Sleep issues

I would suggest to create a Middle of The Night activities area, which could include Lego bricks, books, colouring projects and physical puzzles to put together. Yoto: https://uk.yotoplay.com/ is a good device with just music, so there are no screens. 

There are a few factors that may or may not contribute.

LEDs. According to this article, they play a profound effect on health and sleep/waking cycle: https://www.industrytap.com/french-agency-says-led-lights-can-cause-irreversible-damage-to-the-eyes/48861"According to a report by the French Agency for Food, Environmental and Occupational Health and Safety (ANSES), LED lights can irreversibly damage the retina and wreak havoc with natural sleep rhythms. ANSES even warned powerful LED lights to be ‘photo-toxic’."

A good alternative is to have a few Natural rock lamps covering the LEDs in her room plus one halogen lamp + bulb. These are legal for those of us with light sensitivity: lightaware.org

I would ask her GP about taking her off melatonin. It can be damaging long-term. Other contributing factors to Autistic and ADHD children will include:

A hyper-active brain puzzle-solving and trouble shooting Unresolved Events or Encounters, Philosophical inquiry, Big ideas and exciting calculations. It's important children are allowed to express and talk through as best they can everything they are thinking about or it will become a backlog and build into overstimulation and overwhelm.

A hyper-imagination. Wild dreams, vivid nightmares and such. So long as the content is mystical and not actual redirecting their thoughts to something they encounter in their imagination as soothing can help. 

ADHD children might need less sleep. It could be good to set something up for them to engage with when they wake such as noted above, again, with salt rock lamps and a halogen so they are not being given daylight doses of artificial light which will send signals to the brain it's time to wake up.

A lack of exercise. Children need to exhaust their imagination, their thoughts and also their physical being. Yoga stretches at night are quite useful. Jumping jacks are useful in a pinch.

And then of course diet can contribute. Either an unknown allergy causing discomfort like gluten/grains/milk or too much sugar/caffeine (such as in chocolate) in the evening.
