Changing track here a little bit - with Google WiFi - it's nice that we have Android and iOS apps to configure the Google WiFi platforms, but oddly enough, there doesn't seem to be a way to manage the Google WiFi devices from a Chromebook (at least those that do not support the Google Play Store to download and run Android apps)
@thiggins - can you check with the Google POC and perhaps they have some idea on how to do this?
(One might have a family member that just has the google router and chromebook, so no way to run an app...)
Not a complete self-service solution for folks without an Android/iPhone, but the Google Wifi app does allow more than one Google account to be associated with the Wifi device allowing for remote Wifi management: https://support.google.com/wifi/answer/6180940?hl=en
So if your family member is comfortable with giving you some remote management control, you can come over to set up with your phone and then administer their network from home after that. I plan on doing this after setting up things with my parents.
