I’ve got two of these I want to use with pressure pads. I built a cardboard and foil pad based on an instructibles project, works great for my bike in the garage. The sensor worked ok for a few hours of testing, then simply stopped responding. I used some garage door opener “eye” wire I had left over, a few feet of it. When I removed the pad and just touch the wire ends together, no actuation. Removed the wire and just used a paper click between the two contact block sides, nothing. Magnetic sensor still triggers it as does the same wire shorted over the reed switch contacts. Like the sensor block died??? Tried a second so far unused sensor, and it didn’t register either. The tamper alert works for both, so I know it’s reporting to ST.
Any thoughts? What “things” and wire are folks using for these external contacts? Also, the instructions say normally closed contacts should be used, what’s the diff really if normally open like the pressure pad is used? Battery drain maybe? I can easily wire a 2xAA battery module to this, so not worried about that.
