ESP8266 UP switch

thingiverse

New Version: http://www.kratzer.it/lichtschalter.html (apologies, only in German) Smarthome mqtt switch with 4 touch buttons and one or two rgb LEDs. This switch fits Busch/Jäger standard programs. However, you can print custom covers for your switch system. The ESP SW is available at https://github.com/hexxter/ESP8266_UP_switch. You can use the switch as a replacement for an original mechanical switch, but it has 4 buttons and only one 220V 5A power switch. I use Button1 as an Alarm and to turn on lights around my house. Button2 turns on the main room light over the power switch. Button3 turns on an indirect light (white) and Button4 enables my rgb light. For Button3 and 4, I use this box: http://de.aliexpress.com/item/RGBWW-Strip-WiFi-Controller-1-Port-Control-200-Lights-Communicate-with-Android-Phone-Via-WLAN-to/32502007408.html I use mosquito as an mqtt broker with home-assistant.io as the backend. The BOM includes: Powersupply: http://de.aliexpress.com/item/5pcs-AC-DC-85V-265V-700mA-Isolated-Switching-Power-Board-Module-Industrial-Power-Supply-Built-in/2054274081.html Touch (see pictures, you can solder some metal on the edge pins; I use chopper wires for touch field): http://dirtypcbs.com/view.php?share=15460&accesskey=1b1a437a41eb1534f14b488f33c2cf78 http://de.aliexpress.com/item/5PCS-TTP224N-BSB-TTP224-SSOP16/32432360351.html http://de.aliexpress.com/item/WS2812B-4pins-5050-SMD-W-WS2811-Individually-Addressable-Digital-RGB-LED-Chip-FREE-SHIPPING/1594023008.html You can glue abstandsrahmen_touch_pcb.stl on the bottom side of the touch pcb for better isolation to the metal plug frame. I use ds18b20 for room temp. The ESP8266 is cut into 2 parts (see pictures); you must bridge GND and one IO to the 220V switch at http://www.esp8266-projects.com/2015/04/p2-wifi-web-power-switch-for-mains-mpsm.html
