    I work with JSON mostly. So you might want to have a look at https://arduinojson.org/

  • GitHub repo WiFiManager

    ESP8266 WiFi Connection manager with web captive portal

    Project mention: Best Wifi provision for end users | reddit.com/r/esp32 | 2021-05-02

    I haven't tested it myself but here is an example library that appears to do this pretty simply.

  • GitHub repo esphome

    ESPHome is a system to control your ESP8266/ESP32 by simple yet powerful configuration files and control them remotely through Home Automation systems.

    Project mention: Introducing my TallyWhacker. A new smart home device designed souly to piss off my upstairs neighbor. | reddit.com/r/arduino | 2021-06-04

    Not OP, but I‘m assuming this is using ESPHome With it you can flash ESPs with custom firmware that you can configure through a YAML file. It uses MQTT to talk to HASS, usually mosquitto.

    Project mention: The operative system for a decarbonised, decentralised, digitised energy system | news.ycombinator.com | 2021-03-22

    When the physical layer of devices in the home don’t offer Wireless connectivity, hardware communication modules needs to be adopted to bridge the existing connectivity.

    This protocol exists already is called PJON: https://github.com/gioblu/PJON

  • GitHub repo espurna

  • GitHub repo IRremoteESP8266

    Infrared remote library for ESP8266/ESP32: send and receive infrared signals with multiple protocols. Based on: https://github.com/shirriff/Arduino-IRremote/

    Project mention: Making dumb LED strips smart. | reddit.com/r/esp8266 | 2021-04-21

    Your starter for 10 on ESP8266 and IR is crankoldgit's library When you say transistors I hope you mean big beefy power transistors or mosfets? The current led strips use can be surprising, my 4.5m RGBW 12V strip draws 9A at full brightness and the similar length WS2812 would pull 15A at full brightness if my software didn't restrict it. Do run the numbers on power consumption in regard to your switching device. It's possible to do what you want with the existing receiver but as you've already found it's not that straightforward and requires a good magnifier and enough knowledge of electronics to decipher the circuitry before you could modify it, If you want a reasonable size prebuilt RGB controller the generic H801 boxes are cheap, readily available, ESP based and easy to flash your own code to. The other possibility is to IR enable your ESP8266 using a simple IR receiver like one of the TSOP series, the filters and amplifier are built in and as it's just a 5mm package it's easy to mount it where it's convenient. That way you can have the option of IR or WiFi control, I occasionally use an old IR remote as buttons are often more convenient than web pages for controlling things, in my case the remote talks to an IR to WiFi bridge I built using the library linked. above.

  • GitHub repo arduinoWebSockets


    Project mention: Very new to Arduino, how would I get my board and a Java application to communicate? | reddit.com/r/arduino | 2021-06-02

    This is the WebSocket Arduino library. It also supports socket.io. https://github.com/Links2004/arduinoWebSockets

  • GitHub repo WS2812FX

    WS2812 FX Library for Arduino and ESP8266

    Project mention: [OC] My Aang and Zuko Painting on glass. Thinking of putting colored LED lights on the wall behind the frame, do you guys think it would be a good idea? | reddit.com/r/TheLastAirbender | 2021-02-06

    For libraries, I don't recommend the Adafruit neopixel lib. I think this is better, easier to use, more robust, and faster in ease of use and code execution. https://github.com/kitesurfer1404/WS2812FX

  • GitHub repo ESP3D

    FW for ESP8266/ESP8285/ESP32 used with 3D printer

    Project mention: Is there a market for bespoke home automation components? You may recall I built this interface to our home that speaks, rings, and lights regular alerts. It has tasmota at its heart so is hardware based and easily interfaced with Home Assistant. Is there a market for me to make this kind of thing? | reddit.com/r/homeassistant | 2021-01-22

    Great news: you can build one yourself or you can buy one! :D

    You could try things like deepC but that is again C++ https://github.com/ai-techsystems/deepC

  • GitHub repo ESP32Marauder

    A suite of WiFi/Bluetooth offensive and defensive tools for the ESP32

    Project mention: is it possible to use a one-button-bluetooth-camera-trigger with an ESP32?? | reddit.com/r/esp32 | 2021-02-06

    Maybe. Depends on whether the data between the Bluetooth pairs are encrypted. You could checkout some ESP32 Bluetooth sniffer examples, this may help you identify the camera trigger within the data stream. This may help https://github.com/justcallmekoko/ESP32Marauder let me know if you crack it :)

  • GitHub repo IoTaWatt

    IoTaWatt Open WiFi Electric Energy Monitor

    Project mention: Inverter questions | reddit.com/r/solar | 2021-04-15

    I would start by looking at what your peak power usage in terms of watts and your avg kwh used in 24 hours. This would help you in sizing. This is what I use for my power monitoring https://iotawatt.com/

  • GitHub repo WirelessPrinting

    Print wirelessly from Cura, PrusaSlicer or Slic3r to your 3D printer connected to an ESP8266 (in the future also ESP32) module

    Project mention: Prusa mini + raspberry pi zero w | reddit.com/r/prusa3d | 2021-02-22
  • GitHub repo dscKeybusInterface

    An Arduino/esp8266/esp32 library to directly interface with DSC security systems.

    Project mention: Ademco Central Office reciever manual | reddit.com/r/homesecurity | 2021-05-11

    If one doesn't like the $100 cost of Envisalink, with DSC systems there is open source software on GitHub that uses a $5 Wemos D1 mini board and another $1 worth of electronic components (couple resistors and a transistor) to interface directly to the KeyBus and then provides several methods of control.

  • GitHub repo aWOT

    Arduino web server library.

    Project mention: Vanilla Javascript OTA | reddit.com/r/esp32 | 2021-04-14

    If so, here is an example from my own web server library. I think the HTML + javascript should work with the existing backend implemented with the WebServer library that ships with the core too. I does not have a progress bar or any other nice to have features but it's as simple as it gets.
