APNT-38 - Adding the Fibaro Door/Window Sensor

Fibaro Door/Window SensorThe Fibaro Door/Window Sensor can be a little difficult to add into your Z-Wave system. This guide shows how to easily add the Sensor into any Z-Wave home automation network.

Adding the Fibaro Door/Window Sensor

The Fibaro Door/Window Sensor has two tamper (TMP) buttons; one on the bottom of the device and one inside (see figure 1).

Important: To Include the sensor into the Z-Wave network the bottom TMP button MUST be held closed (hold it closed in your fingers or mount it on a flat surface).

To Include the sensor into the network:

  • Put your Z-Wave Controller into 'Inclusion' mode and move the Sensor close (within 1m) to the controller
  • Remove the Sensor's top case and insert the battery
  • Ensure that the Sensor's bottom TMP button is closed (see figure 1)
  • Place the magnet alongside the Sensor
  • Locate the TMP button inside the sensor and press quickly 3 times
  • The Sensor's LED will flash slowly to show correct inclusion
  • If the LED flashes quickly or the Sensor is not detected by the Z-Wave Controller, wait a few seconds and then press the TMP button 3 times again
  • If this doesn't work, then 'Exclude' the device from the controller and repeat the Inclusion process
  • Note: Excluding the Sensor simply resets it, enabling it to be more easily included. Check your controller on how to do this.

You will now have the Sensor included in your network and will be able to see the sensor icon in your controller's dashboard. The same icon is used to indicate the sensor being tripped by the reed sensor's magnet being moved or the binary sensor (switch) being opened/closed (see below).

Using with the DS18B20 Temperature Sensor

To use the Door/Window Sensor with the optional DS18B20 temperature sensor, you MUST connect the DS18B20 into the Door/Window Sensor BEFORE you add the sensor into the Z-Wave Network.

The Fibaro User manual is slightly misleading where it shows how to connect the DS18B20 to the Fibaro Sensor.

To correctly connect the DS18B20:

  • Place the Door/Window Sensor on a flat surface, bottom side down
  • Position the DS18B20 with its flat face pointing down (see figure 2)
  • Connect the DS18B20's leads into the three terminals as shown in figure 2
  • Add the Sensor to the Z-Wave network as shown in the 'Adding the Door/Window Sensor'
    • If the Sensor's LED does not illuminate, the DS18B20 is connected the wrong way - check that it is connected to the correct terminals and that it has its flat face pointing down
  • The temperature will display as a second icon in the controller dashboard
  • Note:
    • The second icon may not display until the controller has finished configuring the Sensor - this will not happen until the Sensor wakes up
    • The temperature will not display until the Sensor has been polled by the controller - default set to 10800 seconds (3 hours)

Using with an External Sensor or Switch

The Door/Window Sensor can be used with an optional binary sensor or switch. Unlike the DS18B20, this can be connected anytime and does not need to be connected before 'Including' the Sensor into the network.

However, it is important to understand that the binary sensor/switch is connected in parallel with the reed sensor (magnet). If one of them is seen as closed then the Sensor will display as 'Not Tripped'. This point is worth understanding as it confuses many people when they first use the door/window sensor with an external binary sensor/switch:

  • If the magnet is close to the Sensor, this is considered closed - the binary sensor/switch will have no affect
  • The magnet must be moved away from the Sensor for the binary sensor/switch to be able to change the Sensor's status
  • By default, the binary sensor/switch is set as Normally Closed (NC) - it must open to show the Sensor as 'Tripped'
    • This can be changed to Normally Open in the Sensor's Configuration Parameter 3
  • This behaviour makes it very difficult to use the Sensor in a combined application such as a front door sensor and door bell switch

Configuring the Door/Window Sensor

When configuring the Door/Window Sensor, you should bare in mind the following points:

Only make configuration changes on the main Sensor device

The door/window sensor acts as the parent device - all configuration changes are made in the parent device and not in the temperature sensor (if fitted).

Wake-up the Door/Window Sensor

Remember that the Sensor is a battery-powered device - it will spend most of its time asleep. Like all battery-powered devices it must be awake to accept new configuration settings. The best process to update the configuration settings is:

  • Make the changes in the Z-Wave Controller
  • Save the changes in the controller so that it transfers them to the Sensor, this depends on the controller you use:
    • Fibaro Home Center 2 click 'Save'
    • Zipato - click 'Synchronize'
    • VERA - go to Settings and click 'Configure node right now'
  • Then quickly press the Sensor's internal TMP button 3 times - the Sensor's LED will flash slowly and the device will stay awake for 5-10 seconds


The Door/Window sensor reports different information to different Association Groups.

  • Group 1 - alerts sent from IN1 (magnetic sensor and external sensor/switch)
  • Group 2 - alerts sent from the TMP switches

Note: Most controllers will only use Group 1 to indicate triggering of the device, this means in most cases only the IN1 (magnetic switch and external switch) can be used in scenes and notifications. To receive alerts from the TMP switch, you need to associate another Z-Wave device to the Sensor's Group 2.
