esp8266-google-home-notifier

Send notifications to Google Home from esp8266.

This library depends on Google Translate Service.

This is the Japanese document on Qiita.com;

Install

This library can be installed from the Library Manager on Arduino IDE

Requirement

• Arduino board

  • esp8266 *Arduino Core ESP8266 2.x only
  • esp32
    (note: 1.0.2 and later, and 1.0.4 requires 83810fa or later of arduino-esp32)

• esp8266-google-tts
  download from Library Manager of Arduino IDE

• (only for ver 1.0.1 and earlier) Latest ESP8266mDNS

  • download ESP8266mDNS.cpp/.h to $LIBRARIES_DIR/esp8266-google-home-notifier/src/ and restart Arduino IDE, like below structure.

  or

  • use Arduino Core for ESP8266 2.5.0, which will merge ESP8266mDNS.cpp/.h, or later.
    -> The PR wasn't merged, so MDNS handling in this library should be fix under ESP8266 cor 2.5.0 or later.
