ESP8266 IoT Wifi Button

thingiverse

Update: I've uploaded the Fusion360 File, allowing everyone to edit the button to their needs. A Super Simple IoT Wifi Button with ESP-08S Module is now available. This wifi button consists of just a few components: * ESP-08S Module * CR2 Lithium 3V Battery * 2 Battery Contacts * 2 Buttons * A 3D printed case BOM: * ESP-08S - https://eckstein-shop.de/AI-Thinker-ESP8266-ESP-08S-New-Version-Serial-WIFI-Wireless-Remote-Control-Modul * CR2 Lithium Battery - https://www.ebay.de/itm/10-x-Batterie-CR2-Duracell-Ultra-3V-Lithium-Duralock-DLCR2-ELCR2-ohne-Blister/401123887924?hash=item5d64d8cb34:g:coYAAOSwQwdakAhz * Battery contacts - https://www.luedeke-elektronic.de/advanced_search_result.php?keywords=5205&inc_subcat=1&pfrom=&pto=&fl_unavailable=1 * Buttons - https://www.ebay.de/itm/THT-Taster-6x6x7-mm-4-Pin-Kurzhubtaster-Drucktaster-Print-Schlieser-Draht-6-6-7/112627335689?hash=item1a391cc209:m:mfhBEF-tXFnpI_CgiJSu48g Software: The ESP8266 is programmed with the Arduino IDE. After a reset, it sends either a webhook (http get request) or an mqtt package to your smart home. It then goes into deep sleep. Both versions can be updated over an OTA web server (second button).

Thanks to AndyW83 for the initial design of the button, and also for programming the mqtt version for the button.
