to monitor the upstairs. I wish Simplisafe would either build this in or offer a multi sensor with a 4 zone block on it.
