Smart Home Ontologies

Dear Community,

I am wondering how important are ontologies like SAREF (see for openHAB? Thanks in advance for your input to get this discussion going.

Best regards,

HABot’s ontology is based on the Brick Schema. See HABot Walkthrough (2/n): Semantic Tagging & Item Resolving. I can’t say I’m an expert in either ontologies so can’t say what the overlap is or how they might be used together, if at all. But I did want to point out that there is already a somewhat formal ontology built onto openHAB for use in HABot in addition to the informal ontology we have with our Item types.

On a first look at it, I’m not sure that I like the way they separate the technologies like that. In an OH context, wouldn’t one want to have one “Switch” instead of a zwave:BinaryPowerSwitch and a knx:DPT_Switch?

The best way to differentiate the category and property between data. Well, just wanted to start with a topic and got this. I want to open with you all, I am John and looking to explore more over here.

There is a great talk about openHAB and semantics from Kai, see
