I am trying to get shelly to work on my network but I seem to have multicast problems. The ubuntu 20.04 server where OH2.5.9 runs (standard apt, not docker) on somehow only joins multicast on a virtual docker0 network interface, not the default eno1 ethernet adapter.
I don’t receive the multicast messages from a Shelly DW2 which is two switching hops away.
A guess would be that this is because eno1 (which is connected to a switch port) is not joined to the multicast group and therefore not giving the correct IGMP responses.
Is there a way to tell the shelly binding or OH use a specific interface to join the multicast group on?
I can make all multicast packets appear on ethernet interface eno1 by manually adding the multicast address via sudo ip addr add 224.0.1.187/32 dev eno1 autojoin but somehow it does not seem to really help.
