Had a weird false alarm on a wireless sensor in a Denver loft
I put in a new wireless door sensor at a job last Tuesday, and the homeowner called me two days later saying it kept going off. I went back and found the sensor was right next to a big metal air duct. I think the duct was blocking the signal and making the panel think the sensor was tampered with. Has anyone else run into signal problems because of metal in the walls?

Right next to a metal duct? That's a classic signal killer. I've seen metal studs mess with sensors, but a whole duct is next level. You basically built a Faraday cage around it.

How much did that set you back?
