How do I get my puppy on a proper potty routine after moving?

I recently moved from a high-rise apartment to a ground-floor place. When my puppy was younger, she was trained to use a grass patch on the balcony and would press a button to go outside. She basically had free access to potty on the grass patch when needed.

Now that we live downstairs, I can take her out properly for potty breaks. The issue is she has no consistent pee/poo routine. She goes at random time (press the button at night several times)

and I can’t find a clear pattern. Sometimes she presses the button just to go outside, does a tiny pee, and then just wanders around.

We also moved recently, so she’s still adjusting, and her appetite has been a bit off.

I’d like to transition her into a more structured routine (e.g. predictable morning poop, scheduled potty breaks instead of random button presses).

How do I shift from “free access grass patch” to a proper potty schedule without confusing her?

Any advice from people who’ve retrained routines after a move would be appreciated.
