Integration of google wifi in home app is the most disappointing addition. Unlike voice integration of all my devices in home app, i hardly use one they all are set. But with wifi you need an dedicated app that provides intuitive experience. On my google pixel 5 with latest home app, i have 3 google routers across my home connected backhaul network via lan. Not sure if it is a bug, i cannot see my main router online in the app even though it is online and my network is up and running.
