ESP8266 project to perform custom actions when pressing an amazon dash button
I bought a bunch of amazon dash buttons when they were on sale at 1.99€ each and wanted to trigger custom stuff when pressing on one of them.
You have to configure network settings of your Amazon dash button to use the same LAN network than your ESP8266.
Right now it only allows for 1 dash button.
Make sure you use the 1.4 Prebuilt / 1.4 Higher Bandwidth variant of lwIP.
My setup:
- Amazon Dash Button - 4.99€ on Amazon.fr
- WeMos D1 Mini - 2.80€ on AliExpress.com
