Frequent questions

What is the Connection Unit?

The Connection Unit is the system controller, which allows every IRSAP NOW device to communicate with the others and provides the necessary information to each component of the system so that it works at its best to achieve the desired comfort. Every setting in the app can only be communicated to the devices through the Connection Unit, thus making it the essential device for the operation of the IRSAP NOW System. The Connection Unit is also a backup for the "house" settings (amount of items connected, time slots, geofencing, etc), so the system will run even in the event of an Internet connection loss.


The Connection Unit is a compact device (104 x 48 x 28 mm), and it is shipped with the following accessories: 1 Ethernet cable, 1 USB/ micro USB cable, 1 power supply, 1 EU plug adapter, 1 UK plug adapter, QR code for instructions.

What do I need for the Connection Unit to work?

The Connection Unit works by connecting to an electrical outlet and an Ethernet cable to be connected to the router.

Alternatively, if your router is set up, you can power the Connection Unit by connecting the USB cable directly to the router.

The Connection Unit is shipped with the following accessories: 1 Ethernet cable, 1 USB/ micro USB cable, 1 power supply, 1 EU plug adapter, 1 UK plug adapter, QR code for instructions.

I need to replace the router, should I replace the Connection Unit also?

If you decide to replace the router, you can simply connect the Connection Unit Ethernet cable to the new router.

The associated devices and the saved settings will not be cancelled from the app.

You can check the correct connection of the devices through the operating LED (find more information about the LED in the questions in this section);
In case an error is detected, you will also receive the relevant notification through the IRSAP NOW App.

How does communication between devices in the NOW System take place?

The Connection Unit communicates with IRSAP NOW devices via RF (radio frequency, 868Mhz).

Connection Unit Setup and Configuration Wizard

Connect the Connection Unit to the router and power supply;

Power with connection to the router:


Power supply with power grid connection (EU adapter, top right UK adapter):


Check the connection: the LED signal will be flashing red;

Download the IRSAP NOW app, set up your home and add the Connection Unit: follow the video wizard and frame the QR code you find in the package, this will record and associate the Connection Unit with your home system.

The LED light will be green.

Where should the Connection Unit be installed?

For the optimal operation of communication between NOW devices, we recommend you to place the Connection Unit in the center of the System, so that the communication (radio frequency transmission) is uniform between all the installed devices.

In general, the range of the Connection Unit is about 10 meters, however the width could be reduced due to the structure of the building (e.g. thick or stone walls, presence of metal/shielding panels).

If you need to extend or strengthen the signal, you can add one Connection Unit to your system and activate it in Repeater mode.

I don't have an Ethernet cable, can I connect the Connection Unit to WiFi?

Unfortunately, the Connection Unit cannot be connected to a WiFi network, but only to a router;

However, among the connection unit accessories supplied you will also find an Ethernet cable.
