Alert manager app and alarms0 - ALEJANDRO - 21.05.2026
Good afternoon,
I'd like to ask a question, if possible.
I have an alert manager screen on a logic machine, and it needs to display all the alarms from that logic machine and three others.
Initially, I thought about creating standard group addresses using an ETS file, so that the LM_1 alarm addresses would be sent to the LM with the alert manager via IP.
The problem is that these addresses are empty; they have no data. What I'm observing is that the ETS group monitor is generating repetitions on the KNX bus, and I don't want those signals going to the KNX bus.
Is there any way to prevent these GAs from generating repetitions on the KNX bus, or is there a way for the virtual objects created on each LM to send data from one LM to another?
I don't know how to prevent the repetitions, and they are all happening in physical GAs that are empty in the ETS file, without any communication objects from KNX devices. Thank you so much

This is how KNX is designed, when LM sends telegram to a group and there is no knx device on the other end to receive it then by knx standard such telegram will be repeated 4 times as it waits for acknowledge to be sent.
We suggested you several times to not use KNX for communication between LMs but you rejected it each time.
In that case we cannot help you.
