Hello.
It's been a while.
As per your advice, I am considering placing KNX devices on separate lines.
I'm thinking of creating it in the format shown in the attached image.
I intend to import only the group addresses related to each line into each LM as a single ETS project.
I would also like to know how to set up the KNX connection in the LM's system config when using it this way.
I would appreciate it if you could tell me if the following usage is physically possible and, if possible, how to do it.
① Write a value to the group address in the LM in Line 2 using the event script in the LM in Line 1
② As mentioned above, how to send and receive data between LMs when the two LMs are connected only by IP
→ I expect this is possible if you use API, MQTT, etc., but I would like to know if there is a good way that is possible only between LMs in the same network.
③ If I want to use only LM1 (placed on Line 1) as the LM used as the API and MQTT interface, how should I design it to monitor the status of the group address on the Line 2 side and send commands from an external server?
Both of these concerns are things I would like to consider in order to achieve my goals of distributing the number of KNX TP telegrams by dividing the lines with LMs, and, if possible, limiting the number of LMs that send and receive data with the outside world using MQTT etc. to just one.
I would appreciate any advice you could give me.
