ZWAVE ALARM CLASS -- 过时的sensor告警和事件上报机制_zwave 协议如何配置上报-优快云博客

本文介绍了ZWAVE协议中报警和事件上报的机制，从老式的Alarm Command Class到新版本的Notification Command Class的转变。Alarm Class在旧设备中用于报告报警和服务状况，但其参数非标准化，而在新版本中，Notification Class提供了更规范的告警报告，提升了设备间的互通性。同时，文章提到了设备如何选择支持的命令类，以及在控制和被控制设备之间的差异。

Sensors may bedesigned for two purposes: A multilevel sensor advertises a measurement. Anotification sensor advertises a specific event. Legacy notification sensorsmay implement the Alarm Command Class. 老的sensor可能实现的是Alarm Command Class。

A notificationsensor may be designed to operate in push or pull mode. notification sensor可能工作在push或者pull模式中。

A push modenotification sensor sends unsolicited notification reports. The transmission ofunsolicited notification reports may be disabled or enabled via theNotification Set message. Even if enabled, unsolicited notification reports canonly be transmitted if an association destination is defined. Pushfunctionality such as event reporting via Notification CC and relay control viaBasic CC are advertised via the Association Group Information (AGI) CC. 支持push模式的sensor会主动上报事件。可以通过Notification Set message来控制“使能”或者“停止”sensor主动发送事件。不过即便是使能了sensor主动发送事件，也只有在指定了association destination（通过association命令）时，sensor才会主动发送事
