Installation and setup

1. Clone the repo from "https://github.com/Skorpinakos/IoT-2022" or export the "GitHub-Repo.zip"

2. Install node.js (https://nodejs.org/en/download/) version (18.12.1) and Python version (3.10.4)

3. To install the dependencies

   • cd into the Website directory

   • Run

     npm install
     

     (If installation hangs this is a known npm problem https://stackoverflow.com/questions/66893199/hanging-stuck-reifyprettier-timing-reifynodenode-modules-nrwl-workspace-comp we suggest re-trying a few times and giving it some time. This bug has nothing to do with our project and appears since npm version 7.0.0)

4. In a terminal

   • cd into the Edge_Compute directory

   • Start greenhouse device service (on port 3000) by running

     node controller.mjs
     

5. In another terminal

   • cd into the Website directory

   • Start the website service (on port 4000) by running

     npm run watch
     

6. Open your browser on port 4000 (http://localhost:4000/) and login with the following credentials

A basic Measurement Use Case

To initiate a simple measurement:

1. Login
2. Tap on the 'Greenhouses' option on the taskbar
3. Choose the greenhouse for which you want to start a new measurement (greenhouse ID:12 is operational)
4. Once the greenhouse page opens click on the 'New Measurement' button on the bottom right of the screen
5. A small written message will appear beside the button and notify you of the begining of the new measurement
6. When the measurement ends (after approximately half a minute depending on the processor) and its data is stored in the database a full screen popup message will notify you about the event and the page will be refreshed in order for the new data to be served to the front end.
