The SonDek - A Sonoff Powered Decora Light Switch

thingiverse

This is an original design of a decora style light switch that can house a Sonoff Basic WiFi Smart Switch. It is a drop-in replacement for any standard or decora light switch. It consists of a 3D printed decora light switch body and switch paddle/face with a Sonoff basic board that slides into the printed switch body. I highly recommend that you cut out the screw terminals and solder some short wires directly to the traces. The screw terminals do not hold the wire in very well and there is very good chance that the wire will slide out and short on your box. Use the pin of a pop rivet to hold the paddle to the body. The holes may be just a little undersized so you may have to put the pop rivet into a hand drill to ream out the holes in the body and the paddle first. If the inconsistent glow bothers you try adjusting the LED on the board and put a small piece of heat shrink around it to focus/shield the side light. See the last 4 photos for the heat shrink tube mod. Lights (or other loads) connected to the SonDek can be controlled by the physical switch or with an App, Google Home, Alexa or Apple Home. If you flash the Sonoff with something like Tasmoto you can also control it with a web interface, MQQT, Home Assistant, NodeRed, Hue emulation, Wemo emulation and many others. Designed from scratch in OpenSCAD with at least 20 incremental versions to get to this point. CAUTION. You are working with line voltages here so be certain you know all of the safety precautions. I will not be held responsible for you burning down your house. **2018-11-28** Uploaded version 6.08 of the body which includes some incremental improvements. Thanks for the feedback Ralph.
