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 10 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.
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. 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 to have a maximum of 10 thermostats for optimal functionality. However, Alarm.com does not prevent users from adding more than 10 thermostats. For Remote Temperature Sensors, there is also a maximum of 10 temperature sensors on one system.
Note: Some IQ panels can set Z-Wave device limits to a higher number, but it is still recommended to add no more than 10 thermostats to ensure network stability.
Locks
Locks are battery-powered and do not act as repeaters, so there cannot be a large Z-Wave network of only locks unless they are all within the panel's range. Within practical situations, as long as signals are getting to the locks, there is no limit on the number of 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.
