What is the FidBox?














The fidbox® is a monitor for temperature (°C) and relative humidity (%) as well as a data log for long-term data recording all in one, which is concealed in the hardwood flooring itself. The data stored therein can be read at any time by wireless transmission and allows the determination of the degree of moisture in the screed and in the hardwood flooring by vertical measurements. This information is not only pertaining to the indoor environment, but is especially important in the event of damage as it provides understandable facts.

For example, if damage occurs to the floor due to excessive floor temperature in the hardwood or through increasing or decreasing of moisture, often a lengthy fundamental research as to cause is needed and this might result in unjust blame.  The fidbox® puts a stop to that and provides unadulteratable clarity as to the question of guilt; prompt – candid - definite! 

The fidbox® brings measurable benefits to the hardwood installer, designers, owners, occupants or builders. The results of the measurements can quickly clarify damage claims and thus speed up the process of clarification and solution.
The fidbox® is a product that is directed at resolving a genuine problem and it offers a lot of extra security on top. The relevance of this subject itself is apparent, as many damage claims can eventually endanger the pure existence of many hardwood installation companies. The fidbox® provides unadulteratable results that are recognized by hardwood flooring inspectors and therefore an important element in the preparation of a court case.


Thanks to the fidbox® App, you have the ability to control your room climatic condition in the areas the fidbox® has been installed.  When measured values, which are evaluated using a trend analysis, reach a “critical” value, you are actively warned and get suggestions on what measures are necessary to prevent possible damage, and help you return to a healthy indoor climate.


Temperature in underfloor heating too high – please lower the temperature.
Room temperature too low – please activate the heating.
Room humidity is too moist – please ventilate.
Room humidity is to dry – please humidify.


Negative room climatic conditions are an eventual risk to health; by using the App, you have the possibility of an active monitoring for a healthy room climate.

nstallation fidbox®


Choose the optimal location for the fidbox® together with the builder or architect before installation. The fidbox® should be integrated into rooms with the highest room climate variability, for example, in the middle of the room or above areas of underfloor heating.


A minimum of one fidbox® should be planned for each room with a size greater than 30 m² of floor space at a distribution of one per 50 m² of total wood floor area. In multi-story buildings and/or rooms with multiple heating circuits there should be at least one fidbox® per floor or heating circuit.


Please Observe: (reading errors may occur by non-observance)

No furniture should be placed over or on the position of the fidbox®

Do not lay textile rugs over the position of the fidbox®

Avoid strong magnetic fields on or above the fidbox®



Store the fidbox®, dry and frost-proof at room temperature (+17°C to + 23°C)

Safeguard the fidbox® in the supplied storage box until ready for use.

Never subject the unprotected fidbox® to direct sunlight or submerge in water.

Do not crack or bend. Never drill or saw through the fidbox®.

Do not store the fidbox® near magnetic fields.


In case of loss of battery power the stored data remains intact for many years after power loss and can be recovered.  In this case contact us.


Step by step




1st step

The fidbox® should be installed into the wood floor directly under the top layer.

Attention: please note that at least 3 mm of the top layer must remain. Otherwise a crack in the hardwood element can occur.

It is necessary to mill out the necessary recess in the wood floor in the required dimensions (l x w x d) of the fidbox® 9.5 x 5.3 x 0.8cm (in addition to a min. 8 mm the hardwood panel edge) with the aid of a template. This can be accomplished professionally using a router or with the use of suitable tools.



2nd step

During the wood floor installation the cover of the adhesive strips which is applied to one side of the fidbox® is peeled off and the fidbox® is then fixed with this side being inserted into the wood floor piece. Use no other adhesive or sealants as they can under certain circumstances endanger the flawless function of the fidbox®.



3rd step

During wood floor installation you insert the prepared wood floor piece at the pre-determined position. Avoid the contact of wood floor adhesive to the underside of the fidbox® which is the point (see blue circle above) of measurement as it might cause inaccurate measurement readings. It is best to leave this area near the sensor free of adhesive. Solvent based artificial resin adhesive should not be used as it may also cause inaccurate measurements.



4th step

After the wood floor installation is finished, note the exact position of the fidbox® in the “fidbox® Installation Record” and enter all general information concerning this particular project. These records will facilitate the prompt locating of the fidbox® and simplified data recovery.  A simplified sketch with dimensions should be prepared and a copy given to your customer.  This information will be needed for logging into the fidbox® App.
