decor switch housing for ESP relay

thingiverse

I built this to replace a Honeywell timer switch that gave out. Check out the post with instructions for the build at http://homeautomation.proboards.com/board/4/openhab-esp8266-wifi. Background: I started with Eric Tsai's Instructables post (https://twitter.com/Eric_1100), where I found inspiration in DIY home automation. Computourist (https://github.com/computourist/RFM69-MQTT-client) cleaned up the programming and added the ability to send to end nodes. Then, I found a great forum that simplified the build and offers a fantastic community at http://homeautomation.proboards.com/post/2053/thread. This is my attempt to give back to the http://homeautomation.proboards.com/ community. High voltage power supplies pose a significant risk of serious injury if not used in accordance with design and/or use specifications, if used in applications on products for which they are not intended or designed, or if they are used by inexperienced or unqualified personnel.
