Have had a ST network up for years. This particular sensor turns on the light when you enter the room and has been in place for 4-5 years. Recently it began sensing motion events at very regular intervals, 13 minutes apart to be precise. Spooky. Changed the battery, same thing. Pulled out another sensor, same thing. 13 minutes between each alarm? Um, time to move, right?
That being said, downloaded the logs off the device and it averages 12:33 between false triggers. Nothing new has gone into the room, except quite honestly, a keepsake from my grandfather that my dad recently passed on to me. In the interest of science, I have moved it out of the room, still getting the events. Heh. Even put in a sensor from another part of the house that was working fine but it picked up the events as well. It did not however detect events in the new room the keepsake was moved to, again, in the interest of science. No other motion sensor in the house is detecting events except the ones in this room that, on the average when you round up, sense it every 13 minutes. Creepy… I even put two sensors in the room, one facing out to the room as normal and another on the desk, turned around with the motion sensor covered to prevent firing. Only the one facing the room fired, so it has to be SOME kind of motion that thing is sensing, right?? Next step is IR cameras at night, not sure I want to see that footage. My wife told me ‘You guys have fun up there’ when I told her about it. LOL
What, besides Pazuzu or Gozer, would cause this? I’ve unplugged all devices/electronics in the room except the modem and router, kind of need those and they are there for the long haul, cannot move them without a real PITA. Literally everything else is off and unplugged. Even the lamps. I’ve take the picture frames off the walls in case some kind of RF signal was bouncing off of it.
I cannot figure out exactly when it started happening, but nothing significant has been changed/added/ turned on in the last month or so, except of course, the keepsake from my grandfather, an antique collectible whiskey decanter from 1972 celebrating USC winning the national title in football. Nothing too nefarious there, is there?
