Most people use “smart electrical” and “smart home” to mean the same thing, but from an engineering point of view they are two different layers. Understanding the difference is what decides whether the system works as one whole or stays a collection of gadgets.
In short: Smart electrical is the infrastructure: circuits that can be controlled, controllers in the panel, and the ability to operate any point remotely. A smart home is what is built on top of that infrastructure: the integration between the systems and the scenes that connect them.
You can have smart electrical without a smart home: infrastructure that is installed but not used. You cannot have a smart home without smart electrical.
What smart electrical at home includes
The infrastructure has three layers that need to be designed together. When one is designed on its own, the gap shows up during the build:
The electrical panel
The controllers sit in the panel, so it is larger and more complex than a conventional one. It is an item people tend to forget in the design, and it comes to light when there is no room left.
Circuits and control points
Every circuit you want to control has to reach the panel separately. The number of points is what determines the scope of the system and its price, more than any other factor.
Communication infrastructure
How the controllers talk to each other: a dedicated control cable in a wired system, or a planned wireless network in a wireless one.
What can be controlled
- Lighting. On and off, dimming, lighting scenes by time of day or activity. This is the largest item in most projects.
- Shutters and curtains. Motorised opening and closing, scheduled by time of day and by the weather.
- Air conditioning and heating. Room-by-room climate control, automatic shut-off when a window opens, adjustment to your habits.
- Water heater. One of the items with the fastest payback: controlling the water heater alone offsets part of the cost.
- Security and cameras. The alarm system and cameras brought into the same control environment.
- Irrigation and outdoor lighting. Garden scheduling, yard lighting and automatic gates.
Wired or wireless: how to choose
This is the most important infrastructure decision, and it follows from the condition of the property more than from any technology preference:
| Aspect | Wired smart electrical | Wireless smart electrical |
|---|---|---|
| Suitable stage | New build or major renovation | Existing home, no building work |
| Infrastructure requirements | Dedicated conduits and a control cable | The existing electrical wiring |
| Initial cost | Higher: infrastructure and hardware | Relatively low |
| Reliability | Very high, independent of the network | Good, depends on the network design |
| Future expansion | Planned into the infrastructure in advance | Modular, added step by step |
In practice, a large share of the projects we carry out are hybrid: wired KNX infrastructure for the core (lighting, shutters and air conditioning), and wireless components where no conduit reaches.
What determines the cost
The gap between quotes almost always comes from a different scope, not a different equipment price. Four items explain most of the difference:
- The number of control points. A home with 40 lighting points is fundamentally different from one with 15.
- The type of control. On/off is much cheaper than dimming, and standard dimming is cheaper than dimming with advanced technologies.
- The electrician’s work. An addition that can reach tens of percent compared with a conventional project.
- The choice of switches and fittings. A single premium switch can cost thousands of shekels, multiplied by dozens of points.

How to design smart electrical properly
1. Start before the concrete is poured
Point locations, conduit diameter and panel size are decided on paper at almost no cost. The same change after the pour costs tens of thousands. Consulting and early design is the investment with the highest return in the project.
2. Keep design and execution separate
Whoever designs the system should not be whoever sells the equipment. Independent design ensures that the technology recommendation comes from the home’s needs, not from the brand the installer represents.
3. Supervise the work at the critical stages
Before the pour, when the conduits are finished and before plastering, and when the panel is closed. A defect caught after plastering costs several times more to fix. Supervision at these stages is insurance, not an extra expense.
4. Insist on documentation at the end
A panel drawing, a controller map and a list of scenes. Without that documentation, any future technician has to map the system again, and that is the most expensive stage of any restoration of an existing system.
Smart electrical: questions, answered
What is the difference between smart electrical and a smart home?
Smart electrical is the infrastructure: controlled circuits, controllers in the panel and remote operation. A smart home is the integration layer that runs on top of it: the scenes that bring lighting, air conditioning, shutters and security together into one system. Smart electrical infrastructure without scene design remains a collection of remote switches.
Can smart electrical be installed in an existing home?
Yes. A wireless system is installed on the existing electrical wiring: the components go inside the wall boxes and the electrical panel, without chasing or breaking walls. In a standard apartment, installation takes one to three days and can be done while you live there.
How much does smart electrical for a home cost?
A basic wireless system for lighting and air conditioning starts at around ₪15,000. A comprehensive system for a private house usually costs between ₪80,000 and ₪150,000. The biggest factor is the number of control points and the type of control at each one, not the price of the equipment itself.
Can an ordinary electrician install smart electrical?
An electrician builds the infrastructure and the panel, but designing the system logic, programming the controllers and integrating the systems take separate knowledge. In most of the faults we are called to fix, the electrical work was sound; what was missing was the design and programming layer.
Does the system keep working without the internet?
Yes. Switches, lighting scenes and climate control run locally without an internet connection. The only thing that stops is remote control through the app, and it comes back as soon as the connection does. In a wired system the local independence is even more complete.
How much electricity does a smart electrical system save?
The savings come mainly from three items: running the water heater by actual use, switching lights off automatically in empty rooms, and controlling air conditioning by occupancy. In the homes we have guided, the biggest item is almost always the water heater. The payback depends on how you use the home, not only on the equipment.
Where to next
Planning smart electrical?
A short scoping call is enough to understand the scope of the project and get a realistic price range, before the electrical work begins.
