How Many Z-Wave Devices are Supported on the 2GIG GC3/GC3e?

A maximum of 232 unique Z-Wave devices are supported on the 2GIG GC3 and GC3e. If you try to add additional Z-Wave devices beyond this limit, then it will not work. Another important restriction is that only the first 122 Z-Wave devices paired with a GC3 or GC3e can be pushed to Alarm.com.

This automation network can include a variety of smart devices, such as smart lights, smart door locks, smart thermostats, and more. By pairing these devices with your GC3 or GC3e, you can control them directly from the panel. It is also crucial to understand that there are no sub-limits for specific types of Z-Wave devices that can be paired with a GC3 or GC3e. The only consideration for local control is the 232 device limit.

While the 232 device limit is very straightforward and simple, things become more complicated if you plan on using the system with Alarm.com for remote automation control. If you activate a 2GIG GC3 or GC3e System for monitoring service on a monitoring plan that includes access to Alarm.com for home automation, then Z-Wave devices used with the panel will also be pushed to the Alarm.com servers. This will allow you to control the Z-Wave devices remotely when you access Alarm.com via a web browser or a mobile app on your tablet or smartphone. You will also be able to include your Z-Wave devices with various Alarm.com smart scenes so that they activate automatically based on a set schedule or with certain system events.

But the Alarm.com Z-Wave device limit is lower than the 232 device limit for the GC3 and GC3 Systems. Once a single Alarm.com Security System has pushed 122 unique Z-Wave devices to the Alarm.com servers, it will stop pushing any additional Z-Wave devices to Alarm.com. In other words, Z-Wave devices numbered 123 thru 232 on a GC3 or GC3e System will only be available for local control, and they will not be pushed to Alarm.com for remote operation and inclusion with Alarm.com smart scenes. More information is available in this FAQ.

If you already have 122 existing Z-Wave devices pushed from a single 2GIG GC3 or GC3e System, and you want to use a new Z-Wave device with Alarm.com, then you must first clear an existing device from the Z-Wave network to make space. Once you have 121 or fewer Z-Wave devices paired with the panel, you can then proceed to pair a new Z-Wave device. By doing this, you will ensure that the new Z-Wave device can be pushed to Alarm.com.

Next, make sure you give Alarm.com a chance to update the Z-Wave list from your panel. This may take a few minutes. From there, you can begin adding Z-Wave devices from number 123, all the way up to number 232, if desired. But realize that Z-Wave devices numbered 123 thru 232 on the panel will not be pushed to Alarm.com, and they will only be available for local use.
