DIY In-Wall Sonoff Light Switch

thingiverse

This is an old version. Please see version 2 of the in-wall sonoff light switch. Version 2 doesn't require the additional pcb and button. You can find it here: https://www.thingiverse.com/thing:2632463 After printing, you will need to insert the Actuator through the back of the Mount Plate and **carefully** force the tabs of the Actuator into the holes on the Mount Plate. Once you have the Actuator installed, it will be a little stiff and hard to move, but just work it back a forth a few times and it will soon operate smoothly. You will also need to make up the PCB that holds the pull-up resistors and buttons which the actuator presses. I just used some perf-board and salvaged buttons and resistors to make it. The PCB should be shaped as in the image above because the sonoff's button and LED are rather tall and I wanted to make sure that the whole switch enclosure would fit inside the wall with the existing wires tucked behind it. Below is my video describing my Sonoff In-Wall Light Switch. I also show how to install it in the wall, by replacing an existing light switch. One thing to note, the sonoff will **not** be able to replace a 3-way light switch, I explain this more in the video. I debated uploading this to a different site and charge $1 to download it. But ultimately I decided against that, as I am a big fan of open source and have benefited from it so much. So instead of paying for the .stl files, I would appreciate it if you would subscribe to my new youtube channel and share the video. https://www.youtube.com/watch?v=XgzF7lwwa0A&t=49s
