- Light scenarios and an air-conditioner schedule
- Motion sensors in passage areas
- Switches work without the hub

Smart Home
A Smart Home that does not break when the internet goes down
light, climate, curtains, access — local, not cloud-dependent
We start from the wiring and the choice of an ecosystem after an audit, not from buying sensors. Scenarios for light, climate, curtains and access run on a local hub, while ordinary switches and air-conditioner remotes keep working.
Status: the solution is assembled for a site; the ecosystem is chosen after checking the wiring and the network. The contract must list the «smart» functions as a separate line.
01 · Who it is for
Smart Home: who it is for
- Owners of new villas and flats who want «night», «away» and «guests» scenarios without depending on the cloud.
- Those who already have some devices and need to bring them into one system.
- Managers and landlords: climate and access control.
02 · What the system consists of
Hub
A local scenario controller in the house; a settings backup
Panels and app
Wall panels for an 86 box, phone, voice
Light
Relays and dimmers, link with KAR Light
Climate
Air-conditioner control, temperature and humidity sensors
Curtains and blinds
Motor drives; dry contacts and relays
Access
Locks, intercom, gate; an opening log
Network and PoE
PoE budget, switches, UPS
03 · How it works
How it works
- 01Wiring comes first
Where sensors, panels, curtains and relays are needed, we lay cables and deep boxes. Panels powered at 24 V DC suit places where two cores are laid.
- 02A local hub
Scenario logic runs on a device in the house. The cloud is for remote access, not for making a switch work.
- 03Scenarios
Light by presence and time of day, climate by schedule and sensors, curtains by sun, access by code and card.
- 04Compatibility
We rely on open protocols (for example Zigbee, Matter, KNX, Modbus/RS485, Ethernet/PoE) so you are not tied to one manufacturer.
04 · Three levels
Basic / Mid / Premium
- Everything in Basic
- Curtains, opening sensors, climate per room
- Wall panels
- One control panel with KAR Light and sound
- Everything in Mid
- Access: locks, gate, an intercom with a log
- Energy metering and a link with a solar plant
- «Away», «guests», «vacation» scenarios, a spare hub
The content of each level is confirmed after a site visit; the price is in the estimate, not on the site.
05 · What the work includes
- Wiring and network audit
- Ecosystem choice and a device list
- Connection schemes, sensor and panel positions
- Scenario setup and training
- As-built scheme, access details and a backup
What is not included
- Cloud-service subscriptions
- Rewiring the whole house (if needed — separately by project)
- Security services
06 · Stages of work
Stages of work
01
Request and description
What you want to automate, what is already there.
02
Audit
Wiring, network, panel and sensor positions.
03
Ecosystem and scheme
Hub, protocols, list.
04
Options and sourcing
Three composition levels.
05
Installation and setup
Cables, devices, scenarios.
06
Testing and handover
A check without internet, training, documents.
07 · Timing
- What affects timingScope and number of zones, the finishing stage on site, supplier availability and how fast decisions are made.
- When we name the timingAfter a site visit and calculation: it is fixed in the estimate and work plan, stage by stage. We do not promise fixed timing in advance.
- What must be done on timeCables and boxes go in before walls and ceilings are closed. Equipment can be chosen and installed later.
08 · What we need from you
- Floor plans or photos of the rooms; the electrical and finishing design if available
- Access to the site for a visit and measurements
- A decision on the level (basic, mid, premium) after the calculation
- One contact person who approves decisions and changes
- The finishing schedule, so cables go in before walls are closed

10 · FAQ
FAQ
A description of the solution, not an offer.
Why audit the wiring?
A sensor does not help if there is no cable to the spot. The audit shows what is possible and what needs opening up.
If the internet goes down?
Scenarios and switches work locally. Remote access and streaming do not.
Can I keep ordinary switches?
Yes. They stay working; the «smart» part is an add-on.
Does data leave the house?
Not by default: scenarios run locally. Any cloud function is enabled separately, with your consent.
