What Versions Do I Have Node Red Installed?

Before you update Node-RED, npm, or Node.js, you might want to see what versions are installed. This is pretty easy to accomplish from the command line.

node -v
node-red --h

ha 资深玩家，到最后都只是通过ha接入，nodered整合，简化到 homekit。不说别的，一个五口插排，只有通过 nodered 才能显示成一个具有五口的设备，ha的话会显示成单独的五个开关。折腾留给自己，最纯粹的 homekit 体验给家人。

我都是接入 ha 后通过 nodered 定义设备。你说的那个滤网寿命之类的是可以接入 homekit 的，定义 air Purifier 是附加一个 Filter，可以组合成一个全功能空气净化器。
