Here I add WiFi LNK module to my ESP-TM2 Rainbird Irrigation System and add the Rainbird integration to Home Assistant. Once completed, I winterize the irrigation system for the coming winter.

Instead of sending data to services in the cloud, here we send sensor data to local InfluxDB database. Grafana is used to read data from InfluxDB and alert thresholds are set to send reactive alerts. InfluxDB Download and Installation: official docs Docker Download and Installation: official docs ESP32 connecting to WPA2-Enterprise Hardware ESP32 TTGo T-Energy SSD1306 OLED display BME280 sensor Software Dependencies Listed below are the dpendencies used by Arduino IDE, but use PlatformIO instead!...

Using ESPHome for connecting ESP8266 to MAX7219 Dot-Matrix Display to show useful information from Home Assistant. This is used by my wife’s channel Canvasyvibes Art Software: ESPHome

Install of Biobidet Bliss BB200 and connecting it to Home-Assistant. Wilbur Sargunaraj Software: ESPHome

Here we use ESP32 microcontroller to analyze real-time audio signals Real-time FFT to get frequencies Use MSGEQ7 chip to get the same data Display frequency bands on LEDs as bars FFT basics: GitHub: debsahu/ESP32_FFT_Audio_LEDs Libraries Needed Software FFT platformio.ini and Hardware FFT platformio.ini is included, use PlatformIO and it will take care of installing the following libraries.

Home Assistant Switch for 8 Relays: PCF8574 can be used to extend the GPIO of ESP8266/32 and here we use 8 ports of PCF8574 to control 8 Relay module GitHub: debsahu/PCF8574_8Relay Home Assistant Switch for 8 Relays Code can compile on ESP8266/32 PCF8574 can be used to extend the GPIO of ESP8266/32 8 ports of PCF8574 is connected to 8 Relay module Libraries Needed platformio.ini is included, use PlatformIO and it will take care of installing the following libraries....

An attempt to build a Amazon “Dash” type button to communicate with Home Assistant, which is a combination of two different projects GitHub: debsahu/TheButton Things we want to achieve: Low on power consumtion: ESP8266 is OFF when the button is not pressed debsahu/ESP_External_Interrupt Portable: Uses 18650 battery, lasts years Talks to Home Assistant: debsahu/HARestAPI ESP_External_Interrupt GitHub: https://github.com/debsahu/ESP_External_Interrupt HARestAPI GitHub: https://github.com/debsahu/HARestAPI

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....
