Strange behaviour from IoT hub

Hi!

I have a RBK850 setup with latest firmware installed.

I have several HomeKit devices that work fine but having a strange problem with one.

I’m part of the beta test for Plejd https://www.plejd.com/

The strange part is that while connected to the router unit, all normal functionality works, but not HomeKit.
If I move the hub to one of the satellites it works, albeit temporarily.

I’m of course in contact with Plejd as well but so far we haven’t been able to figure out why it won’t work. Especially the fact that it intermittently works through a satellite but never when connected directly the router makes it hard to figure out.

      Connection between satellites is fine, at least according the router status page. It's about 15 meters between them. The hub is connected with ethernet.

    Is the "Hub" this product: https://www.plejd.com/products/GWY-01 ?

     

    This group of products appears to be networked entirely with Bluetooth (no WiFi), so the home WiFi system functions only to connect the gateway unit to (a) the internet, and (b) other devices within the local network, such as Apple HomeKit controllers.  Correct?

      Hi

      Yes it's that device and it uses Ethernet and Bluetooth. For "normal" non-homekit use, it can connect both through the Ethernet and Bluetooth, and both works (ie I can disable bluetooth on my phone and still connect).

      When I use HomeKit I believe it uses ethernet.

        The forum often has posts regarding Apple HomeKit. (A mystery to me as I do not have it.)

         

        Could you expand on this statement from the first post: "If I move the hub to one of the satellites it works, albeit temporarily."

         

        Would there by chance be any Ethernet switches in this network?  There have been issues with IGMP Snooping where media servers would work when connected to one part of a network, but not when connected to another part.  I suspect the technology Apple uses to keep HomeKit (controllers? servers? masters? - what are they called?) informed about devices on the network that can be controlled.
