Smart home
A smart home that does not break when the internet goes down
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.
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.
01
How it works
- Wiring comes firstWhere 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.
- A local hubScenario logic runs on a device in the house. The cloud is for remote access, not for making a switch work.
- ScenariosLight by presence and time of day, climate by schedule and sensors, curtains by sun, access by code and card.
- CompatibilityWe rely on open protocols (for example Zigbee, Matter, KNX, Modbus/RS485, Ethernet/PoE) so you are not tied to one manufacturer.
02
Components and scheme
| 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 |

Mid
- Everything in Basic
- Curtains, opening sensors, climate per room
- Wall panels
- One control panel with KAR Light and sound
Premium
- 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

FAQ
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.
