#Knx IoT
unkempt echo
Nope. I successfully got it up and runnig with two Siemens QPA2892/WI sensors. Workflow: (1) Add devices to my OpenThread Border router. (manually typing in the devices PSK) (2) They get auto discovered by my integration. Done. However, I somehow want to make it more seemless, i.e. I want to enter the PSK in my integration, preferably by scanning the QR code on the device.
Those sensors are currently only useable officially with a Siemens KNX IoT to BACnet IP router. I have that one, too, and even was able to integrate it via "Bepacom BACnet/IP Interface". But I wanted to get rid of the BACnet router.
In future, those sensors are also to be used with a KNX IoT router, which allows it to be part of a classic KNX installation. For that, ETS will need to be used.
So far, those two sensors are not in ETS.
So long story short: What I'm doing is probably not the intended way. It just uses the sensors without any KNX....

You are product manager of these devices, aren't you?

No. I am a product manager, but for a bit more boring devices 🙂 But I always like to explore ...

would they support being used "multihomed" (so provisioned both in HA and ETS ?
unkempt echo
Good question. I don't really know. I guess at some point they will add some security and that might prevent such a (non-intended) usage...

I think it's a very cool use case though. If these sensors are usable without any knx installation (which is not that common after all and has lots of additional overhead and cost)
So anyone can just shop them and use them with HA 😃

Well, if you just want a T,rH,CO2 sensor, there are cheaper ways than buying the Siemens KNX one...
But of course, we are happy for everyone who wants to use it.

Maybe... but wall mounted (EU) and properly build Thread devices aren't that common yet...

So far, my repo is private. But once it looks a bit less hacked, I am considering to put it on HACS

Nice! If you want to have anything going to the core KNX integration at some point, just ping me 😉
unkempt echo
Sure. But I am not procuding very professional code. More like a PoC type ....
The next KNX IoT end device launched will be an actuator for the old-school heating radiators, which you often see at homes.
But coming back to my original question: Any idea, if it is possible to scan a QR code during the config workflow? I've seen it e.g. in the Matter integration, but so far haven't understood how to do it myself...

Whooops: Even more expensive than I expected: 320 EUR list price in Germany: https://hit.sbt.siemens.com/RWD/app.aspx?RC=DE&lang=de&MODULE=Catalog&ACTION=ShowProduct&KEY=S55720-S552
