The HA SwitchPlate is a user-programmable LCD touchscreen you can mount into a standard North American work box in place of a light switch. It connects to your home automation system over WiFi to send and receive MQTT messages in response to user interactions on the screen or events happening in your home. The result is an attractive and highly-customizable controller for your home automation system which you can build yourself!
The HA SwitchPlate ("HASP") utilizes a Nextion 2.4" LCD Touchscreen display mounted in a 3D-printed enclosure as a touchscreen panel for home control and information display. An ESP8266-based microcontroller provides WiFi connectivity and system control. The project has been developed to integrate with Home Assistant but should be compatible with any other MQTT-enabled automation platform such as OpenHAB, Domoticz, Node-Red, Wink, SmartThings, Vera, HomeKit, etc.
This assembled unit is still considered beta - several users are now running this system in their homes and I believe any major bugs have been identified and addressed, but there may be minor changes to the software over the next few weeks as users continue testing. Updates to the software components can be downloaded by HASP from GitHub automatically so applying new software features and fixes should be easy.
The assembled hardware is only part of the overall solution - you will need an automation platform that can send and receive the appropriate MQTT messages for this device to do much for you. The project includes extensive automation examples for Home Assistant, but one will need to be able to modify the examples provided in order to make this device fully functional in your own environment.
The hardware design as presented here should be complete. Source files for everything included can be found on the GitHub repository and I strongly encourage users to try building their own - it's a fun project to build and complete build documentation is provided! Still, it does require some special tools and I'm hoping to build a handful to help those out who may not have the hardware experience or access to tools to try this device out.
This device is 3D printed on a well-maintained Prusa I3 Mk2.5 and the results are pretty damn good. The front surface of every unit will be smooth and high quality. Rear surfaces will be printed at higher speed with slightly lower quality as they will live their life buried in your wall. The end result isn't quite injection molded, but it's close and it should look great on your wall.
The complete Bill of Materials is available along with links to each product to build your own. Each HASP costs around $35 in raw materials when purchased in large-ish quantities. Building a single device will be closer to $50. The $65 price tag here covers shipping and my time to hand-assemble each device.

Hi! My name is Allen and I've been designing open hardware solutions then sharing the resulting project designs. I've setup this store to offer assembled versions of some of my work to folks who might be interested in trying things out without access to the tools or skills required to manufacture the finished project.
You'll find complete source code for all hardware and software linked within each page, so please do feel free to skip buying stuff from me and go make your own! I'm far more interested in people learning how to design and build things than I am in the couple bucks of profit I might make from any of this. Still, I recognize that it may not be practical for everyone to recreate the work but may find value in the finished project, so after several requests I opened this here store to fill that need.
Feel free to shoot me an email if you have any questions!
