Add-ons in the grid view are views that display the current licensing status and installed firmware variants for controllers. There are various types of add-ons that can be purchased for controllers. Changing the installed firmware variant for BACnet or somfy add-ons a control system will enable the add-on to be used by the control system.
If you do not own an add-on for a controller you can request to purchase them by submitting a support ticket. For more information on purchasing add-ons for control systems visit How do I purchase control system upgrades.
Third party interface (TPI)
TPI is an add-on that allows other devices to override the current lighting settings. All controller products can be upgraded with this add-on. For more information visit What is the Third Party Interface (TPI).
The zencontrol BACnet implementation has been designed to expose a number of features over BACnet making integration simpler and easier. All controller products can be upgraded with this add-on. For more information visit How do I use BACnet.
LCM device limit
Lighting control modules (LCMs) have a device limit enforced for the controller. This limit can be viewed in the add-ons perspective in the grid view. To increase this limit you can purchase the upgrade for your LCM.
RS-485 application controllers can be upgraded with a somfy add-on to enable integration with the Somfy Digital Network for use with blinds, curtains etc.
A virtual switch allows for a third-party device to send switch press commands to a zencontrol switch that can be interpreted and hence used like a regular physical input device. This add-on is supported on all controller products. For more information visit What is a virtual switch/sensor.
