Multiple multicast addresses - Simuzer - 26.10.2025
How can I add multiple multicast addresses to only one logic machine?
Multicast Address:
- 224.0.23.12
- 224.0.23.13
- 224.0.23.14

This is not possible, what are you trying to solve?

Each block has an average of 18-20 floors.
Each block has an average of 20 floors. Each block has two main lines.
Below is an example physical addressing for block A1.

Blocks and knx physical addresses are as follows. As you can see, there are 3 addresses from 1.x.x. (red, blue and green). But IP Router IP addresses and group addresses of all devices are different.
i have only one Logic Machine..
Can't I solve this with 1 LM? Or do I need 3 LMs for 3 regions?
I hope I was able to explain it. I'm looking forward to any suggestions you may have.

How many group addresses is all this? What is the task for LM on this project?

A total block will be around 600-1000. Therefore, the total maximum will be 12000-17000 group addresses.
The LM's job here is to monitor and turn lamp states on and off. It can also change sensor times.
LM's tasks:
- Monitoring lamp status
- Controlling lamp on/off
- Changing regional sensor timings when necessary
RE: Multiple multicast addresses - Daniel - 28.10.2025
You need at last 3 LM to have 4-5k objects per each. If you need some global scheduling/settings you can use MQTT to communicate between LMs. How is the network done? KNX IP works only on one subnet.
