SimpliSafe Temperature Sensor - Hot/Cold Detection - Compatible with SimpliSafe Home Security System - Latest Gen

Works perfectly well and verified accuracy to be acceptable for home use! Temperature is within 2 degrees F of a calibrated thermometer.

Our house got broken into last year on Halloween while I was home. Someone came in through the back gate and was able to get the back door open. I worked nights and slept during the day and the dogs scared them as I think they thought nobody was home. I wanted something easy to install to keep our house safe and purchased multiple cameras, sensors, and alarms. This was perfect for me to set up and feel safer in our home. Then I realized I could have multiple purposes and it could help keep my dogs safe! We have the garage turned into a large room with furniture, dog beds, heaters, and air conditioners for the dogs while we are gone but always had a fear that the temperature would get too hot or too cold, or a fire would start while we were gone and unable to help the pups. I was able to purchase a temperature sensor to keep in there to notify me of the temp reached over or under a certain amount, and several fire sensors to put up throughout the house to get immediate help in case of a fire when we are not home. This has given me so much peace of mind and so many ways. I am so happy I have purchased this system!!

Works perfect

I bought this because we had our HVAC die on us on the hottest day of the summer last year. Thankfully we got home from errands and noticed a few minutes before it actually died but it was 88 degrees in our house! Another hour or two and our kitties could have potentially gone into heat stroke.I tested this by checking that it matched my hallway AC system temp at 78. It didn’t really fluctuate at all (which is good), so I decided to test what would happen if I put in the windowsill in the afternoon sun. When it got 1 degree past my upper limit of 86, our base station went red and had beeping (lighter sound and less scary than when the entry is triggered), I also got a text alert that my hallway temp monitor had triggered. It only took about 15 mins in the window for it to go off.This gives me peace of mind in the summer so I can do outside the house stuff without worrying about my fluffy boys at home.I did not buy this for cold sensor so I can’t say anything about that, it’s the heat that I bought it for.

Seamlessly fit into my existing system.

They're temp sensors. They measure and report temperature. They work just fine.SimpliSafe is missing out on a great market opportunity with these sensors. I bought a couple extra to see if I could use them as refrigerator and freezer sensors. With lithium batteries, they measure temperatures just fine in both the fridge and deep freezer and there didn't seem to be any problem transmitting the WiFi signal through the metal skin to my router approximately 40 feet away.It works quite well in the fridge and I've got that one in operation. However, the temp sensor is unusable in the freezer because of the limitations of the SimpliSafe app. The app prevents setting the lower temperature boundary below 1° F. Since most deep freezers are set at or below that, I got constant alarms.With a simple programming change to the app, many customers could use these as freezer sensors. Of course, your mileage may vary depending on whether the WiFi signal could get through any particular fridge or freezer shell.

Ok

A great add on to the system! Peace of mind our unfinished basement remains warm in the winter.
