Now that Wired backhaul is supported with the latest BE800 release I have been able to successfully engage EasyMesh with my BE800 as the main router and a BE550 as the Satelite router.  It does not seem that the IoT network is extended to the Satelitte router, only my main Wifi 2.4/5/6Ghz networks.

I have a good number of devices that I have been running on the 2.4/5Ghz IoT network.  These are things like my network cameras, WiFi enabled Smart Lights, my smart appliances, etc.  In total I currently have 55 wifi devices and 36 of them are on the IoT network.  This results in nearly all of my devices connected to the BE800 which makes for less than ideal wireless connectivity to the IoT devices which are on the other side of my home.  Is it expected that IoT networks will only function on the main router and are purposely excluded from EasyMesh?  I suppose that I could stop using the IoT network and move 55 devices back to my main Wifi SSID, but that defeats the purpose of segmenting the IoT devices to their own network for security purposes.
