WateringOfThings

Repository for the web application course.

React Native Application

Requirements

• Installed React Native: https://facebook.github.io/react-native/docs/getting-started.html

Installation

1. Install dependencies:

   cd ReactNativeApp
   npm install
   react-native link

2. Configure the host of your REST API under app\network\host.{platform}.js

Troubleshooting

• App quits after start or when selecting a plant image:

  • Check whether manual configuration of the image-cropper is correct: https://github.com/ivpusic/react-native-image-crop-picker#post-install-steps

• App quits when selection a plant image:

  • Check whether the permissions to the Photo Library are configured in your XCode-Project

Server

Requirements

• Python 3
• Sqlite
• Running Redis server

Installation

1. Create a virtualenv to isolate our package dependencies locally

   cd server
   virtualenv env

2. Start virtual environment

   source env/bin/activate  # On Windows use `env\Scripts\activate`

3. Install dependencies

   pip install -r requirements.txt

4. Init database

   python manage.py makemigrations api
   python manage.py migrate api

5. Adjust the config files for your setup

   • MQTT-Broker: watering_of_things/config/mqtt_settings.py
   • Redis-Server watering_of_things/celery.py Here you can find a list of public mqtt brokers: https://github.com/mqtt/mqtt.github.io/wiki/public_brokers

6. Start server

   python manage.py runserver

7. Start Celery beat and worker (for regular moisture measurements)

   celery -B  -A watering_of_things worker -l info

8. Add a valid controller id, e.g.

   python manage.py shell # Switch to the python shell
   from watering_of_things.api.models import MicroController
   MicroController(’<your valid id>’).save()
   exit()

Hardware

Requirements

• Hardware setup similar to this: https://github.com/wochinge/WateringOfThings/blob/master/Technical%20Documentation/Pictures/platinenlayout.png
• Arduino IDE: http://www.arduino.org/downloads
• Set up your board in the IDE (we used a NodeMcu v.1.0)

Installation

1. Create a file called WifiConfig.h (see WifiConfig_example.h for an example) which stores the credentials for your wifi
2. Create a filed called MqttConfig.h (see MqttConfig_example.h for an example) which stores the credentials for your mqtt broker
3. Create a filed called ID.h (see ID_example.h for an example) which stores the unique ID of the hardware controller. Note: This unique ID should also be stored on the server as valid controller id
4. Install the following libraries through the Arduino IDE:
   • PubSubClient (Nick O’Leary)
   • ArduinoJson (Benoit Blanchon)
5. You might change the pin settings to fit your hardware
6. Compile it and load it on your hardware
