Hi
I am having difficulty finding the time to go experiment in any great detail, but, the 4 motion notifications are heard from the chime pro, and any connected phones, and it is easy to replicate, just install a ring doorbell 2 and chime pro on a Deco mesh network and your team will see it. I am unsure if my doorbell has had any updates but I switched on fast roaming, and no difference, so that bit seems to have been fixed.
