1. Senses
The device measures
Noise, headcount, door openings, temperature, water leaks – no cameras or audio recording, over an encrypted connection.
GDPR-compliant • no audio recording • no camera
Continuous monitoring: without cameras, without disturbing the guests.
Real-time monitoring, radar occupancy counting, and heating and cooling control for short-term rental. It protects the peace of the building, the furnishings and the energy bill while guests' privacy stays intact.

How does it work?
Not standalone devices, but parts of one system
The devices connect to the hostAID system over an encrypted connection. That is why they don't work on their own, and why the system can act by itself.
2. Compares
The system decides
It compares the measured data with the booking: how many guests are inside, when they arrive, what the house rules allow.
3. Acts
Acts at once
Signals the guest, controls the heating, shuts off the water and notifies our customer service.
Devices
Three jobs it solves
Choose what matters to you. You'll find the prices at the bottom of the page.
Peace in the building
So the neighbours aren't talking about your guests.
Access without a key handover
The guest gets in on their own, and you see who opened and when.
Utilities and damage prevention
Less wasted energy, and no flooded neighbours.
01 / Peace in the buildingGDPR-compliant
Noise detector
It doesn't record audio or listen in: it only measures the sound pressure level (dB). That prevents neighbour complaints, police call-outs and local authority proceedings.
Legal certainty in the condominiumUnder Regulation (EU) 2016/679 (GDPR) the measurement does not count as an image or audio recording. The measurement log can also be shown to the building manager.
Four-step noise management
- 1Signal in the apartmentIf after 10 in the evening the noise stays above the 65 dB limit, the device in the apartment signals the guests to keep quiet.It doesn't sound the alarm on every door slam
- 2Audible warning in EnglishThe device warns guests out loud, in English, to keep it down.Most cases are resolved here
- 3Phone callIf the noise continues, our customer service calls the guest.0–24-hour customer service
- 4Patrol on siteIf the guest still doesn't stop, a Red Raven patrol goes out to the site.No complaints at the residents' meeting
02 / Peace in the building60 GHz radar
Camera-free occupancy sensor
Millimetre-wave radar and low-resolution thermal sensing. It cannot capture an image or a face, yet it determines accurately how many people are in the apartment.
- Unauthorised partyIf 8 people arrive on a booking for 2 guests, the system alerts the manager within 8 minutes.
- PrivacySince it is not a camera, it can be used in the bedroom and bathroom too. The guest can rest undisturbed.
60 GHz radarBooking: 2 guests • present: 7
Group 1 (3 guests)
Group 2 (4 guests)
Status: there are more guests inside than on the booking. The manager has been notified.
03 / AccessAES-256 encryption
Smart lock without a code, with our own gateway
Fully automatic access, with no key copying and no lost keys. The guest opens the door and the gate with a link or an app, only from arrival to departure.
- No keypad and no code: nothing tells a burglar there is a rental behind the door.
- The digital key expires automatically at check-out time (e.g. 10:00).
- Cleaners get separate permissions, and we log their entry and exit times.
- The guest gets in when the property is ready. If it's ready early, they can get in early.
- If a staff member is working in the apartment, a guest who hasn't arrived yet waits until they are done.
- We log every opening, including failed attempts.
- PoE power or a lithium battery that lasts approx. 14 months, with a low-battery warning.
In-house smart lock
A motorised unit that fits Euro-profile multipoint locks. No door replacement needed, and it is quick to fit. The guest opens it with a link or an app.
Still opens with a key
In-house gateway
It manages several lock platforms in one system: currently our own locks, plus TTLock and Nuki locks. The number of supported platforms keeps growing.
An existing Nuki or TTLock lock can be connected too
04 / Utilities27–38% savings
Heating and cooling control
The biggest hidden utility cost in short-term letting: air conditioning set to 18 degrees with the window open, or an empty apartment heated to 25 degrees in winter. Our system prevents this, and also flags immediately if the heating or cooling fails.
Open-window detection
If the guest leaves the window open for more than 3 minutes, heating or cooling in that room switches off.
Economy mode in an empty apartment
After check-out the temperature is set to 19 °C (winter) or 27 °C (summer), and an hour before the guest arrives the system heats or cools the apartment based on the calendar.
Night programme
At night the system lowers heating or cooling by itself, and by morning it returns to the daytime temperature.
Monitors the outdoor temperature
The control adapts to the weather: it heats less in mild weather and starts cooling in good time in a heatwave.
Instant fault alerts
If the boiler stops, the water pressure drops or the apartment cannot reach the set temperature, we get an alert immediately and take action. It also warns of frost and mould risk.
Works even without a connection
If the internet connection drops, the local controller keeps the set temperature on its own until the connection is restored.
What else we make smart
- Not just air conditioning: we make any radiator and boiler remotely controllable
- Several rental units in one building: separate heating and cooling for each unit
- Jacuzzi controlled remotely or automatically, in line with bookings – see below
- Guests can set the temperature on the guest portal, within the limits you define
Heating and cooling in a month (kWh)Protected by automation
Without automation620 kWh
Controlled by hostAID420 kWh (−32%)
Estimated savings: in season, approx. HUF 12,000–16,000 per apartment per month
05 / Utilities and guest experienceWith a Balboa controller
Jacuzzi controlled remotely, in line with bookings
There's no point keeping a jacuzzi hot on empty days, but guests expect warm water when they arrive. We connect it to our system: it rests when there are no guests, heats up in time, and if it reports a fault, we know right away.
Not every jacuzzi can be connectedAt the moment we can make jacuzzis with a Balboa controller smart. If you don't know which controller yours has, send us a photo of the control panel or the controller box and we'll check. The control panel works just the same after we connect it.
In line with bookings
On empty days it sits in rest mode, then heats up on its own in time for the guest's arrival. We don't heat the water needlessly.
Temperature, remotely
You see the water temperature and can remotely set the target temperature and the low or high temperature range.
Filter cycles
Filtering start time and duration can be set remotely. The system keeps the jacuzzi's clock accurate, so filtering starts exactly when set.
Instant fault alerts
If the jacuzzi reports a fault or the connection drops, we know right away, before the guest has to tell us.
Also controllable remotely
- Switching the massage jets and air blower on and off
- Switching the lights on and off
- Live status of heating and circulation
- Jacuzzi reminders (such as filter cleaning) in the system, acknowledged remotely

06 / Damage preventionImmediate protection
Burst-pipe and water-leak sensors
A flexible hose that cracks overnight or a blocked shower tray can cause millions of forints' worth of damage in the apartment and to the neighbour below. The sensors don't just notify, they act on their own.
- Motorised shut-off valveWhen it detects moisture, it shuts off the apartment's main stopcock within seconds.
- 0–24-hour fault responseImmediate notification to the dispatch service and the maintenance team.

Fees
As a service, at an introductory price
Our devices only work with our own system, so we don't sell them as separate products: you get them as a service, for a low monthly fee and a one-off device fee.
If we manage your property, there is no monthly fee. You only pay for the device and the installation, once.If you manage your property yourself, for the monthly fee you use the narrower, device-management version of our system; the full PMS is for our management clients.
