2. There will be no new entity or device found

@rezmus Thank you for your useful information. By testing, my Xiaomi_gateway3, Zigbee devices, and BLE devices are all successfully connected to HA.
Additional information: If Xiaomi_gateway3's firmware is v1.4.4_0003 (factory firmware) , please update once to make sure your gateway could working with ha and MiHome APP simultaneously!

I have similar problem: [homeassistant.components.xiaomi_miio.gateway] DeviceException during setup of xiaomi gateway with host 192.168.1.IP with lumi.gateway.mgl03 gateway.
I'm using AlexxIT's component for Xiaomi Gateway 3 integration but I was counting that Xiaomi Miio will handle alarm modes (these features are not available in AlexxIT integration at the moment).
