Administer through a Web Browser
Every router that I've worked with has had a web UI. The fact that I can administer our eero network only through the mobile app is inconvenient and limiting. Additionally, my wife set up our eero but when I went to set up the eero app on my Android device, the setup procedure did not graciously take into account that the network is already tied to an app. The eero network needs to allow for more than one connected app.
While i do understand not having a web UI has security benefits, recent destruction of my smartphone has left me unable to block/unblock devices my son uses. To turn on devices i was manually blocking, I had to install the app on his phone since no web UI. Now he can turn on his devices anytime, even family schedule devices, hence the wolf is guarding the hen house. I will have to change the password when i get set up on new phone but would have been nice to gain control of my eero without having to set up the app on his phone.
