Every time I want to add an IoT device, such as a thermostat, to my network i run into tons of trouble, because invariably I have to use an app on my phone to add and configure it and they are always on the 2.4g network and my phone is on the 5g so it fails. I have sometime succeeded by leaving the house and once far enough away my phone drops to 2.4g and yelling back and forth with my wife manage to get through the setup. What a PITA! If only there was a button in the Eero App to pause, i.e. temporarily disable, the 5g band on my entire network for something like an hour so I can get through everything before it automatically comes back on.
