Smart Plug features

I need to know if the smart plugs support integrations with:

  • Smart Life app
  • SmartThings app

Also do the plugs

  • have a vacation mode, or random start and stop time around a specific set time
  • have the ability to set the status of the plug after a power failure, i.e. set to:
    • turn on
    • turn off
    • use last state before power failure, OR
    • reverse the last state before power failure

Thank you in advance.
