<?php

return [
    'apiKey' => 'Open Weather Map API Key',
    'units' => 'metric', // *OWM
    'lang' => 'pl', // *OWM
    'cacheDuration' => 600, // Yii cache duration
    'latitude' => 0.000, // Your location latitude
    'longitude' => 0.000, // Your location longitude
];

*OWM = See https://openweathermap.org/api/one-call-api for options

Docker Env

docker-compose is located in ./docker folder.

Raspbian:

/boot/config.txt

Disable camera LED:

disable_camera_led=1

Rotate HDMI display 90 degrees:

Run Chromium in kiosk mode with Open Weather Map interface:

@chromium-browser -kiosk -noerrdialogs --disable-session-crashed-bubble http://localhost:8000

Hide cursor:

@unclutter -idle 0

Requires unclutter to be installed (sudo apt-get install unclutter).
