How many Z-Wave devices can be enrolled on an account?
Z-Wave device limit
It is recommended to enroll no more than 60 total Z-Wave devices and up to 5 thermostats to ensure network stability. Z-Wave network stability depends on many factors, including the number of enrolled devices, network layout, environmental interference, and the number and types of rules and schedules being used.
The more Z-Wave devices that are in a network, the longer basic functions (e.g., network rediscoveries, etc.) may take to complete.
Note: This article provides an overview for Alarm.com's Z-Wave device limits. For more information about a panel's Z-Wave device limits, see the panel's installation guide in Panels.
Z-Wave device considerations
Thermostats
It is recommended a maximum of 5 thermostats for optimal functionality. However, Alarm.com does not prevent users from adding more than five thermostats. For Remote Temperature Sensors, there is a maximum of 10 temperature sensors on one system.
If there are more than the recommended number of Z-Wave devices, the user may experience odd behaviors or inconsistency with the Z-Wave network.
Note: For the Qolsys IQ Panel 2 with panel firmware version above 2.3.0+, up to 10 Z-Wave thermostats can be added on the system.
Locks
Locks are battery-powered and do not work as repeaters, so there cannot be a large Z-Wave network of only locks unless they were all within the range of the panel. Within practical situations, as long as signals are getting to the locks, there is not a limit on locks within the panel’s device limit.
Since all lock information is encrypted and requires more information to be sent and received, Alarm.com recommends every lock to have at least one Z-Wave repeater associated as a neighbor Z-Wave device.
