Top 23 Esp32 Open-Source Projects

Tasmota
Alternative firmware for ESP8266 and ESP32 based devices with easy configuration using webUI, OTA updates, automation using timers or rules, expandability and entirely local control over MQTT, HTTP, Serial or KNX. Full documentation at
Project mention: Printing emails based on Message Filters, does not seem possible | /r/Thunderbird | 2023-12-02All of my office devices are connected to Sonoff S31 smart plugs, flashed with Tasmota on their own locked-down VLAN, and can be controlled via voice, Alexa, Tasker automation on my Android, NFC tags at my office door and various scripts triggered via my StreamDeck (on Linux). This all works fantastic, and I can turn on or off my devices, including my printer, when I start or end my day at work.

Marlin
Marlin is an optimized firmware for RepRap 3D printers based on the Arduino platform. Many commercial 3D printers come with Marlin installed. Check with your vendor if you need source code for your specific machine.
Project mention: Why Prusa is floundering, and how you can avoid their fate | news.ycombinator.com | 2023-12-26There is _a lot_ wrong with Marlin. It is a complex codebase, full with ancient artefacts, litterred with preprocessor ifdefs every 2-3 lines of code, dynamic includes in the middle of CPP files, etc[1]. It's about as unreadable as C++ code gets--well, I guess it's not template metaprogramming.
Klipper by contrast is a breeze to read through[2].
I am very grateful for Marlin, for all of reprap, and everyone who has contributed to it. But saying there is nothing wrong with it is straight up misguided.

Project mention: Any good/worthwhile Camera sensor modules for arduino/pico for still photography? | /r/diyelectronics | 2023-12-11
You could just buy ready-made ESP32 boards with an OV2640 camera built-in, then customize the example sketch from https://github.com/espressif/arduino-esp32/tree/master/libraries/ESP32/examples/Camera/CameraWebServer to your liking.

Hardware programming used to require you to learn C/C++. If you’re already familiar with JavaScript or TypeScript, you will be delighted to learn about DeviceScript, a TypeScript programming environment for microcontrollers. In this blogpost you’ll learn the basics of electronics and DeviceScript. We will create the “hello world” of programming: making an LED blink!

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: I built an offline smart home, and why you should too | news.ycombinator.com | 2024-01-11I am planning to do this soon(TM).
Probably starting with ESPHome to control my heat pumps over IR.
The remote works but I forget to turn it off when not in one of the rooms, and it can't do smarts like keeping temperatures in desired bounds.
An ESP32 running ESPHome with high power IR LED, a presence sensor, temperature sensor, and some pre-built library to control heat pumps[1]. it looks like it should be fairly simple to implement with Home assistant.
Now if I could only disable the beep from the heat pumps receiving commands.
I would like to do smarter lighting, but the lack of decent smart light switches that support local control and are also licenced for use in AU are a blocker there.

Project mention: Show HN: Extend Zigbee sensor range with LoRaWAN | news.ycombinator.com | 2024-03-18
This is a fantastic idea, thanks for sharing. I feel like LoRaWAN and LoRAMESH are the perfect solution for shuffling messaging around for home and property sensors, easily traversing a couple miles in poor conditions.
Prior to seeing this I was thinking about how to use the Meshtastic [0] project to fundamentally provide simple UDP services for message brokering over LoRa. There are so many sensors that could easily hook or connect to devices acting as network routers that could bridge other protocols across long distances very easily.
Have you looked at doing something similar with ZWave at all?

willow
Open source, local, and self-hosted Amazon Echo/Google Home competitive Voice Assistant alternative
> - People might criticize my messy/bad/unfinished code
As someone who has created and maintained open source projects (most recently Willow[0]) for two decades I get a kick out of this.
Of course when interacting with users and feedback I keep it polite but in my head I'm thinking "You like to talk. I actually DID this. Shut up or submit a PR".
Surprise surprise they almost never do.

Project mention: ESP32-BLE-Keyboard Example - "does not name a type" error | /r/arduino | 2023-10-24
I am trying to get started with the bluetooth keyboard example for ESP32. using the example, it throws the error: "Compilation error: 'BleKeyboard' does not name a type" I have tried to compile this in Arduino 1.8 and 2.2.1 and on multiple computers. all fail to compile. I even tried to downgrade the ESP32 package to 2.x to no avail. What am i missing here?
