PixelWeather is a weather station network that collects environment data using "nodes" (a collection of microcontrollers and sensors). This repository contains the implementation of the PixelWeather Messaging Protocol (PWMP), which is used to exchange information between nodes and a server application. You will also find both the server software as well as the client library.
PWMP allows nodes to communicate with the database in a fast and type-safe way. It uses messages to exchange information. The server is responsible for handling these messages and communicating with the database. The client library is used to create and send messages to the server.
A more in-depth description of the protocol can be found here.
READMEs can be found in each crate separately.
The PWMP server uses a PostgreSQL database. It's recommended to use the latest version (16.x+). You must prepare your database by running the create_schema.sql script.
The examples use a dummy MAC address which you'll need to add to the database to run them:
INSERT INTO devices("id", "mac_address", "note")
VALUES ('1', '01:02:03:04:05:06', 'testing device');
INSERT INTO settings("node")
VALUES (1);The current version of the server does not enforce security measures beyond checking if the node is authorized to communicate with the server.
It should be noted that no sensitive data is exchanged between the server and the nodes. The server does not store any sensitive data.
Since PWOS only supports encrypted WiFi networks, all communication is encrypted to anyone outside the network.
