HowTo to tag

i ran openhab several years with untached itemm files. now i moved to latest openhab version cam somebody point me to a howto for tags or antother good ressource for what how they are used ?

is it just used to define a device type ?

thanks in advance


So basically the question is, do you have a specific need for tags? If yes, then the documentation of the add-on/system for which you need the tags will explain which tags are used for what purpose.
If no, then there is no need to start using them.


If you e.g. want use one of the following, then you need tags:

hueemulation in combination with Alexa


OpenHAB Cloud in combination with Amazon Alexa Skill or Google Assistant

thanks a lot!
