First of all, our customers like to be informed. We can set up home automation system so smart switch will indicate if door is closed or open. Switch color will change based on door sensor status. As a result, customer will know instantly if any door is open. If any door is open, top three LED indicators on smart switch will be flashing yellow color. If all doors are closed, top three LED indicators will turn solid blue. That is only one way we can visually indicate if door is open. Another example could be flashing lights or changing light color when door opens. We have more visual notification examples that can help people to stay informed.
