Do you know the temperature in her room? You need a thermometer in her cage so you can make sure the temperature is staying warm & steady enough.
It's normal for hedgehogs to sleep during the day, as they're primarily awake at night. It's also normal for them to not be active while being watched - most won't come out with lights on or anyone moving around the cage. So you may not really actually see her being active, just the aftermath.
Do you have a wheel for her? Can you tell if she ran on that last night? Eating & drinking is good.
