Sonoff iFan03 / iFan04 remote light switch cover mount

This model will let you mount a Sonoff iFan03 / iFan04 (iFan04-L, iFan04-H) fan controller remote control on top of a Decora-style paddle light switch. Keeping the physical light switch buried but available allows you to power cycle the fan controller if needed.  The remote mount is a snug fit so it stays in place, but can easily be removed and used as a remote.

A support mesh is required for the underside of the wall plate, but since it's not visible when installed, you don't have to do much cleanup beyond removing the support material.
