KNX -> SP112 tasmota -> stops working after a while - IGMP issue?

[Zaschii]

PROBLEM DESCRIPTION

usually same issue then in this old topic #5425.
I have 2 Gosund SP112 plugs, flashed with tasmota 13.2 knx version.
Both plugs have the same problem.
On our MDT Glastaster / KNX switches we have buttons to switch this tasmota plugs on / off directly via KNX.
Everything works for a while (few hours)... then the switch works only sporadically. It seems that packages are lost.
if i then unplug the socket and plug it in again, everything works again for a while.
or wlan is based on unifi ap which are connected per poe in a zyxel gs1900 poe switch.
in this switch and in unifi igmp v3 and igmp snooping is activated.

Sadly to say there a lot of devices which have a not reliable working IGMP implementation.
Have you checked if the packets are still transmitted?
Tasmota KNX can't work when packages are lost / not sent / dropped.
Sorry without more detailed info where can be seen that packages are arriving correctly we can't help.

[Zaschii]

igmp as cause is just a assumption from my side.
i can see that the group adress is correctly sent on the knx bus.

I tried a multicast tester app and if i hit the knx button i see some cryptic values in this app - so iam not sure what happens with the packages.
How can i track the traffic effective? maybe with ntopng?

Maybe this helps https://gist.github.com/friek/6c10535b2e43f0e0867ce21b0679a337 to test.

To monitor wifi traffic with Wireshark is tricky.
