Smart Home Installation: What to Plan Before First Fix
A smart home installation is easiest to get right before the electrician starts first fix. At that stage, the decisions are not about choosing every screen, speaker or keypad. They are about putting the right cables, routes, power and equipment space in the right places while the structure is still open.
For an Irish new build or major renovation, a coordinated plan at this point can prevent visible retrofit work, compromised equipment locations and late changes on site. This guide covers the decisions Formwave normally resolves before first fix.
What first fix means for a smart home
First fix is the stage when electrical and data cabling, back boxes and containment are installed before walls and ceilings are closed. It is the best point to coordinate the infrastructure for the network, televisions, audio, lighting control and future systems.
You do not need to select every finished device at this stage. You do need a clear plan showing where services begin, where they finish and how they connect.
1. Choose the central equipment location
Start by deciding where the network and control equipment will live. This may be a dedicated comms cupboard, utility space or plant-adjacent area, but it needs enough room, power, ventilation and access for installation and servicing.
Avoid treating the equipment location as whatever space is left at the end. A hot, cramped cupboard beside a boiler or cylinder can create unnecessary constraints. The location should be agreed early and shown clearly on the electrical drawings.
2. Plan the wired network before Wi-Fi
Good Wi-Fi starts with a wired network. Formwave’s normal design approach is to position a wired access point in each main living space, with each cable run returning to the central comms point. The exact number and position depend on the floor plan, construction and coverage required.
We normally specify solid-copper Cat6A cable for new project infrastructure. Cable routes, access-point positions and the comms location should be coordinated together, not decided separately.

3. Mark every TV and media position
Each main TV position needs more than a nearby socket. For a typical Formwave layout, we normally allow two or three data cables at each principal TV point, with the final cable bundle adjusted to the sources, control method and room design.
Also decide whether equipment will sit locally or in the central rack. If a television, projector or media space may change later, a suitable conduit can preserve options that would otherwise require opening finished walls.
4. Define audio zones room by room
Decide which rooms need audio and how each space should behave. Two adjoining rooms can be one audio zone if they will always play the same source at the same volume. If they need independent control, they should be planned separately.
Speaker positions should be coordinated with lighting, joinery, ceiling features and furniture. This avoids clashes and gives the electrician or specialist installer a clear route for each speaker cable.
5. Set the lighting-control strategy
Lighting control affects circuit grouping, dimming, switch wiring and keypad positions. Those decisions belong on the first-fix plan. Waiting until the switches are being fitted can limit the control options or require changes to completed electrical work.
At this stage, agree which loads need control, where wall controls will sit and which everyday scenes matter. The exact keypad finish can be selected later if the underlying design is already correct.
See Formwave’s home lighting control design service for the planning process.
6. Allow routes for future systems
Not every future requirement needs cable on day one, but difficult routes should be considered while the building is open. Project-specific conduit may be useful between the equipment location and principal TV positions, a projector location, the roof space, garden or an outbuilding.
The useful question is not simply, “Can we add it later?” It is, “Will the route, power, cable and equipment space still be available later?”
What the electrician should receive
A smart-home first-fix pack should give the electrical contractor one coordinated reference rather than a trail of separate messages. It will normally include:
- Marked plans for network, TV, audio, lighting-control and equipment points
- A cable schedule and labelling convention
- The destination for every home-run cable
- Equipment-space power, ventilation and access requirements
- Speaker, access-point, TV and control positions
- Required conduit routes
- A clear division of responsibility between the electrician and specialist installer
The final specification should be tailored to the property. A standard checklist cannot account for every floor plan, construction type or system choice.
When to involve a smart-home integrator
The most useful time is before the first-fix drawings are issued and before the electrician has committed to the cable layout. Formwave can review the architectural and electrical plans, identify the decisions that affect infrastructure and produce a coordinated design for the project team.
