Manual control still matters
A light switch, button or normal thermostat interface can be more inclusive than app-only control.
Shared permissions need boundaries
Give people the access they need without unnecessarily sharing owner-level credentials.
Naming should be obvious
Room and device names should make sense to everyone.
Automations should not surprise people
A routine that is clever for one person can be confusing or disruptive for someone else.
Keep in mind. Compatibility is not permanent. Confirm the current manufacturer, platform and certification information before purchasing, resetting or migrating a device.
