The Ubiquiti USL-Entry SuperLink smart sensor is a wireless sensor for detecting the opening or closing of doors and windows in smart homes or business premises. It is intended for users who want to easily monitor access to their premises and receive notifications when there is a change in status. Using the sensor provides immediate information about what is happening at the door or window, regardless of where you are, as it works remotely via a radio connection.

The device works without the need for a classic control panel, which means there are no complex connections or additional cabling. This makes it easier to install in various rooms where a traditional wired solution would be less practical. Powering with the included batteries allows for long-term operation without a permanent power source, so the sensor is also suitable for rooms where there is no access to sockets.

Using a radio connection, the sensor reaches a distance of up to 2000 meters in open space, which in practice means that you can wirelessly connect the sensor to more distant doors or windows in larger apartments, houses or commercial buildings. Since it does not use standard WiFi or ZigBee connections and can be connected to alternative systems, it remains easy to use and adaptable to your existing smart system.

The modern and discreet design in white allows the sensor to visually blend in with most interior or exterior door and window frames. Due to its easy installation and wireless operation, it is suitable for anyone looking for a practical solution for greater transparency over what is happening in the room - at home or on the weekend.

It is important to know

When choosing a smart door and window sensor like the Ubiquiti USL-Entry SuperLink, it's crucial to consider the environment you'll be using it in and how it will connect to your system. While the wireless connection is impressive, the main question you should ask yourself before making a decision is how the sensor will work with your existing smart home and what functionality you really need.

• Connectivity: Before purchasing, check whether the radio connection method is compatible with your central system or any central unit if you already have one.
• Battery power means fewer cables and easier installation, but it does mean the occasional need to change batteries – plan for this when installing in hard-to-reach places.
• The radio range of up to 2000 m is theoretically high, but real-world performance can be affected by thick walls, metal surfaces, or larger buildings.
• The sensor is specialized for doors and windows; to protect against other types of hazards (e.g. smoke, gas or water), you will need to consider other types of sensors.
• Integration: For more advanced automation and greater scalability, check out the options for integrating the sensor into a broader smart home system.

In practice

🟢 Door and window monitoring

Perfectly suitable - the sensor is designed for this purpose, provides notification when opened and is suitable for basic home or office protection.

🟡 Integration into an existing smart home

Suitable with restrictions – operation in a larger system is possible if compatibility with the control panel is ensured; check beforehand whether your system supports this type of radio connection.

🟢 Use in facilities with a longer range

Very suitable - the declared range allows installation even in larger houses or remote facilities, but obstacles in the room may reduce the range.

🟡 Use without a power cable (battery powered)

Suitable with limitations – the installation is flexible, but be prepared to change batteries occasionally, especially with frequent use or demanding conditions.

🔴 Motion or smoke detection

Less suitable – this sensor is not designed to detect motion or smoke; you need a dedicated detector for that if these scenarios are important to you.

Answers to frequently asked questions

Does the sensor work even if the room is remote and has solid walls?

The sensor has a high declared radio connection range, but massive walls or metal obstacles can reduce the range.

Can the sensor be easily moved to another window or door?

Thanks to its battery power and wireless connection, you can move the sensor whenever you want – just make sure you have a brand new mount.

How often should the battery be changed?

The frequency of replacement depends on use and location, but regular checks of battery performance and condition are usually sufficient.

Do I need a control panel to use this sensor?

We recommend that you check before purchasing whether your system supports this type of radio communication and whether an additional control panel is required.

What is needed for smart home integration?

For more advanced automation, you must ensure the sensor is compatible with the selected smart system or control panel.
