My Google Nest Mini was working with Habitat just fine. I changed my router and network name and added both the Habitat and the Nest Mini back with fixed IPs to the new setup.
In my phone google home app I can see the habitat devices I have allowed Google access to and can control them through the Nest Mini and the App.
However, on the Hubitat side, in Chromecast Integration (Beta) when I run re- discover it does not find the nest mini. I deleted the Chromecast app and reinstalled it but that did not help.
