Anyone tried installing a sonoff mini r4?

I pryed open my light switch but there only seems two cables that are white and black. I wish I could upload photos but I’m not sure if these are compatible with my sonoff minir4m. Anyone have tips?

  1. Not sure about that one particularly but I’ve had a whole bunch of sonoff installed in our rental no problems

  2. last I checked unless you had electrician’s license, doing DIY electric work was not legal and installing this chinesium stuff will most likely invalidate your insurance in case that stuff catches on fire.
