door_transmitter
Description: Transmits door open/close state to Adafruit IO (cloud)
Sources
- ESP8266 Arduino from: https://github.com/esp8266/Arduino
Target
- tested on Adafruit Feather Huzzah 8266 https://www.adafruit.com/product/2471
- reed switch with NO and NC
Revisions 05/15/18 - fork from Adafruit IO door tracking example (https://learn.adafruit.com/using-ifttt-with-adafruit-io/), Written by Todd Treece for Adafruit Industries. MIT license, all text above must be included in any redistribution - removed EEPROM code - switched to ESP.DeepSleep(0) and sensor driven wake from deep sleep - fixed bug in example code related to 8266 DeepSleep (seconds in exponential format) 10/17/18 - reverted to original example code (wake at x second interval) to capture both open and closed door states without additional hardware 10/21/18 - code cleanup - fixed battery code
Feature Requests - 10/20/18 - move IO feed name from code to config.h
