openHAB cannot “read” data from an outside source, unless it’s its own (see persistance) :wink:

You’d have to either write a script within openHAB, that automatically updates your items, or you use an “outside” script, which uses either MQTT or the REST API to update items.

Hi Luke,
openHAB(3) aims to include more of the not so experienced users. For importing information into openHAB exist too many different use cases, which differ individually. Using clear described hardware and import their information, there’s AddOns called “bindings”; you can use the functionality of those natively within openHAB.

Importing “random” structured information from a database is so clustered, you won’t find a way to get an abstract way to import those.

We can’t help you, unless you give us a bit more context:

  • What kind of information do you store inside the database
  • What is your purpose of having some information inside openHAB
  • How is your database filled
  • do you know some kind of script language (like PHP, python, …)

perhaps we can work something out after that.

I’ve always wondered why OH doesn’t have a database layer that provides database services to the higher level features (rules, scripts, bindings, persistence).

If that existed, it would be easy to write something to query just about anything from any database.
