### ⭐⭐⭐⭐ 4.0 out of 5 stars







  
  
    Works great but costly batteries and high temperature alarm limitation
  

*by M***. on Reviewed in the United States on June 4, 2018*

Using 2 of these as door and temperature sensor for my fridge and freezer.With the reporting set at a meaningful level (every 5 minutes, 1 degree Celsius increments) to make sure that the temperature doesn't go into the danger zone too long, the battery of this device only lasted about 6 months. With a low battery the reporting sometimes won't transmit, even for the basic door sensor.I guess you could reduce the sensitivity even further and rely more on the alarm thresholds but I prefer gathering the raw data. Also, the high temperature alarm is useless for a freezer as the lowest it can be set at is 0 celcius (32 Fahrenheit).Instead of buying a new set of batteries (cheapest I could find was $10 for 4), I hard wired them to a 3.6V charger (B0108STRZM for $12) and I'm not worried about the batteries running out anymore! I could even increase the reporting sensitivity.

    Great Temperature Sensor, Works With Vera
  

*by P***E on Reviewed in the United States on August 30, 2018*

I've had a couple of these operating with my Vera Secure for about 6 months now.  One is inside my freezer, and one outside on my water feature.The one in the freezer amazed me in that, despite being surrounded by metal except for the door seals, it still reliably gets a signal out to my controller. (Yes, I have the whole sensor in there, not just the probe!)  I was wondering how the battery would do in the cold.  It dropped from 100% to about 80% right after going in, but it has been working for 6 months now and is reporting 66%.  I have it set to measure temperature every 5 minutes, and send out a report for temperature changes of 0.3°C (~0.5°F).I have a second one outdoors with a DROK submersible temperature probe in the water of my water feature.  I use it to monitor when the water temperature gets near freezing in the winter.  On the flip side, it endured the 110°F temperatures of Arizona summer with no problem.  (Yes, it goes below freezing at my house, too!)The only negative I have with these is the battery.  I have dozens of other sensors around the house that all use CR123's.  This one uses a 14250, which is sold through fewer sources and it forces me to keep another type of battery around.

    Z-Wave Plus Version (firmware 3.2) does not work with SmartThings
  

*by M***L on Reviewed in the United States on August 3, 2017*

I did actually receive the Z-Wave Plus version of the sensor (firmware 3.2).  I was able to add it to SmartThings. BUT, SmartThings does not see it as an open/close sensor. In fact, SmartThings does not indicate any status whether sensor opened or closed.Really wanted this sensor to work since it is smaller that most other door/window sensors.Device also uses a somewhat expensive battery ER14250 3.6V (1/2AA). I have never heard of any device here in the USA that uses this strange battery.Oh well, I guess I go with the  Ecolink Door/Window Z-Wave Plus Sensor DW-ZWAVE2.5 which seems to be working OK without issue.  The Ecolink is humongous compared to the Fibaro.
