Air Base Extension

The Loxone Air Base Extension is used to extend the Miniserver, and allows the integration of various devices like sensors, actuator or lighting products that are equipped with the Loxone Air wireless technology.

Up to 128 Air devices can be integrated with one Air Base Extension. The 868MHz frequency band is used for communication (US: 902 MHz to 928 MHz). The Miniserver Go features an integrated Air Base Extension.

The Air Base Extension is installed on a DIN rail in a suitable enclosure.

Connect the power supply and Link communication to the Miniserver and install the antenna.

To ensure optimal signal quality, use the optionally available rod antenna. If the enclosure is made of metal, install the antenna outside the enclosure using the SMA extension cable that is supplied with the rod antenna. Alternatively, a flat adhesive SMA antenna is available.

The Extension starts after switching on the power supply, and the status LED will flash orange after a short time when the connection to the Miniserver is established.

Then follow the pairing procedure

Pairing Air Devices

Pairing Mode

All Air devices have to be paired in Loxone Config via the pairing mode. In delivery state, pairing mode will be active after the power supply has been established.

On most Air devices, the status LED will indicate this by flashing red/green/orange. You can find the exact pairing mode signal in the documentation of the respective Air device.

On battery powered Air devices the pairing mode is only active for 5 minutes to conserve energy. Briefly remove the battery and then reinsert it to reactivate pairing mode, if necessary.

If an Air device blinks only orange, then it was previously paired, but can no longer establish a connection. In this case, you have to activate the pairing mode manually. On most devices, this is done by pressing the pairing button or power cycling the device.

Searching and pairing

To search for Air devices, first click on an Air Interface in Loxone Config, and then activate Air Device Search

The window that opens will list all Air devices that are in pairing mode. This can take a few minutes:

If you select a device here, it will identify itself in different ways. Devices with a status LED will flash it, light fixtures pulse a white light, other devices such as the Loxone Touch emit an audible click. This allows you to assign and name the devices correctly.

Select the desired device, assign a name, room and installation location and add it to the programming using the Pair Device or + button.

The right window lists all the devices that are currently part of the program. You can display them by clicking the button Show my Air devices. You can also replace an existing device with a new device of the same type that was found in the search. This is useful when a device needs to be replaced or devices are added to a pre-configured program. Select the device to be added and the device to be replaced. By clicking on the button with the arrow pointing right, the old device is replaced with the new one in the program.

To apply the changes, save the program in the Miniserver.

Now the added devices are ready for use and the functions are available in the Periphery Tree in Loxone Config.

The Loxone App, under Settings, also supports searching for and pairing Air devices.

Pairing Air Devices automatically

The automatic pairing of Air devices can be activated in the properties of the Air interface for a certain duration:

To pair Air devices automatically via the Air, the Air device must be added in the Config. Therefore click on the Air interface and select the desired device via "Add Air Device".
In the properties window of the respective Air device, the serial number must now be entered:

Then save the program to the Miniserver.

Approximately 3 minutes after saving to the Miniserver or restarting the Miniserver, it searches for new Air devices for 4 minutes. Air devices must be in pairing mode in order to be learned in.
The search is repeated every hour if an offline device exists.

Manually activate pairing mode

Depending on the device and power supply, there are different methods to manually activate pairing mode:

Battery powered with pairing button

Immediately after inserting the battery, keep the pairing button pressed for at least five seconds until the status LED indicates pairing mode.

e.g. Touch Air, Valve Actuator Air, IR Control Air, etc.

Permanent power supply with pairing button

Keep the pairing button pressed for at least five seconds until the status LED indicates that pairing mode is active.

e.g. Multi Extension, Nano IO, etc

Permanent power supply without pairing button

Switch off the power for 10 seconds, then switch it back on. If no connection to a Miniserver can be established for two minutes, then pairing mode is activated for 30 minutes. During this time the device can be paired.

e.g. RGBW Dimmer Air, Tubular Motor Solidline Air, Shading Actuator Air, etc

Wake up battery powered Air devices

Battery powered Air devices are typically in a low power state to save energy. They only wake up for a short time, e.g. when a value or button press is transmitted. For this reason, battery powered Air devices cannot be contacted by the Miniserver at all times, and therefore do not identify themselves when they are in low power mode.

To wake up a battery powered Air device, right click on it in Device Status and select Keep device awake:

When the device wakes up for the next time, it will stay awake for 5 minutes. To manually wake up a device, press a button or the learn button on the device, or trigger a sensor.

Once the device is awake, additional functions can be executed,
e.g. calibration run and device test, un-pair device, retrieve detailed device information, identify, etc.

By right clicking on the Air Base Extension in Device Status, you can keep all Air devices awake.

Update and diagnostics for Air devices

If an Update is necessary for an Air device, they are highlighted orange in Device Status. This often happens after a recent update of the Miniserver or when adding devices with an older firmware version.

The Miniserver automatically updates Air devices in the background, and it can take up to one hour.
The devices generally remain operational. However, there can be delays in communication. In rare cases, some functions of Air devices may not be available until the update is completed.

The following options are available for Diagnostics:

1. The Status LED of a device allows for quick error checks.
Red/green/orange flashing: Device is in pairing mode.
Orange flashing: No connection to Air Base/Miniserver possible.
Green flashing (continuous or 3 times, then off): Everything okay, Extension is online.
Quick red/green flashing: Device was selected in Loxone Config and is identifying.
Not flashing: Normal operation (the status LED is off or was switched off, depending on the device)

2. In Device Status, Air devices are listed along with details regarding signal strength and battery level.
