Visualizing METAR data on a Raspberry Pi with LEDs.
Project description
# About
Inspired by some DIY projects, this script allows you to quickly discern weather conditions by
changing the colors of LEDs to reflect the current METAR information. You will need a Raspberry
Pi, some WS281X LEDs, and the four letter designators of the airports you are interested in.
This code assumes you've connected to GPIO 18 (PWM0) and have added `blacklist snd_bcm2835` to the
`/etc/modprobe.d/snd-blacklist.conf` file.
# Install
```
sudo su
apt install python3-venv
python3 -m venv /opt/rpi_metar
source /opt/rpi_metar/bin/activate
pip install rpi_metar
```
# Configuration
You need to tell `rpi_metar` which LEDs correspond to which airports. You may do this by
creating the `/etc/rpi_metar.conf` file. There must be an `[airports]` section where the airport
codes are assigned to LEDs. For example:
```
[airports]
KDEN = 0
KBOS = 1
```
The LED indexes can be skipped and do not need to be continuous. If you don't have an LED
associated with an airport, it does not need to be entered.
# Autostart
Create the `/etc/systemd/system/rpi_metar.service` file with the following contents:
```
[Unit]
Description=METAR Display
[Service]
ExecStart=/opt/rpi_metar/bin/rpi_metar
User=root
Group=root
Restart=always
[Install]
WantedBy=multi-user.target
```
Make systemd aware of the changes:
```
systemctl daemon-reload
```
Make sure it's set to run at boot:
```
systemctl enable rpi_metar
```
Start the service:
```
systemctl start rpi_metar
```
