VI er netop nu igang med at udvikle en ny App til Homey Pro. Det betyder at vores produkter vil virke bedre end nogensinde før. Hold øje med vores facebook side, her vil vi poste et opslag når den er klar.

When starting up a new HomeCenter 3 from Fibaro, you will be given the choice between using Engine 2 or Engine 3 Beta. We recommend that you choose Engine 2, as Engine 3 is still a Beta version with a number of bugs that can cause challenges with some of our products and 3rd party products. 

If you are experiencing problems and you have selected Engine 3 Beta, reset your HomeCenter 3 and start it up in Engine 2, after which the challenges should be gone. Note that you will lose all your programming by resetting. However, this is the only option right now. 

You can buy Logic Group products through our resellers or as part of a Smart Living package (see FAQ on this).

See the list of dealers here.

Yes, it might be. If you're replacing an existing installation, it's actually legal. Just remember to turn off the power and follow the instructions!

Advice and guidance from the Danish Safety Technology Authority can downloaded here.

However, if you need a new installation, you'll need a licensed electrician.

All our products are CE marked and meet the applicable requirements of DS/EN standards and directives. See the technical data for each product.

As a member of the Z-Wave Alliance, our products are also Z-Wave certified according to the Z-Wave Alliance requirements. This means you can use our products in seamless connection with other Z-Wave products.

Our products have S0 Security, S2 Security or both and are thus protected against hacker attacks.

According to the Danish Sale of Goods Act, you have a 2-year warranty. The warranty covers all defects that were present or where the cause of the defect was present when you received the goods.

Update program

With our Firmware Loader Common, you can update all types of devices from Logic Group.

Follow our guide to firmware update with Firmware Loader Common.

It will log the device out of your smart home and you will have to log it back in afterwards. All setup will be deleted and you will have to do it all over again.

As written, it requires a Z-Wave USB adapter.

PC Controller 5

With the same Z-Wave USB adapter, you can also download and install the Silabs PC Controller 5.

Follow our guide to firmware update with PC Controller 5 here.

If you follow the instructions, you can include the Z-Wave USB adapter and firmware update your devices without them being announced. This way your programming will not be lost.

We can do it

Alternatively, you are of course welcome to send them to us and we will do it all for you. Your devices will be notified in connection with the update and testing.

Alternatively, we can come to you and do it on your premises. This way you don't lose your programming.

This will be billed as an hourly rate for full hours started.

Take a look at the manual on page 27, parameter 18 (key 1) and parameters 26, 34 and 42 for keys 2 - 4.

Here you can set the level at which this button should turn on the light.

Default is 255 in byte 2 = last level the dimmer has been on, but you can also set it to a value between 1 and 100 = level in %.

The value you need to set in parameter 18 is calculated from Byte1, 2, 3 and 4 as follows.

Byte1*256*256*256*256 + Byte2*256*256*256 + Byte3*256 + Byte4

Example. With power on at 100%

1*256*256*256 + 100*256*256 + 0*256 + 0 = 23.330.816

You can also use the downloadable calculator below.

Remember it must be set for all keys that need to turn on a light source at that level.

This allows for different ignition levels for the individual keys.

Single and Multichannel

Devices that only have one function must be bound as single-channel (Dimmy, Wall Plug and the like) (Dimmy in particular has a firmware update that makes it a multichannel device, which is particularly useful in Home Center 3)

Devices with many functions must be bound as Multichannel (MATRIX Control Touch and similar)

Endpoints and Groups

In MATRIX Control Touch with dimmer (ZDB5100), Endpoints 1-4 correspond to buttons 1-4, Endpoint 5 is the internal dimmer. Endpoint 0 is the root device

When making associations between devices, you need to use association groups. MATRIX Push Button with dimmer has 14 association groups: 1 for the root device, 3 for each button and 1 for the dimmer. For each button (1-4) there are three groups:

  • Basic report: sends a report on the status of e.g. a dimmer, whether it is on, off and level. To be used in correspondence setup.
  • Binary Switch Set: For relays - sends a message for the device to turn on or off (MATRIX Push Button with relay, MATRIX Socket, Wall Plug and similar)
  • Multi-Level Switch: For dimmers - sends notification of dimmer control (MATRIX Control Touch with dimmer, Dimmy dimmer and similar)

To make things a bit more complicated, there are two ways of numbering: from one end from 1-14 or with numbering for each Endpoint starting from 2-4 (the 1s are used by the controller to update its interface)

For example, to associate a MATRIX Control Push Button to a Wall Plug, you need to use single channel and group 3 (or 6, 9, 12 for buttons 2-4) which is Binary Switch Set, i.e. the on/off command.

If your light source is blinking, try the following: start with step 1 - this works almost every time! Move on to steps 2 and 3 if the previous step doesn't work.


Try setting parameter 4 to value = 2

This sets the dimmer in the Matrix to low edge dimming.

Default is parameter 4, value = 1 which is trailing edge dimming.



It sounds trivial - but try unscrewing and reinserting the light source.



Try updating the firmware in your Matrix ZDB. There is a new version that takes into account noisy 230V supply. See the FAQ How do I firmware update my devices?

To find the Firmware version in Fibaro Home Center 3: click on the cogwheel -> Devices -> Click on the "down arrow" next to the device you want to see the firmware version for -> Version: xx

You can have a Smart Living smart home whether you build with Milton, Hybel, Lind and Risør, HusCompagniet or a completely different builder.

The process is typical:

  1. The first dialog goes through your construction advisor.
  2. You'll go through the options - for example, it's possible to book a viewing in HusCompagniet's test house at Lundbjerggaard in Vindinge near Roskilde.
  3. Once you have your electrical plan ready, simply send it to one of our Smart Home specialists at Logicliving@logic-group.com. They will create a proposal for you, which of course can be modified until you are satisfied.
  4. Now we start integrating the solution into your house.
  5. When the house is almost completely finished, the electrician will come and install your smart home components. It takes about a couple of hours and leaves no trace, other than a smart home 😊.

Our current solution is designed to control all windows in the VELUX INTEGRA series.

The solution consists of our VELUX 1G and a Sensative Strip switch for the window.

With our solution, you copy the VELUX remote control into the Matrix control print. This means you can open and close the windows and open the ventilation damper.

It is possible to report the window directly into our solution, even if the remote control is broken or lost.

One VELUX 1G provides one control for e.g. windows or curtains. You have the option to register multiple windows on the same module from us. This way, all of them in the group will be activated when you control them from our solution.

Later on, we will come up with a solution where all windows can be controlled separately and you can see if the window is open (VELUX 200G).

You can also enroll curtains and other devices, like awnings, regular curtains, as long as they run io-homecontrol.

Yes, but you need firmware version 1.12. Find the ZHC5010 in the firmware section and open "older firmware versions".

Similarly, the manual for version 1.12 can be downloaded from the manual section.

Make sure you have associated endpoint 0 to group 1 in Home Center as Multichannel.

Then the status will automatically update in the Home Center.

Logic Group creates integrated smart home solutions where everything is programmed from the start. This means that we have designed a solution based on an electrical plan from the customer and integrated according to agreement.



We use a Fibaro Home Center 3 as a controller.

Our choice of controller is based on an assessment of security, localized functionality, support for the protocol standard, compatibility with current and future Z-Wave Plus products and a number of other factors.



We have the following products integrated as standard:

- Z-Wave devices

- VELUX windows

- Curtains on Z-Wave, PowerView or io-homecontrol (the new SOMFY protocol)


- Philips Hue via Bridge

- IKEA Wireless via Philips Hue Bridge

- Many different IP cameras

- Google Home / Home Assistant

No, we only have white keys, as this allows light to pass through.

Our products run on Z-Wave Plus. Philips HUE components run ZigBee Light Link. How can this be compatible?

In our solutions, we use a FIBARO Home Center 3 together with a Philips HUE Bridge. These two devices are connected via computer networks on Ethernet, either wired or wireless and via communication on IP addresses. The Home Center 3 communicates via HUE's Bridge with the HUE devices and all devices on the Z-Wave Plus network can help control HUE's smart lights. HUE is not a complete smart home solution - it's smart lighting. We call this a 3rd party integration.

There is no magic involved in this, we simply use the proprietary interface that Philips makes available on their Bridge on an IP address. The basic part of the software used in Home Center 3 is done by FIBARO, so Logic Group just reuses some tried and tested software that already exists, and then we add a few things ourselves.
Ideally we would like to use an open standard, but it doesn't exist yet, maybe one day something called CHIP (Connected Home over IP) now MATTER will come along and solve this challenge. It has just been released in a version 1.0 and is not very comprehensive yet. Philips is on board with this and has opened up Matter in their Bridge.
See also Anders Frederiksen's guide to adding Philips HUE to Home Center 2.
Home Center 3 also has the option to enroll ZigBee devices directly.
This allows you to do without the ZigBee bridge and control the devices directly via ZigBee.
We have developed a QuickApp + a Lua scene to connect a button to a ZigBee device so that it can do the same as with a regular light source, controlled by the internal dimmer.

No, there is absolutely no room for electronics in a 1-module outlet when safety distances to live parts must be maintained.

That's why you can only get 1½ module MATRIX Sockets from Logic Group.

Unfortunately, SmartThings is a little tricky to develop for.

Samsung has chosen to make a controller that may have Z-Wave, but does not comply with the standard for a Z-Wave controller. If it did, all Z-Wave Plus devices would automatically work with it.

They have chosen to create their own way of using 'Z-Wave', which removes many of the good ideas in Z-Wave.

One of the challenges is that you have to develop drivers for all the products you want to work with their way of doing things.

As a counterpart, there are a number of controllers that are certified Z-Wave controllers, such as the Fibaro Home Center 3 (HC3), which we usually recommend.

When a new Z-Wave Plus device is developed, you simply enroll it in HC3 and it works. HC3 is also backwards compatible with old Z-Wave devices.

Another challenge with SmartThings is that they don't support Associations, where the devices bind directly to each other so they can communicate without the use of WiFi or a controller. This ensures that your house is less vulnerable if, for example, SmartThings or the router is down.

Unfortunately, there are a number of controllers that do what SmartThings does. Examples include Homey, Home Assistant, OpenHAB and Homeseer.

All of these require specially developed integrations, all of which do so in their own way.

With the resources we have available right now, we can't develop all of these.


That said, we have actually developed an integration to Homey and SmartThings for our Matrix range.

Homey is released, but SmartThings would not approve our driver as they had just released their new SDK.

Now we can start all over again, towards their new SDK. It's coming, but we don't know when we can allocate resources to develop version 2 for SmartThings.
