Knowledge
Everything here is free to read, run and copy
54 worked notes, 14 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
Seven situations, and where each one is answered
Nobody arrives at a knowledge base wanting a knowledge base. These are the seven reasons people actually land here.
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.
Auditing a protocol claim · The fourteen free tools · Check an EDE file in the browser
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.
The artefact with the defect in it is your own site
Four things anybody can measure from outside — the redirect, the certificate, an asset still on http, a link that answers 404 — each with the fix under it.
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.
An alarm was raised and nobody was told
Three objects have to be linked, and underneath them one queue, a coalesce rule that discards a duplicate, and a recipient that can drop an alarm in silence.
The occupancy times are right on the sheet and wrong on site
Special event priority is list order, a half-covered holiday hands the rest of the day back to the week, and the next change reported is a value, not a boundary.
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.

54 engineering notes
Narrow questions that cost a day each, in 10 groups — integration and protocols; connected devices; agents and AI; the web and the pipeline; modules and deployment; drivers and field buses; station engineering; data, alarms and time; running an estate; and security and access. Every claim checkable against a stock installation, a public standard, or flagged as an opinion.
14 free tools, and an MCP server
A BACnet sweep, an MQTT tap and a LoRaWAN decoder check, plus
nine scanners that read what a Niagara installation will do
with your file: 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.
