Make every guest room behave the same way: power that follows the keycard, aircon that is off when the room is empty, and simple scenes guests understand.
📍 We serve KL, Selangor & Putrajaya.

Hotel room automation for a boutique hotel ties the keycard power holder, the aircon, the lights and the curtains of each room to a few simple scenes, so rooms are comfortable when guests arrive and nothing runs once they leave. Keep the guest controls simple, keep cameras and listening devices out of rooms, and retrofit one floor at a time. The keycard holder and lighting are electrical work. For homes, see smart home installation.
Large hotels run a building management system tied to the front desk software. A boutique hotel or guesthouse with a handful of floors rarely needs that. What it needs is every room behaving the same way: power and lights that follow the guest, aircon that is not left running for an empty room, and a housekeeping team that can see which rooms are ready.
That can be built from the same devices used in homes, provided they are chosen for many identical rooms rather than one family. The rest of this guide goes through the room one layer at a time: the keycard holder, scenes, aircon, lights and curtains, privacy, resets between guests, locks, the retrofit itself and the electrical side.
Most hotel guests know the slot by the door: put the card in and the room comes alive, take it out and the room powers down. Wikipedia's keycard lock entry notes that keycards are widely used in hotels and shows a hotel entry card used to enable a light switch. Its occupancy sensor entry counts hotel room keycard locks among occupancy sensors, devices typically used to save energy.
The weakness is well known: a guest leaves any card in the slot and the aircon runs all day. A presence or motion sensor in the room, combined with a door contact, gives the system a second opinion. If the door opened and closed and nobody has moved inside for a while, a smart setup can switch the aircon to an economy setting and turn off the lights, while the sockets for phone chargers stay on.
A scene is a saved set of states for several devices at once. Home Assistant's documentation describes a scene as storing the states you want for a group of entities, such as one light on and another set to a colour. Hotels need only a few, and every room should use the same names so housekeeping and guests learn them once.
| Scene | Lights | Aircon | Curtains |
|---|---|---|---|
| Arrival | Entry and bedside lights on, warm tone | Running at a comfortable setting | Open by day, closed at night |
| Sleep | All off except a low night path to the bathroom | Quiet mode | Closed |
| Away (card out) | All off | Off or economy | Left as the guest set them |
| Housekeeping | All on, bright | Off | Open for daylight and air |
| Vacant and ready | Off | Off until the next check-in | Closed |
Put the scenes on a simple wall panel or bedside button. Guests will not download an app for one night, and they should never be asked to.
Aircon is usually the largest running cost in a small hotel and the easiest to waste. Two habits make the difference: rooms that are empty stay off, and a room is cooled shortly before the guest arrives rather than all afternoon. With wall-mounted split units, an IR controller in each room lets one app switch them by schedule, by check-in status or by the keycard state. The smart aircon control guide covers how IR control works with the units hotels already have.
Ducted or central systems are a different case: their own controllers and the aircon supplier decide what can be linked. Ask before buying anything, and keep the guest's own remote working in every room.
Hotel rooms suffer from the hunt for the right switch at midnight. A master off at the bedside, a dim path light to the bathroom and a clear entry switch solve most of it. Smart switches and dimmers on the room's lighting let those be programmed per room rather than rewired, but changing switches is electrical work, covered further down.
Motorised curtains help where windows are large or hard to reach, and they let the vacant scene close every room against the afternoon sun. The curtain motorisation guide explains battery and wired motors and which tracks they suit; in a hotel, quiet operation and a manual pull for guests matter more than speed.
A room is the guest's private space, so leave out anything that watches or listens. No cameras inside rooms, and think hard before adding voice assistants with microphones; if you do, show guests how to mute them and clear their history between stays. Motion and presence sensors that only report occupied or empty are a different matter, but tell guests what is in the room.
Logs are personal data too. Wikipedia notes that key card systems raise privacy concerns because they allow each entry to be recorded. Limit who can see door and occupancy history, keep it only as long as you need it, and check your obligations under the PDPA with your adviser.
Guests should never sign in to the hotel's smart account, and no room device should depend on a guest's phone. Room controls live on the wall panel or remote; the owner's account and a separate housekeeping access run everything else. If anything personal can be stored, such as a casting session or a voice history, add it to the checkout list.
Keep room devices off the guest WiFi. A separate network for the hotel's devices stops a guest from seeing or controlling another room. The smart device network security guide explains how to split the networks on a typical router.
Hotel keycard locks are normally a system of their own, programmed at the front desk. Room automation can read the keycard holder and a door contact without touching that lock system. A small guesthouse without a front desk may prefer code locks that change per booking, which the smart lock guide for short-stay rentals covers.
Guest room doors and corridor doors in sleeping accommodation may be part of the building's fire design. Before changing any door, lock or closer, check with your fire consultant or Bomba; the guide to smart locks on fire-rated doors explains why the hardware matters.
Start with one mock-up room. Fit it, live with it for a few stays, and adjust the scenes, the keycard rules and the panel labels before copying it. Then work floor by floor so only a few rooms are out at once. Building works such as bathrooms, partitions and corridors follow their own plan, which the boutique hotel renovation guide sets out.
Choose a platform that keeps working without the internet, because a dropped line should not leave a full house unable to switch on the lights. The local control guide explains which hubs run scenes locally. For a homestay rather than a hotel, the homestay smart setup guide is the closer fit.
A keycard power holder switches the room's supply, so fitting or replacing one is electrical work. So are smart switches and dimmers on room lighting, wired curtain motors and any new power point for a hub or panel.
For smart switches and anything wired into the mains, we supply the devices and set up the app, and the switch or wiring work is done by an electrical contractor registered with Suruhanjaya Tenaga that we coordinate.
Any mains electrical work, such as a new power point, a change at the distribution board or a hardwired switch that needs new wiring, must be done by an electrical contractor registered with Suruhanjaya Tenaga.
Smoke detectors, fire alarms, emergency lighting and exit signs belong to the building's fire design and should stay separate from room automation. Ask your consultant or Bomba what applies to your premises.
| Decide first | Why it matters |
|---|---|
| Which sockets stay live with the card out | Chargers and the minibar should not die mid-stay |
| The same scene names in every room | Staff and guests learn them once |
| How the aircon is controlled today | Split units suit IR control; central systems need the supplier |
| Where the controls sit for guests | A wall panel or remote, never an app |
| What records are kept and who sees them | Door and occupancy logs are personal data |
| A separate network for room devices | Keeps guests away from each other's rooms |
| One mock-up room before the rest | Problems are cheap to fix in one room |
We start with a mock-up room: we install the IR controllers, presence and door sensors and the hub, supply the keycard holders, smart switches and curtain motors that suit your rooms, and set up the scenes, schedules and housekeeping access with your team. We do the smart device, app and low-voltage side of the job. Tell us the number of rooms and floors, the aircon type and whether the hotel already has a keycard system.
