Thanks. I’d seen this in the HA documentation for the HomeKit integration but there’s no way of disabling this on my broadband router (Virginmedia SuperHub3). There are reports in the Virginmedia forums of other products (not related to HA, HomeKit or even Smart home related) having issues and also putting this down to IGMP Snooping but Virginmedia support say their hubs don’t do anything with IGMP snooping hence why there’s no settings to enable/disable it.
One thing occurred to me is my HA is connected over wireless (RaspPi) and Home App on my iPhone obviously connected wireless. I was wondering if this is related somehow to wireless networks but not sure what.
I thought also maybe the docker container config might be the cause but my HA container is running on the HOST network (so has direct network access) and not on the docker bridge network.
One other question (which isn’t related to the “No Response” issue).
When you add HA to the IOS HomeApp Is suspect it finds it on the local network. What happens when you leave home and and connect back to HA externally?
Is the HomeApp aware of this?
I haven’t got this far as yet due the the “No response” problem.
