If you have an Android device, the location must be activated so that you can see lights.
Several causes can be considered:
1. the light is not transmitting because it is in emergency mode. This is the case when the green LED is off (power failure).
2. the light is not transmitting because the radio module is not plugged in correctly.
3. the lamp does not transmit because the radio module or another part of the electronics is defective.
4. the luminaire has already been associated and is already included in this or another project.
5. the luminaire is transmitting but is too far away.
6. the luminaire is transmitting, but there are other luminaires between the luminaire and the position of your end device, over which the communication would run. Communication are not in transmitting mode, so the network is interrupted.
Remedy:
1. check if the luminaire is transmitting:
Check at the luminaire to see if it is in emergency mode (cause 1. above).
Locate the luminaire directly with the terminal device and establish the network connection.
The luminaire should now be visible.
Add luminaire should now be visible. If this is not the case, then tap on "Network connected" and check whether the
luminaire is displayed in the list of alternative connections (wait for the list to build up). Connect directly to the luminaire
and try again.
2. If the light does not transmit, check causes 2 and 3.
3. If the luminaire transmits, check cause 4. The luminaire is probably already associated if it is not found when it is
The light is probably already associated if it is not found when adding, but is displayed in the list of lights when selecting the connection.
4. check causes 5. and 6.
In the case of 5. there is a permanent network fragmentation.
In the case of 6. the network fragmentation is temporary and the luminaire should be available again after the tests of the other luminaires are finished.
The meaning network fragmentation:
The luminaires do not form ONE contiguous network, but form into two or more separate networks because of too much distance between them. You can check this by getting close to individual of the missing luminaires and establishing a network connection with them (see tip "Selecting a connection" in the previous section). If you are dealing with several separate networks, you have two options:
• Manage all luminaires in one project anyway. To do this, place your terminal device one after the other at a
location from which you receive each subnetwork, and perform the commissioning from there. Do not be disturbed by
"Communication error" messages that are likely to occur then. Manual test execution and status query
must then also take place in such "stages".
• Manage luminaires network-wise in separate projects. To do this, create a separate project for each subnetwork
and perform a separate commissioning for each project.
