Your .knxproj already knows what is wrong. Nothing has read it.
Drop the project file in. You get back what the installation is actually doing — the parameters inside the devices, the automation already running on the bus, and the defects nobody wrote down.
Free, permanently. No card. You do not talk to anyone unless you want to.

Disclosure. 191 Tryon Rd is The author's own house. It is the only installation we have analysed in full, and we would rather say so than imply a client base we do not have.
Where the bus stops
Not because KNX is limited — because a device acts on what it alone can sense. That is a wiring fact, not an opinion about one system being better than another.
A device decides this on its own
- —Presence in the room it is in
- —Lux at its own sensor
- —A staircase timer it holds itself
- —A scene it was told to store
These need two systems at once
- ×Occupancy across rooms
- ×A tariff
- ×A forecast
- ×A calendar
- ×A person's phone
This is for a specific person
You commission four or more KNX projects a year.
You get asked to connect KNX to a control system — an app, Home Assistant, a visualisation — and it is painful every time.
You have a project attached right now, not a general interest.
Twenty-five projects a year with no integration work is not a problem we solve. If that is you, we are probably not what you need yet — and the check stays free regardless, so run it anyway if you are curious.
Drop your .knxproj in and see what it says about your project.
Not a demo. Not a call. The file goes in, the findings come out, and you decide whether any of it is worth a conversation.
