如何使用 z-wave 获取 node-red 中的门锁状态
How to get the status of door lock in node-red using z-wave
我已经尝试了各种不同的主题和参数来尝试让 z-wave return 我的门锁状态。我可以打开和关闭锁没问题。我的问题是当 Node red 重新启动时，它不知道锁定状态的状态。
我找到了答案并想分享它。这是节点的导出：

您会注意到值已更改和扫描完成的两个节点都有输出。在这里，您可以通过读取流变量 "nodes" 来定向到一个函数，以从 z 波节点中提取您想要的任何信息。比如我获取电池电量和锁状态如下：
var nodes = flow.get("nodes");
var node = nodes.find(n => n.nodeid == "2");
var value = node.values.find(v => v.value_id == "2-128-1-0");
var batLevel = value.value + "%";
value = node.values.find(v => v.value_id == "2-98-1-0");
var lockState = value.value;
return [{payload: batLevel}, {payload: {"nodeid": 2, "cmdclass": 98, "value": lockState}}];
这将 return batLevel 通过一个输出和一个 json 到锁定开关，该开关用于在更改开关时触发锁定（我禁用直通并仅使用它来更改开关）。
