Wiring

I don't have any diagrams handy but you just need a switch between D0 and Ground and a pullup between D0 and 3.3v.

Known Working on...

• Wemos mini D1 knockoff https://amzn.to/2VX5C09
• NodeMCU https://amzn.to/2SZWLJ6
• Adafruit Feather Huzzah https://amzn.to/2MfymN9

Installing

Right now this needs Arduino/esp8266, Homie 2.0 and its web assets on the spif. tl;dr - If anyone actually had interest in a binary they could burn on I would be happy to provide it.

ToDo

Maybe move away from Homie to something that supports HASS's MQTT detection. Unles someone makes a HASS plugin for Homie.

Example of using with HomeAssistant
