A Group Association is a specific function in Z-Wave that allows you to tell the TriSensor who it can speak to. Some
devices may only have 1 group association meant for the gateway, or multiple group associations that can be used for
specific events. This type of function isn't used too often, but when it is available, you may be able to use it to directly
communicate to Z-Wave devices instead of controlling a scene within a gateway which can have unforeseen delays.
Vera has the ability to set Group Associations to devices that have these special events and functions. In TriSensor
case, it can speak directly to the devices it is associated to for directly toggling On/Off controls via temperature or
motion sensor triggers without communicating to your gateway.
For example:
Using Group associations will talk directly to a Z-Wave device, this will process less than 1 second usually within
10-100ms.
Triggering a scene, a device will need to update its status to your gateway, then have the gateway process the
status update then send an action or change to a Z-Wave device based on the trigger. Sometimes there may be
delays if your gateway is already processing other data which can cause 1-2 second delays from time to time.
How many devices you can control.
You can control 5 devices per Group Association for a total of 10 separate devices per button over 2 different Group
Associations
Example;
5 devices on Group 2 (motion sensor control)
5 devices on Group 3 (temperature sensor control)
How do I control my devices using group association?
This is a bit difficult as many gateways provide this function and just as many gateways will not provide an option to
program this. You'll need to look into your gateways functions and see if they support "Group Association" and how to
do it.
5. Enable or disable Group 2 or 3 group association for direct control.
This parameter is configured the enabled or disabled send BASIC_SET command to nodes that associated in group
2 and group 3.
