I had SimpliSafe for a while and the batteries last a long time (3 1/2 years, no battery change for me in any sensor) -- but the base station, even after a reset, still seems to know when a door sensor is open or closed. I had thought about using the IRQ pin on the radio to wake up the node when a status request was sent, but most people here were saying this is terrible for battery life. How the heck is SimpliSafe keeping batteries lasting for almost 4 years (and maybe longer) but still retain the functionality of detecting what state a sensor is in?
Is it maybe that they have the sensors wake up and report every minute or something? I thought about doing that, 1 second of every 60 seconds powered up shouldn't have too much battery impact, should it?
