Hardware is quoted per unit and compared per unit. Commissioning is quoted per project or, more often, not quoted at all. In a delivered building the second number can exceed the first, and it is the one that decides whether the project is profitable.
What commissioning actually involves
Every point needs an identity. A switch is not a switch, it is the second gang in the master bedroom. Every scene needs a definition. Every schedule needs a season. Every room needs a handover sheet the occupant can follow.
Then it needs to be tested as a system rather than as devices: does the corridor scene still work when the gateway on floor three is offline, does the guest room fall back to wall control, does the alarm path reach the operator.
That work is skilled, it is on site, and it is measured in hours per point. A hundred-point apartment building is not a hundred devices, it is several hundred points once scenes and schedules are counted.
Why it is invisible in the quotation
Commissioning sits between two parties who each assume the other has it. The factory quotes hardware FOB. The integrator quotes installation labour. Neither quotes programming and acceptance, so it is absorbed, usually by the integrator, usually at a loss, and usually by cutting the acceptance testing that would have caught the problems.
The consequence appears months later as a support burden: repeated site visits to fix scenes that were never properly defined.
Price it per point, not per square metre
Area-based pricing is intuitive and wrong. Two apartments of the same size can differ threefold in point count depending on how many circuits, how many scenes and how much automation the owner specified.
Per-point pricing is defensible, comparable and easy to audit. It also forces the design to be counted before the project starts, which is where most of the savings actually come from.
A useful structure is three lines: points, scenes, and handover. Points scale with the building. Scenes scale with ambition. Handover is fixed per project.
Design decisions that cut commissioning time
Predefined room templates cut it substantially. A standard guest room or a standard two-bedroom apartment configured once and cloned with a per-room naming pass is far faster than designing each room from scratch, and it produces a system the operator can actually understand.
Naming conventions cut it further. If every room follows the same pattern, a maintenance technician can find a device without a drawing.
Fewer gateways per zone with clear zone names cut it again, because troubleshooting starts with knowing which zone a device belongs to.
None of these are hardware features. All of them are deliverables a factory can prepare once and reuse across projects.
The handover document is part of the product
An operator who receives a system without a device schedule, a scene list and a fallback procedure will call the integrator for every change. That call volume is a cost that was never quoted.
A one-page-per-room sheet with device names, scene names and what to do when the network is down removes most of the first-year support load.
Questions to ask before signing
Who commissions, and is that in the price. How many points are counted, and how is a point defined. What is the acceptance test, and who signs it. What documentation is handed over. What happens when a device is replaced, does the configuration survive.
The last question matters more than it appears. If a replacement device needs full re-pairing and re-scening, every failure costs an hour. If the configuration is stored and restorable, it costs ten minutes.
Hardware choices that reduce site time
Devices that pair without a tool, configurations that can be cloned between rooms, and a gateway that exposes a backup and restore path all shift hours out of the building and into the factory.
That shift is where a supplier earns a premium that survives a price comparison. The cheapest hardware with the most site work is the most expensive project.
The room controller and gateway range we build, and the commissioning documentation we provide with project orders, are described on the home automation system manufacturing page. Read it while the point count is still being argued, because that is the moment the commissioning cost can still be designed out. Point counts and room types can be sent through the contact page for a commissioning estimate before the tender is fixed.
