ESP8266 Making Google Home Speak

Using esp8266-google-home-notifier library on ESP8266 to make Google Home speak! Software Prerequisites/Limitations The GoogleHomeName must match the name of Google Home / mini setup in Google Home App. The ESP8266 must be on the same network as Google Home. MDNS: Dont include ESP8266mDNS.h supplied by Arduino-ESP8266. Internal ESP8266mDNS.h should suffice. Libraries required esp8266-google-home-notifier esp8266-google-tts WiFiManager (optional) GitHub: debsahu/GoogleSay sercret.h #define SECRET const char* ssid = "<WiFiSSID>"; const char* password = "<WiFiPassword>"; GoogleSay....

MeshyMcLighting: NeoPixels Lighting Solution Using Mesh Network

Wouldn’t be cool for many McLighting (RGB LED lighting using NeoPixels) to talk to each other and synchronize? Here is my naive attempt at this, which requires McLighting to be served as stand-alone web-client. MeshyMcLighting What is this? Wouldn’t be cool for many McLighting to talk to each other and synchronize? Here is my naive attempt at this, which requires McLighting to be served as stand-alone webclient. Features Uses painlessMesh to create mesh network and broadcasts state to every node Does not need WiFi connection to internet, standalone mode + mesh Web interface is borrowed from “WS2812FX esp8266” example, completely served on ESP8266 Can do minimal file upload to SPIFFs Completely Async!...

Talking to Twitter Using TwitterWebAPI for ESP8266

Idea: Use ESP8266 to talk to Twitter Get User Data or Tweet or Search Twitter Display the data on a Dot-Matrix display Implementation I created an Arduino library to talk to Twitter using its Web API made for ESP8266. There are other approaches like using a bearer token arduino-twitter-api, but comes with limitations in terms of not being able to send tweet. This Arduino library TwitterWebAPI can both search/read and post tweets....

Internet Connected Smoke Alarm

Have you wondered how to build a internet connected smoke alarm using ESP8266 and a cheap Kidde RF-SM-DC? Overall idea is to detect smoke alarm signals and send MQTT message. Home Assistant reads the MQTT message and sends out notifications that can be used to notify your local fire station. ESP8266 sends a MQTT message until the smoke alarm is beeping. Software Refer to to build the ESP8266 part of the internet connected smoke alarm....

Extreme Power-Save Mode: ESP8266 Powered ON After External Interrupt

Have you ever wondered how to turn on ESP8266 using external interrupt? Build a battery powered amazon dash button or a 18650 lipo powered door bell using ESP8266 without putting the device in deep sleep? Here is your answer. Idea Keep ESP8266 on OFF mode as default External 3.3V signal (can be short or long) arrives and turns ON ESP8266 ESP8266 wakes up and keeps itself awake until a task is perfomed Send MQTT data to server Put ESP8266 back to power OFF state Implementation RST pin is always HIGH/3....

Internet Connected Dog Water Bowl Sensor

Wouldn’t it be nice to know if your dog’s water bowl is empty? Let us build a sensor that measures the water level every 5 minutes. This value is sent to MQTT server and Home Assistant automation takes care of the rest. This sensor connects to MQTT and Home Assistant. See dogsensor.yaml for adding this to HA. Assumes that one has set up various notification sensors available in HA....
