Weatherstation using MagicMirror+Rasp3b+7inch touchscreen

[jbat66]

@Saabman I know coding, but not some flavors, like java script and json, as an example or even API usage, but with Chat GPT over the last couple of months I have done a lot and learned a lot. It is great for making a function, or a small script, and then you use them as building blocks for larger projects. Shoot I have found out about services I never knew about. For example a website (openstreetmap.org) that has an API, that if you feed it GPS coordinates, it returns the street address, county, Country, etc. Another website (timezonedb.com) that if you feed it GPS coordinates it gives you the timezone, and GMT Offset.

My ChatGPT request was something like “Write a bash script that uses GPS coordinates set in variables to get the timezone” and tada I learned something.

Or using crazy sed commands (I never was good at them) to push the GPS data into the config.js for MM
#sed -i ‘/^\s*header: "TimeZone-- /c’“${THREE_TABS}”‘header: “TimeZone-- '”$TIMEZONEABB"’ --------- Altitude: ‘“$ALTITUDE_FEET”’",’ “$CONFIG_FILE”

etc.

Great build! I like it!

Thnx!

I’m still trying to figure out how to make the SmartTouch module dim the screen instead of just hiding the modules.

Just wanted to backtrack here again, if someone else is trying to do the same. I realised there was a way simpler way to achieve this: To make a script outside MagicMirror to dim the screen.

So, I had ChatGPT make me a script. The goal was to have the screen dim almost completely after 15 minutes of inactivity, and then to restore if the user touches the screen (or clicks a mouse). I then had pm2 start both scripts at boot. This however somehow prevented MagicMirror to start properly, so I ended up making a single script that started both, eg “Dim on inactivity” and “MagicMirror”.

Here are the scripts:

First making one that dims screen after a fixed period, and then restores on touch. I made a subfolder called “scripts” and named the script “dim_screen.sh”:

#!/bin/bash

# Configuration
IDLE_TIME=$((15*60*1000))  # 15 minutes in milliseconds
BRIGHTNESS_FILE="/sys/class/backlight/10-0045/brightness"
MAX_BRIGHTNESS=$(cat /sys/class/backlight/10-0045/max_brightness)
DIMMED_BRIGHTNESS=$(($MAX_BRIGHTNESS * 2 / 100))  # 2% of max brightness

# Function to set brightness
set_brightness() {
    echo $1 | sudo tee $BRIGHTNESS_FILE > /dev/null
}

# Main loop
while true; do
    idle=$(xprintidle)
    if [ $idle -ge $IDLE_TIME ]; then
        set_brightness $DIMMED_BRIGHTNESS
    else
        set_brightness $MAX_BRIGHTNESS
    fi
    sleep 1  # Check every second
done

Then I made a new script called “ecosystem.config.js” for pm2 to handle:

module.exports = {
  apps: [
    {
      name: 'MagicMirror',
      script: '/home/christian/mm.sh',
      interpreter: '/bin/bash',
    },
    {
      name: 'DimScreen',
      script: '/home/christian/scripts/dim_screen.sh',
      interpreter: '/bin/bash',
    }
  ]
};

And then cleared pm2, and re-added just the script “ecosystem.config.js”

And bingo, now the screen dims after 15 minutes of inactivity, and is restored when I touch the screen.

Hello Mr. cgillinger,

first of all thank you very much for posting.

I just got myself into RPis and would’ve loved to have a Weatherstation just like yours.
My Display is 5", 800x480. More than enough for the beginning.

Now Maybe you are able to help me out. I have a fresh install of RPi OS with NodeJS 20.11 and Magic Mirror installed.
I was able to modify some modules and change the color of the restart buttons.

However I was not able to integrate the Weather Icons or change the color of them. Also how did you manage to resize the “Forecast” module?

Any help would be appreciated.

Many greetings,
extec

I just entered the colors in the “custom.css” file, located in the MagicMirror/css folder. And if I remember correctly it was a bit sensitive to location. Let me just paste my entire custom.css, and see if that works on your PI:

}

Getting the size of the weather icons right was a lot of fiddling to find out the name of the class.

Now, I use the standard Weather module, but for my location I use swedish SMHI as provider:

{
			module: "weather",
			position: "bottom_left",
	
			//initialLoadDelay: "500",
			config: {
				weatherProvider: "smhi",
				type: "current",
				location:"Stockholm",
				lat: "XXXXXXXX",
				lon: "XXXXXXX",
				windUnits: "metric",
				degreeLabel: "true",
				howPrecipitationAmount: "true",
				showPrecipitationProbability: "true",
				colored: "True",
				
			}
		},

And for forecast I use Norweigan, Yr:

{
			module: "weather",
			position: "top_right",
			header: "Väderprognos",
			
			config: {
				weatherProvider: "yr",
				initialLoadDelay: "500",
				type: "hourly",
				location:"Stockholm",
				lat: "XXXXXXXX",
				lon: "XXXXXXXX",
				maxEntries: "9",
				fade: "false",
				fadePoint: "1",
				colored: "true",
				degreeLabel: "true",
				//showPrecipitationAmount: "true",
				//showPrecipitationProbability: "true",
			//maxNumberOfDays: "10",
		
			}
		},

Hope this helps, otherwise I’ll have to dig deeper.
