There's a Python library that has been quite reliable for me for local control.

  $ python3
  Python 3.12.4 (main, Jun  6 2024, 18:26:44) [Clang 15.0.0 (clang-1500.3.9.4)] on darwin
  Type "help", "copyright", "credits" or "license" for more information.
  >>> import pywemo
  >>> d = pywemo.discover_devices()
  >>> d
  [<WeMo Switch "Guest">, <WeMo Switch "Fireplace">, <WeMo Switch "Bedroom Dresser">]
  >>> d[0].model
  'Belkin Plugin Socket 1.0'
  >>> d[0].toggle()
