Does anyone know why a bunch of networked #smokeDetectors would go off when there’s no #smoke, fire, or #carbonMonoxide?

My house is pretty humid. Could that be a factor? I’ve tried vacuuming the detectors based on the theory that it might be dust inside the detector. That doesn’t seem to have done much.

Please let me know if you have a clue because this is super annoying

    Some detectors do have a problem with high humidity setting them off.

    Are you charging a lead-acid battery in the vicinity of a carbon monoxide detector? Hydrogen emitted by an overcharged battery (or one undergoing equalization) will set it off.

    It depends on what sort of tech the detectors use. Are you able to post a brand and model number. Or a photo of a sticker ? Commented Aug 19, 2023 at 0:27

    Spiders are a common issue for smoke detectors.

    If they’re interconnected, it only takes one unit to ruin your day. And these things do fail. The hardest part is finding out which one. Commented Aug 19, 2023 at 3:03
