What a “C-Bus takeover” actually involves
Not a sales word. It means reading someone else’s project, rebuilding the database, and documenting a house that nobody has documented for fifteen years.
“Can you take over the system?” is the question we get most from people who have just bought a house with C-Bus, or whose installer has retired.
It sounds simple. It is not, and it is worth knowing what you are buying.
The system remembers nothing you can read
A C-Bus installation carries a project file: every unit, every group address, every scene, every schedule. If the previous installer left it on a laptop that has since been wiped, the system still runs — but nobody knows which group address is the kitchen downlights.
The house works. The map is gone.
What we do, in order
- **Read the network.** Connect to the bus and pull the existing project off the units themselves. Most C-Bus modules still hold their own configuration, which is how a system can be recovered at all.
- **Reconcile it with reality.** Walk the house with a tablet. Press every circuit. Now we know that group 017 is not “spare”, it is the laundry.
- **Rebuild where needed.** If the database is corrupted or half-missing, we rebuild it from what the hardware is actually doing.
- **Document it.** Every room, every circuit, every scene, every schedule, in a file you own. This is the deliverable nobody else gives you.
- **Put it on your phone.** In English and Chinese, with the room names that match the house.
Why documentation is the actual product
The reason this industry has a bad name is that knowledge was held hostage. If only one person knows how your house is wired, you are not a customer — you are a captive.
We hand over the file. If you ever sell the house, the next owner gets it. If you ever want a second opinion, you can get one.
What it costs and how long it takes
For a typical 30–70 channel home, the takeover is done as part of the app-control installation: a single visit of three to five hours, from $699, plus the monthly plan if you want ongoing care.
Badly documented or partially failed systems take longer, and we quote that separately after the free check.
What we will not do
We will not replace working modules to make the job easier. We will not rename everything to our own convention so that only we can maintain it. And we will not tell you the system is obsolete when it is not — that is the behaviour that created this market in the first place.
