I placed it in a ziplock bag so it would not get wet. **Q: Will I get a low temperature alert if the power is out?** A: You'll only get a notification if the power being off causes the temperature that you're monitoring to go outside of the parameters you've set. **Q: how often does this update?** A: I appears to update about once per hour. **Q: We have the Simplisafe system. Can this be used as a wireless heat sensor in the garage or attic? Not looking for a smoke/carbon, just heat.** A: SimplySafe told me that the max temp on this is 135deg. Attics can get up to 200deg. I need an attic sensor too. I’m in the south where it gets very hot. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Reduces your worries - 5 stars! *by on Reviewed in the United States January 16, 2026* Put in the well house to monitor temp while heating with small ceramic heater.
