\n\n---\n\nESP32-based Home Energy Monitor: monitors electricity consumption of your entire house with a single CT sensor.\n\n## Structure\n\nThis project consists out of multiple components:\n\n| Folder | Description | Build status | \n| ----------------- | ------------------- | ------------ | \n| `src-app` | Mobile app (Ionic) | n/a |\n| `src-aws` | Serverless AWS backend + GraphQL API | ![AWS Build Status](https://github.com/Savjee/home-energy-monitor/workflows/aws/badge.svg) |\n| `src-esp32` | Firmware for the ESP32 (measuring device) | ![Firmware Build Status](https://github.com/Savjee/home-energy-monitor/workflows/firmware/badge.svg) |\n\n(TODO: add instructions on how to deploy all of this. 😅)\n\n## Video explanation\n\n

\n\nRead my blog post for more instructions: [https://savjee.be/2019/07/Home-Energy-Monitor-ESP32-CT-Sensor-Emonlib/](https://savjee.be/2019/07/Home-Energy-Monitor-ESP32-CT-Sensor-Emonlib/)\n\n## Cloud Architecture\n\nThis is the cloud architecture that powers the energy meter and the app:\n\n![AWS Cloud Architecture](https://savjee.github.io/home-energy-monitor/readme-images/architecture.png)\n\nIn a nutshell:\n* The ESP32 has a MQTT connection with AWS IoT Core\n* Every 30 seconds, 30 measurements are sent to AWS\n* These measurements are stored in DynamoDB (IoT Rule)\n* Once a day, all readings from the previous day are archived to S3\n* A GraphQL API (hosted on Lambda) exposes the data stored in DynamoDB\n\n## Screenshots\n\nWeb dashboard, built on top of the GraphQL API:\n\n![Screenshot Web Dashboard](https://savjee.github.io/home-energy-monitor/readme-images/web-dashboard.png)\n\nWhat is displayed on the ESP32 OLED display:\n\n![Screenshot ESP32 OLED](https://savjee.github.io/home-energy-monitor/readme-images/esp32-oled.jpg)\n\n\n## DIY Requirements\n\nTo build your own Energy Monitor you need the following hardware:\n\n* ESP32\n* CT sensor: YHDC SCT-013-030 (30A/1V)\n* 10µF capacitor\n* 2 resistors (between 10k-470kΩ)\n\nOther requirements:\n* AWS Account (Should be able to run in free-tier)\n* Install [PlatformIO](https://platformio.org) on your system\n* Drivers for your ESP32 board\n\nRead my blog post for more instructions: [https://savjee.be/2019/07/Home-Energy-Monitor-ESP32-CT-Sensor-Emonlib/](https://savjee.be/2019/07/Home-Energy-Monitor-ESP32-CT-Sensor-Emonlib/)\n\n\n## Contribute\n\nI'm happy to merge in any pull requests.

The header file eliminates the labor of\nfinding and changing all the copies as well as the risk that a failure to\nfind one copy will result in inconsistencies within a program.\n\nIn C, the usual convention is to give header files names that end with `.h'.\nIt is most portable to use only letters, digits, dashes, and underscores in\nheader file names, and at most one dot.\n\nRead more about using header files in official GCC documentation:\n\n* Include Syntax\n* Include Operation\n* Once-Only Headers\n* Computed Includes\n\nhttps://gcc.gnu.org/onlinedocs/cpp/Header-Files.html\n" }, { "path": "src-esp32/lib/README", "content": "\nThis directory is intended for project specific (private) libraries.\nPlatformIO will compile them to static libraries and link into executable file.\n\nThe source code of each library should be placed in a an own separate directory\n(\"lib/your_library_name/[here are source files]\").\n\nFor example, see a structure of the following two libraries `Foo` and `Bar`:\n\n|--lib\n| |\n| |--Bar\n| | |--docs\n| | |--examples\n| | |--src\n| | |- Bar.c\n| | |- Bar.h\n| | |- library.json (optional, custom build options, etc) https://docs.platformio.org/page/librarymanager/config.html\n| |\n| |--Foo\n| | |- Foo.c\n| | |- Foo.h\n| |\n| |- README --> THIS FILE\n|\n|- platformio.ini\n|--src\n |- main.c\n\nand a contents of `src/main.c`:\n```\n#include \n#include \n\nint main (void)\n{\n ...\n}\n\n```\n\nPlatformIO Library Dependency Finder will find automatically dependent\nlibraries scanning project source files.\n\nMore information about PlatformIO Library Dependency Finder\n- https://docs.platformio.org/page/librarymanager/ldf.html\n" }, { "path": "src-esp32/platformio.ini", "content": "; PlatformIO Project Configuration File\n;\n; Build options: build flags, source filter\n; Upload options: custom upload port, speed and extra flags\n; Library options: dependencies, extra library storages\n; Advanced options: extra scripting\n;\n; Please visit documentation for the other options and examples\n; https://docs.platformio.org/page/projectconf.html\n\n[env:esp32doit-devkit-v1]\nplatform = espressif32\nboard = lolin32\nframework = arduino\nmonitor_speed = 115200\n\nbuild_flags =\n -DCOMPONENT_EMBED_TXTFILES=certificates/certificate.pem.crt:certificates/private.pem.key:certificates/amazonrootca1.pem\n -DCORE_DEBUG_LEVEL=0\n\nlib_deps =\n https://github.com/Savjee/EmonLib-esp32.git\n Adafruit GFX Library\n Adafruit SSD1306\n adafruit/Adafruit BusIO @ ^1.7.2\n MQTT\n NTPClient\n" }, { "path": "src-esp32/src/config/config.dist.h", "content": "#ifndef CONFIG\n#define CONFIG\n\n/**\n * Set this to false to disable Serial logging\n */\n#define DEBUG true\n\n/**\n * The name of this device (as defined in the AWS IOT console).\n * Also used to set the hostname on the network\n */\n#define DEVICE_NAME \"*****YOUR AWS IOT DEVICE NAME******\"\n\n/**\n * ADC input pin that is used to read out the CT sensor\n */\n#define ADC_INPUT 36\n\n/**\n * The voltage of your home, used to calculate the wattage.\n * Try setting this as accurately as possible.\n */\n#define HOME_VOLTAGE 245.0\n\n/**\n * WiFi credentials\n */\n#define WIFI_NETWORK \"****** YOUR WIFI NETWORK NAME *******\"\n#define WIFI_PASSWORD \"****** YOUR WIFI PASSWORD *******\"\n\n/**\n * Timeout for the WiFi connection.
