Knowledge
Everything here is free to read, run and copy
46 worked notes, 3 read-only tools, an MCP server and 3 interfaces you can drive — none of it gated, none of it needing a conversation first. If something here means you do not have to hire anyone, it has done its job.
Start from the problem
Six situations, and where each one is answered
Nobody arrives at a knowledge base wanting a knowledge base. These are the six reasons people actually land here.
A module will not load on the version you are moving to
The stamp in the manifest is a minimum, not a pin, and the signature is a separate problem from the version.
You do not know what is actually installed on the estate
Start from the jars rather than from the drawings — then send the listing and get the per-module verdict table back.
A device does not behave the way its document says
Read the wire instead of the manual. Three read-only programs and the method for the afternoon that settles it.
Radio or broker data has to arrive in a station and be trusted
Where the payload stops being bytes, and which end of the chain owns the decode when the two disagree.
Something other than a person needs access to a live station
What the station enforces on its own, what it does not, and what that means for giving a model a write.
You would rather see an interface running than read about one
Three widgets in sandboxed frames, driven by a simulated station, with the configuration each one is reading.
Or browse
Three shelves
46 engineering notes
Narrow questions that cost a day each, in 9 groups — modules and deployment, drivers and field buses, protocols off the wire, connected devices, agents, station engineering, data and alarms, migration. Every claim checkable against a stock installation, or flagged as an opinion.
3 free tools, and an MCP server
A BACnet sweep, an MQTT tap and a LoRaWAN decoder check: one file each, standard
library only, read-only by construction. Plus obix-mcp, which
gives an agent the same read access over a station's oBIX servlet. MIT, no sign-up,
no email wall.
3 interfaces you can drive
The widgets from the interface case study, each in its own sandboxed frame against a simulated station — not a video, and not a live building. The page says which parts are real and which are simulated, in those words.
Next step
Tell us the version, the hardware, and what it has to do.
You will get a written scope and a fixed price against it. If the honest answer is that you do not need us, you will get that instead.
