I have a fan, a light and two sonoff basic devices to control them. As sonoff can only work with internet, I thought it would be a good idea to be able to fully override the controls with separate switch just in case.

Diagram for connecting sonoff Basically, I want to use three separate switch.

  • if only S2 is on, the state of the devices will depend on sonoff
  • if S1 is on the light is always on
  • if S3 is on the fan is always on
  • if all three switches are off the devices are always off

I am aware that the button on sonoff can be used to override. However, I will be concealing the devices as they look a bit ugly while exposed.

I want to know if this setup is safe and will work without burning anything up.
