In the meantime, a large number of compatible devices can be controlled via the Air interface and thus integrated into the building automation.
There are battery powered devices available for easy retrofitting as well as devices with fixed power supply.
Meshing and repeating
Loxone Air includes a meshing technology to interconnect the Air devices.
In this process, signals from more distant devices are forwarded to the Air Base Extension by Air devices with a fixed power supply, which work as repeaters.
This increases the overall range if a direct radio link from the Air Base Extension to more distant devices is not possible.
Note that communication via repeaters leads to time delays.
If an Air device requires more than two repeaters in succession, we recommend an additional Air Base Extension or Tree to Air Bridge near the low-signal device.
The number of hops (number of repeaters to the Air Base Extension) can be seen in the Device Status.
The Loxone Air communication is encrypted using IPSec. Each Loxone installation has its own encryption key.
The update of the Air devices is performed automatically in the background. The functionality of the device is maintained even during the update. When rebooted during the update process of the Mini Server or the Air Base Extension, the update will start again from the beginning.
The update may take up to an hour.
The versions of the device can be checked on the device status. If the field is highlighted in green, no update is necessary.
When multiple devices operating on the same frequency, the connection quality can suffer. Whether the channel you are using is free or occupied, you can check the Device Status of Loxone Config.
Open the device status with a right click on the Air Base and then select detailed device information.
The result is output in the file Report.txt
If the current channel is busy, the frequency of the Air Base Extension & Air Devices should be changed.
In the periphery tree right click on the Air Base Extension and then select “Change Frequency”.
In the bottom right of the pop-out the new frequency can now be selected. “Change frequency” By clicking on all Air devices are currently online about the change.
All Air equipment will now be converted to the new frequency, this is indicated by the status “online and changed”.
Finally, “Add to MiniServer” by clicking on the button to update the Config in the Miniserver.
Online Status of Air Devices
For all Air devices, the diagnostic inputs can be activated in the properties. You will find the Online status, which, as the name indicates, informs you about the current status of the Air device.
There are two reasons why an Air device from the point of view of the Miniserver can go offline:
1) No response from Air Unit
Loxone Air devices must acknowledge any data packet sent by the Miniserver (e.g a digital output of a Multi Extension Air is to be switched). The Airbase Extension repeats the transmission 3 times with delays of about 1sec, if necessary. After a total of 4 attempts have been made, the device is immediately set offline.
2) Timeout for the connection
Most Loxone Air units send a regular “keep-alive” signal to the Miniserver to report their presence and transmit some maintenance data. The Miniserver will set a device offline if it does not receive data for a particular period of time.
This timeout depends on the type of Loxone Air device:
- For devices which regularly transmit sensor data: 6x transmission cycle + 5min
- For voltage – compensated devices: 24h
- For battery powered devices: 52h
- For the remote Air: never
The Air units go back online immediately if the Miniserver receives any data from them. This includes responses to commands sent by the Miniserver. For example, an offline device can immediately switch to online if you try to change an output on the device, which allows the Miniserver to send data.
Note that the Miniserver does not regularly attempt to connect to an off-line device – this must be initiated by the device (see paragraph below).
Please note that the LED status display on the device itself can differ from the Miniserver. This is because the device displays offline (yellow flashing) when the Miniserver does not acknowledge its data.
This means that a device can immediately switch to offline mode by pressing a button and the miniserver can not be reached. The Miniserver can still hear from the device just a few hours ago and still shows the device as online (The Miniserver can not know that the device has tried to send something, and the timeout for the respective device has not yet been reached ).
Of course, a device also switches to offline mode, if the Miniserver does not respond to its messages after a few repetitions.
Devices that are offline are trying to reach the Miniserver on a regular basis to reestablish the connection. To avoid the air channel load and save the battery, the delay between the repetitions increases from a few seconds up to 24 hours. It can take up to 24 hours for a device to go online again. If any action (ie, touch or digital input) requires data transfer, the device will immediately try to go online.
