Put controls where actions happen
A bedside or entry button can be easier than opening an app.
Use clear labels
Multi-action buttons become confusing when nobody remembers what each press means.
Keep basic manual control
Critical everyday functions should not depend on a complicated automation.
Battery and connectivity still matter
Wireless buttons need the same maintenance discipline as other sensors.
Keep in mind. Compatibility is not permanent. Confirm the current manufacturer, platform and certification information before purchasing, resetting or migrating a device.
