Temperature sensing with the Fibaro Door/Window contact

Temperature sensing with the Fibaro Door/window contact

This article will summarize sensing temperature with the Fibaro door/window contact. Temperature sensors can be used in a wide variety of applications from HVAC environmental control, chemical handling and food service industry installations. Temperature sensors tend to measure heat to ensure that a process is either; staying within a certain range or providing safe use of that application. In this example we will be monitoring the temperature of walk-in freezers.

Requirements

Fibaro Door/ Window contact – FIBFGK-*** (color)

Z-Wave controller with support for the Fibaro Door/window Contacts

Three wire temperature probe. (DS18B20)

First you will need to decide what Z-Wave controller you are using that will support the Fibaro door/window sensor (Image 1) and then of course the door/window sensor and three wire temperature probe as well. (Image 2)

We will then wire that into the input terminals on the Fibaro door/window contact. (Image 3)

Please note that you will need to wire in the temperature probe prior to adding it to your Z-Wave network.

Once you have your temperature probe wired into the door/window contact and you’ve added it to your Z-Wave controller you can then decide what you want to do with it. In this case we want the temperature in a walk-in freezer to stay between 0° - 32° Fahrenheit. So well set up some rules to basically say (When Temp probe <0° ; Then send text message) (When Temp probe > 32°; Then send text message) This will alert you when the temperature is out of range. Additionally, you can still use the door/window contact to show the status of the freezer door and set up rules to warn you when the door has been open too long.

Results

At this point you should be getting alerts when the temperature is out of range. If you are viewing the temperature and it seems to be right but your rules are not working correctly, you may need to double check the rule itself. Beyond that if you are having severe or strange issues with the door/window contact and temp sensor you should check your wiring and if all else fails then you should remove and re-add the sensor and try this setup again.
