How can I retrieve the Mac Address of my device?

  1. If your device is already configured and connected, then simply log in to the Web app with your credentials. Once logged in, on the ‘Device’ page you will find the Mac Address in the first column (Conn ID).
  2. If the device is not yet configured, then you will need to connect the device to the power supply. When first switched on (or once reset), the device will generate the SmartSensor-MAC network (= Mac Address of the WiFi module WiFi).

I can not configure my device, what could be the cause?

  1. Check that your smartphone is connected to the Internet.
  2. Check that the WiFi network is working properly and that it operates at a frequency of 2.4 GHz.
  3. Check that the password entered is correct. If not, reset the device and repeat the installation procedure.
  4. Check that there is no firewall (protection) on your network preventing your device from connecting.
  5. In this case, you must enter the Mac Address in the list of devices that can connect to your network; this procedure depends on your WiFi network manager. For this point, see how to retrieve the Mac Address of your device in the appropriate section.
  6. From your router, check that port 1884 is open. This can usually be done in the port mapping section, check if you can indicate Telnet Server.
    If you have not solved the problem, please contact technical support ( indicating the unique code on the back of your device.

I need to change the credentials of the WiFi to which the device connects, what should I do?

In this case, follow the procedure indicated in the appropriate section of the manual. In summary, you must reset the device and redo the configuration.

The device does not switch on, what could be the cause?

  1. Check that the plug is inserted correctly into the socket.
  2. Check that the micro-USB cable is correctly inserted into the device.
  3. Try using another adapter and/or cable. If this solves the problem, contact the service department for pick-up and delivery of a new power adapter.
  4. If this does not solve the problem, please contact technical support ( quoting the unique code on the back of the device.


Which comfort temperatures should I set?

The best comfort temperatures are those set as set points in your heating and cooling system (if present). Fybra Home has no power to act directly on the increase (in winter) or decrease (in summer) of temperature, but thanks to its algorithm it will calculate the window opening times to ensure that the temperature set on your air conditioning system is respected and the air quality remains within the comfort range.

Why is it important to enter the position?

Fybra Home uses external climate data in its algorithm, so the correct entry of the city where the device is installed is necessary for the algorithm to be effective.

Why do I sometimes find my device switched off?

Fybra Home has a switch-off threshold of 500 ppm below which the device switches off the visual signalling. This mode is designed to reduce power consumption by deactivating visual signalling when nobody is around, even though data monitoring is continuous.

Why is my device always red? What are the causes?

  1. If you are not used to opening the window very often, the first period with Fybra Home may give you the impression of frequent opening. Don’t worry, it’s just a matter of habit!
  2. If the openings are too prolonged or inefficient, it is possible that a constant pollutant source (VOC) is present and that the air exchange is not sufficient. In this case, it is advisable to try out different positions of the device in order to demarcate the polluted area and identify the source.
  3. If the openings are too prologed or inefficient, check that the device is working properly. Try placing your device near an open window or outside and see if you get a lowering of CO2 (<500) and VOC.

If you still have doubts, please contact technical support (

Does the device work right away?

The sensor needs a maximum of two weeks of adaptation, both for settling the measurements, through the self-calibration algorithm, and for the dynamic algorithm to come up to speed.
