Daylight mode in Lake Controller is initiated in the software.
Whilst Lake Remote does not have daylight mode in the same way as Lake Controller Apple iPad does have Accessibility Options that allow high contrast settings.
To enable these do the following:
Settings > General > Accessibility > Accessibility Shortcut > Invert Colors
This now sets the home button into a toggle invert colors mode activated when you triple-click it in fast succession.
To enter Invert Color (daylight mode) triple-click the home button 3 times (you can be within the app when you do this)
To leave Invert Colors (daylight mode) triple-click the home button 3 times.
