Z-Wave Entity Naming

Binary Sensor

Devices that support the Binary Sensor command class will create one (or more) entities starting with binary_sensor. For example, if the node is door_sensor then the binary sensor entity will be binary_sensor.door_sensor.

These will normally be on when the sensor is active, otherwise they will be off. Some devices use on for closed, and some use on for open, and some devices allow you to change how they report.

Alarm

This is for a single purpose sensor, multi sensors are explained under Multi Sensor.

Devices (usually sensors) that support the Alarm command class will create entities starting with sensor, and with some generic suffixes, and a suffix that relates to the supported alarm class. For example, the smoke detector lounge will have an entity sensor.lounge_smoke, and possibly also sensor.lounge_alarm_type and sensor.lounge_alarm_level. If the device creates a binary_sensor entity, it is recommended to use that rather then the sensor entity.

Note that the older Z-Wave alarm command class version 1 didn’t have standardized types, and so each manufacturer specified their own version and type info. With Version 2 the alarm type was standardized to the below list. See the openzwave alarm command class documents for more info. You can see which version your sensor supports via the zwcfg_0x*.xml file. An example with version 2 support:
