For what can I use tags?

I’m pretty new, but I fell in Love with openHAB =D

I don’t really get the usecase for Tags. I know that I have to Tag my Switches with [“Lighting”] that my Alexa can find them, but yeah thats it. And why Alexa needs a Lighting Tag?

Can I use own custom Tags or is anywhere a List of predefined Tags?


Tags are needed by the Alexa Skill and a couple of other addons (Hue Bridge and HomeKit I think are other ones I think). You will have to read the readmes for those to find out the when and how of using them. I don’t know myself, never used tags. But at a high level, tags are used to tell the bindings to expose those Items to the external service.
