When first installing the companion app (only tried on android, I don’t know if it’s the same on iOS) it defaults to the model name of my phone which automatically creates entities in Home Assistant. Then I have to go and change the name in the companion app settings and then change all the entity names in Home Assistant! Would be good if it asked for the name you wanted the device to be when first opening the app before auto creating the entities!
It’s the same on iOS. It’s uses your iPhone name
And I recall there being discussion for iOS app to allow customization of name as well back when iOS 2.0 app was in beta. I don’t think it ever got implemented
This feature did get implemented in the last few months (App Configuration → General → Device Name).
However it’s not part of the initial setup screen yet, which I agree would be helpful.
