Getting started

Necessary parts to build the project

• Microcontroller ESP32
• RXB6 433Mhz receiver

ESP-32 firmware

The whole architecture was inspired from the arduino concept with a setup() and loop() function. This is the reason why everything is broken down into separate modules below /lib. Each module has basically a setupXXX() and loopXXX() method.

Build (with PlatformIO)

$ pio run --environment esp32

# update esp
$ platformio run --target upload

Web APP

Based on state of the art technologie Vue.js + Vuetify + Webpack

Build

$ yarn --cwd app
$ yarn --cwd app build

# update esp
$ platformio run --target uploadfs

# alternative, create spiffs.bin
$ platformio run --target buildfs
