So you would need two SmartApps to cover all your scenarios.
This one - Ultimate Mode Based Thermostat which allows you to set temperatures while in away mode or other modes.
For regular scheduling you should use the 5-2 Day Thermostat which allows 4 schedules per day for the weekday and weekend. Just set the modes you want it to operate in, e.g. home and night.
