I have two identical single-family houses, each equipped with its own LogicMachine and TP1 KNX installation. Since they share the same project origin, they have overlapping individual addresses and identical Group Addresses.

Recently, both installations were unified under the same Internet router/network infrastructure (House A on 192.168.1.x
and House B on 192.168.2.x). I need to make sure that KNX telegrams from House A never leak into House B, while keeping ETS6 programming capability active both locally and remotely via ZeroTier (using IP Tunneling).

Before applying these changes, I would appreciate it if you could confirm my planned settings:

  1. House A (Screenshot 1):
    • Enable IP Routing: Disabled (unchecked)
    • Accept IP Tunneling connections: Enabled (checked)
    • Multicast IP:224.0.23.12

  2. House B (Screenshot 2):
    • Enable IP Routing: Disabled (unchecked)
    • Accept IP Tunneling connections: Enabled (checked)
    • Multicast IP: 224.0.23.13 (Changed from default just in case)

My questions:
  1. With Enable IP Routing disabled on both units, will this completely prevent group addresses from crossing between houses over Multicast/UDP?
  2. Will ETS6 IP Tunneling (unicast to each LM's IP / ZeroTier IP) still work reliably with these settings for programming individual devices on each TP bus?
  3. Is there any additional parameter or filter I should adjust in the LogicMachines?
Thanks in advance for your help!]]>

Last week, while working very quickly, I accidentally supplied a logic machine with more voltage than it should have.

Is it possible that the printed circuit board has a Zener diode or something similar that protects against overvoltages?

So that replacing it will make it work again?

Version: 20240426
CPU/IO: 0.28 0.45 0.64
Memory: 35%
KNX/TP: OK

CPU sometimes peaks to 1.5 without visible load.

There are 2 Modbus devices configured.
Polling was 10s, now increased to 45s, but lag still present.
Stopping several Lua scripts did not change behaviour.

Previous firmware worked perfectly on the same hardware.

Is there any known issue with KNX stack, scheduler or IO handling in SQ20240426?

Any ideas what to do?

I'm using a couple of "Schneider Wiser for KNX" controllers, which I know lack several firmware updates when compared to LM5 controllers.
I could not find any info wether or not the fimware of Wiser for KNX will be updated in a near future, or even if new HW versions are coming to the market.
Can admins from logicmachine confirm if something is moving to update the Schneider products or if they will no more be updated ?
Thanks for any info

All of my KXN power supplies have 30V output, but LogicMachine (LM5p2-KCD example) indicates 24V... it's 24 our a range ?
