Overview

This repo is build for a weatherstation powered by a WEMOS D1 Mini or ESP32. For web- and database server we use a Raspberry Pi. Here you can get 3D-Models of Serverracks for this.

Version logs

Version	Description	Date
1.0	basic functionality (webserver with charts and database connectivity); Arduino / ESP8266 tesscript	2024.11.07
2.0	completely reworked ui/ux, databasefunctions and backend	2025.06.23

Getting started

Install Nginx

sudo apt update sudo apt install nginx start nginx server sudo systemctl start nginx autostart nginx server on boot sudo systemctl enable nginx check status sudo systemctl status nginx

Output shall be: ● nginx.service - A high performance web server and a reverse proxy server Loaded: loaded (/lib/systemd/system/nginx.service; enabled) Active: active (running)

To restart nginx: sudo systemctl restart nginx

Test configurationfile sudo nginx -t

if the firewall hit problems sudo ufw allow 2292

Setup Nginx Server

Nginx configuration File (nginx.conf)

user www-data;
worker_processes auto;
pid /run/nginx.pid;
error_log /var/log/nginx/error.log;
include /etc/nginx/modules-enabled/*.conf;

events {
    worker_connections 768;
    # multi_accept on;
}

http {
    include mime.types;

    server {
        listen 2292; #define port of webserver
        root /var/www/html/dist/web/browser;

        # Optionally, define an index file (like index.html)
        index index.html;

        # Add additional configuration, like handling 404 errors if necessary
        location / {
            try_files $uri $uri/ /index.html;
        }
    }
}

copy angular build file to nginx location cp -r [path_to_dist_folder] var/www/html/

Install all needed librarys for the database sudo npm install sqlite3 cors express

test database node path/to/your/database/folder/database.js

Setup automatic start of the DB server after boot

build a file for the database service sudo nano /etc/systemd/system/dbserver.service

write your paths and user into the file
