This application note explains how to use the secondary (S2) switch input of the Fibaro Dimmer 2 modules to directly control other Associated Z-Wave devices.
The Fibaro modules have two switch inputs. S1 is used to control the local load physically connected to the module, while S2 can be used to control the local load as well as other Z-Wave devices:
This feature makes the Fibaro modules very versatile and yet easy to configure.
By using the secondary (S2) switch input of a Fibaro Module you can easily control other Z-Wave devices.
The following shows a simplified diagram where a Fibaro Dimmer 2 is able to control a number of Z-Wave devices Including other Fibaro modules, wall plugs and dimmer sockets.
Note: Connections for the local load are not shown in the above diagram - the Fibaro Dimmer 2 must be connected to a local load!
Once you have wired the modules into your installation, you need to Associate the Fibaro Dimmer 2 module to other Z-Wave device or devices.
Note: For step-by-step instructions on how to create Associations between both devices follow Application Note 19 - Associating Devices in Z-Wave Controllers.
The Fibaro Dimmer 2 has 4 Association Groups to choose from depending on the device type you are controlling:
Some parameters can be set to configure how the device sends commands to each Association Group.
This determines which value is sent to Associated devices on single click.
Available settings are:
This determines which actions will not be sent to Association Groups 2 and 3.
Available settings are:
Values can be combined. For example if you don’t want to send command frames when switching On and Off Parameter 24 should be set to 3 (1 + 2)
This determines which action will not be sent to Association Groups 4 and 5.
Available settings are:
Values can be combined. For example if you don’t want to send command frames when switching On and Off Parameter 25 should be set to 3 (1 + 2)
This is probably the most important Parameter to take into consideration when dealing with Associations - it determines if commands are sent as secure or non-secure on Groups 2 to 5.
If the Fibaro Dimmer 2 was Included in security mode it will try to communicate with other Associated devices in secure mode only. However if you are creating an Association with a device that doesn’t support secure Associations – or a device that was Included in non-secure mode – you may need to configure the Fibaro Dimmer 2 to take this into account.
Available settings are:
Again values can be combined. For example if you only need Group 2 to be sent as non-secure Parameter 27 should be set to 14 (2+4+8)
