A simple CLI app I made because I wanted to use data from Yr.no (which basically uses frost.met.no) and get it into Home Assistant.

Then I got sidetracked and made a CLI tool that can be used to get weather data because I found the idea of using React in terminal to be kinda fun.

Description

Kommuner (Municipalities)

First one should go to Kommuner and select the municipality you want to get data for.

The app will then fetch the data from frost.met.no and create a database containing the measuring stations for those municipalities.

Målestasjoner (Measurement stations)

This enables the selection of a specific measurement station. Some are updated at a too slow of interval to be useful, so you can select the ones you want to use.

Temperatur (Temperature)

After selecting a municipality and a measurement station, you can retrieve the temperature data for those stations.

How to run

Install bun if you don't have it already: bun.sh

To install dependencies:

bun install

To add secrets go to frost.met.no and get your secrets.

Put them in a .env file in the root of the project:

CLIENT_ID=your_client_id
CLIENT_SECRET=your_client_secret

To run:

bun start

Home Assistant (MQTT)

Favorited stations will be published to Home Assistant via MQTT and automatically discovered if the extension is running and the secrets are set.

The following needs to be added to the .env file in the root of the project:

MQTT_USER=username_in_homeassistant
MQTT_PASS=password_to_said_user

This enables adding all the favorited sensors as a single card:

Dev notes

Use bun dev to start with the possibility to inspect the code (Tried to get react-devtools working, but it seems broken after React 19 update)

Use bun test to run some tests, they just create the databases and checks that initializing work. Tests will be added if they make the development easier, as HMR does not work yet.

This is work in progress and just for fun, so dont rely on it for anything important!
