Pat the chicken wings completely dry with paper towels to ensure the skin becomes as crispy as possible.
In a small bowl, whisk together the baking powder, smoked paprika, garlic powder, onion powder, sea salt, black pepper, and cayenne pepper.
Place the wings in a large bowl and toss thoroughly with the spice mixture until every wing is evenly coated.
Arrange the wings in a single layer in an air fryer basket, ensuring they are not touching to allow for maximum airflow.
Air fry at 400°F (200°C) for 20-25 minutes, flipping the wings halfway through, until the skin is golden brown and blistered.
While the wings cook, whisk together the non-fat Greek yogurt, lemon juice, and dried dill in a small ramekin to create the dipping sauce.
Transfer the crispy wings to a clean bowl, drizzle with the sugar-free BBQ sauce, and toss gently to coat before serving immediately with the yogurt dip.
