Simple Wiring and construction:

This is the easiest way to mount your brewuno, you can improve it!

Installing with Flash Download Tools (video)

Download bin files
Download Flash Download Tools
Setup like this: setup
firmware.bin offset: 0x0
spiffs.bin offset: 0x00300000
Click START button
Restart WEMOS
Connect to BrewUNO wifi (SSID: BrewUNO, Password: brew-uno).
Access AP mode ip: 192.168.4.1
Scan and configure your wifi under WiFi menu

Installing & Deployment with VS Code

Prerequisites

You will need the following before you can get started.

VS Code
PlatformIO - IDE for development with ESP8266 v2.2.2 platform installed
NPM - For building the interface (if you want)
Bash shell, or Git Bash if you are under windows

Pull the project and add it to PlatformIO as a project folder (File > Add Project Folder).

PlatformIO should download the ESP8266 platform and the project library dependencies automatically.

Once the platform and libraries are downloaded the back end should be compiling.

Edit /data/config/wifiSettings.json with yours wifi configurations.

Under PlatformIO menu: Upload File System image, and then, Upload and Monitor. You will see the ip address to access interface. AP mode ip: 192.168.4.1

Building the interface

The interface has been configured with create-react-app and react-app-rewired so the build can customized for the target device. The large artefacts are gzipped and source maps and service worker are excluded from the production build.

You will find the interface code in the ./interface directory. Change to this directory with your bash shell (or Git Bash) and use the standard commands you would with any react app built with create-react-app:

Download and install the node modules

npm install

Build the interface

npm run build

NB: The build command will also delete the previously built interface (the ./data/www directory) and replace it with the freshly built one, ready for upload to the device.

Running the interface locally

npm start

NB: To run the interface locally you will need to modify the endpoint root path and enable CORS.

The endpoint root path can be found in .env.development, defined as the environment variable 'REACT_APP_ENDPOINT_ROOT'. This needs to be the root URL of the device running the back end, for example:

REACT_APP_ENDPOINT_ROOT=http://192.168.0.6/rest/

CORS can be enabled on the back end by uncommenting the -D ENABLE_CORS build flag in platformio.ini and re-deploying.

Configuration

Standard configuration settings, such as build flags, libraries and device configuration can be found in platformio.ini. See the PlatformIO docs for full details on what you can do with this.

By default, the target device is "esp12e". This is a common ESP8266 variant with 4mb of flash though any device with at least 2mb of flash should be fine. The settings configure the interface to upload via serial by default, you can change the upload mechanism to OTA by uncommenting the relevant lines.

As well as containing the interface, the SPIFFS image (in the ./data folder) contains a JSON settings file for each of the configurable features. The config files can be found in the ./data/config directory:

File	Description
apSettings.json	Access point settings
ntpSettings.json	NTP synchronization settings
otaSettings.json	OTA Update configuration
wifiSettings.json	WiFi connection settings
