Glamox Connect will warn you about devices missing by giving you a fault. It is important to note the difference between device missing and device not responding.

The golden rule for a device missing fault is Investigate in local system. |
Device not responding:
Glamox Connect still get the device from the local system through the gateway, but it is not communicating status and responding to requests from Connect
Device missing:
Glamox Connect do no longer get the device from the local system. There are multiple cases where this could happen, but the common factor is that it needs to be investigated in the local system.
We can categorize the cause of Device missing into the following, general categories
Device is broken
In most cases this will NOT give a device missing fault in Connect.
But there are situation where this can happen, typically if the device is broken and gateway has been reconfigured while it is broken. Example can be if the device is broken in Ethernet2DALI and the bus for some reason has been cleared and re-adressed
Device is removed from local system
If the local system has been reconfigured and the device has been removed, the device will NOT be automatically be removed in Glamox Connect. This is to prevent unwanted loss of history.
If the device has been intentionally removed from local system it either needs to be removed or replaced Connect - Replace device in Glamox Connect
If the device has been removed unintentionally it needs to be re-added in the local system according to the system specifications. If the device is being re-added to the same gateway as before it is likely that Connect will detect this and the fault will be closed automatically.
If the fault persists, please check to see if Connect has discovered the device as a new device. If this is the case, replace the faulty device with the newly discovered device by following Connect - Replace device
Device has been reprogrammed or moved
In some cases if the device has been reconfigured in the local system it can be detected as Device missing in Connect. This most often happen is the device is moved to another gateway and Connect is not able to detect the change.
One example is if you have multiple access points and move a device to a different gateway.
If both gateways are on the same access point a race condition can occur where Connect is not able to update the parent gateway as both gateways are reporting a different state. When this is the case you will NOT get a new device as well as the fault not getting resolved. In this case the existing device needs to be removed for the new device to be discovered
If the gateways are on different access points you will probably get a new device linked to the new access point due to the limitation of traffic between the access points. If this is the case the device needs to be replaced by following Connect - Replace device
Report to LMS support
There can of course be corner cases that we have not yet discovered!
If you are experiencing Device missing faults and you feel that it is not covered by any of the cases above, or that you feel that there is no reason for Connect to report this as Device missing, please report this to Glamox LMS Support
