Can someone bug/hack your home network and take control of electronics connected to it?

Scenario

Basic home network setup, typical router/modem with WPA2 pw setup. No other protection or anything else setup.

Is it feasible/possible to hack someone’s network or setup an unauthorized network and take control of any electronic device that connects to it?

If so, could someone turn a phone or ipad into an audio device and use that to record or spy on someone?
