In every room a radar presence sensor, a contact on the window and a call button. Reception, housekeeping and maintenance see which rooms are occupied, where a window is open and who has asked for service. All battery powered, installation without building work, LoRaWAN radio transmission.
What it does
- The presence sensor combines a millimetre-wave radar and a passive infrared: it recognises a moving person up to 7.5 m away and the small movements of someone still or seated up to 4.8 m. The occupied or free status of each room reaches the platform as soon as the status changes.
- Housekeeping sees in real time which rooms are empty and organises the round of the floors without knocking. Maintenance goes in while the guest is out.
- The contact on the window reports opening and closing. With the rule «window open for more than 3 minutes» a notification is sent, or the data is passed to the system that controls the fan coils so that air conditioning in that room is suspended.
- The presence status serves the same purpose: room empty, setback temperature. The kit supplies the data; control of the air conditioning remains with your own regulation system, if it is set up to receive it.
- The button distinguishes a short, a double and a long press: a request is associated with each one, and it arrives as a notification at reception or housekeeping with the room number.
- No device captures images or records audio.
- The history and the status of all the rooms can be consulted from a smartphone and from a PC.

Milesight devices of the highest quality with the manufacturer's warranty. Batteries included in all the sensors; only the gateways are mains powered via USB-C 5 V.
Available sizes
The size is chosen at the top, together with the version and the connectivity. The diagram, the photo and the table above show the «30 rooms» size; with the other sizes only the quantities of the devices listed below change, the rest of the kit is identical.
- 10 rooms: 10 radar presence sensors, 10 magnetic contacts, 10 call buttons
- 20 rooms: 20 radar presence sensors, 20 magnetic contacts, 20 call buttons

Before you order
Is Wi-Fi needed in the rooms?
No. The sensors do not use Wi-Fi: they talk by radio with the gateways, on a different frequency, and they put no load on the guest network. Only the two gateways connect to the hotel network, by cable or Wi-Fi, in a corridor or in a technical room. For properties where the hotel network cannot be used there is the gateway with a 4G modem, which requires a data SIM (not included): ask for it from the contacts section.
Are two gateways enough for all the floors?
For a property of 30 rooms on three or four floors, as a rule yes: LoRaWAN radio passes through walls and floor slabs far better than Wi-Fi, and two gateways in different positions cover each other. The range inside a building depends on walls, slabs and metal structures, which is why the gateways go in a central position and high up. For historic buildings with thick walls, separate blocks or many floors, the options include the «large building» version, in which the main gateway is a model with greater range, IP65 and able to be powered over PoE. Each gateway handles hundreds of devices.
Does the system switch off the air conditioning by itself?
The kit detects and reports: room empty, window open. Switching off or setting back the air conditioning is done by the system that already controls the fan coils or the split units, that is the BMS, the room controller or the management software, if it can receive external data: the gateway sends it via MQTT or HTTP. Without a system of this kind the kit works on notifications: reception knows which room to attend to. Tell us from the contacts section what installation you have and we will tell you what is feasible.
Does the presence sensor film the guests?
No. It is a radar paired with a passive infrared: it returns a single piece of data, room occupied or free. It has neither a camera nor a microphone and it produces no images. It also detects someone who is still or seated; the bathroom, with the door closed, stays outside its field, which is why the «room empty» rule has to be set with a delay of a few minutes.
I have a different number of rooms, or rooms with several windows
The kit is configured on the property: each room has a presence sensor, a contact and a button; for every additional window or French door one contact is added. Among the product options you will find the sizes for 10 and for 20 rooms; for larger properties, suites and annexes, write to us from the contacts section stating the number of rooms, floors and windows: we will send you the composition and the quotation for the adapted kit.
How often are the batteries changed?
The manufacturer states about 5 to 7 years for the presence sensors with 50 detections a day, 4 to 7 years for the window contacts with 30 openings a day, 7 to 9 years for the buttons with 10 presses a day, at 25 °C; the life depends on the quality of the signal. The batteries are lithium and replaceable. The charge level of every device is visible in the app, so replacement can be scheduled with routine maintenance.
Where is the data consulted and are there any fees?
On the manufacturer's app and portal, from a smartphone and a PC, with the status of the rooms, the history and notifications; no fee for basic use. Where there is a BMS or hotel management software, the gateway can also send the data to that system (MQTT or HTTP): the configuration is included.
What happens if the internet is down?
The sensors keep working on their batteries. Room status, window notifications and calls from the buttons go through the connection of the gateways: with the line down they are not delivered and they resume when it is restored. The button in the room does not replace the telephone or an emergency call system. In the «large building» version the main gateway can run rules on board even without a connection to the cloud.
Is an electrician needed? Is drilling required?
No. All the room devices are battery powered: the presence sensor and the contact are fixed with adhesive, the button with adhesive or screws. No cables are run and the electrical installation is not touched. The gateways are powered from a socket via USB-C. All the devices are for indoor use, with IP20 or IP30 protection: no bathrooms, terraces or the outer side of windows.
What is not included
- Fan coils, thermostats, BMS and management software: these are your property's own
- Integration with third-party systems beyond sending the data via MQTT or HTTP
- Smartphones or tablets for reception and housekeeping
- In the "devices only" version: network cable, spare batteries, small fixings and labels
