Proposal

Add an additional attributes called current_action and next_action. These attributes would displays the action based on current_slot and next_slot.

This way custom sensors can be created based on the attributes. I.e. is the scheduler currently active (slot is other than null) and if so what is it doing (current_action). Or create a sensor is always off unless scheduler is running a specific action...
