How I got my Magic Mirror working on a Raspberry Pi 0 (zero)

delusional112

Hi guys,

Used the image from @SebTota. MM2 is starting and running. But i can’t get my pi zero W to connect to my wifi. I edited the WPA_supplicant file. Can’t get it to work. Also i tried with a command found on google to scan for networks. But it responds Wlan0 can’t scan.

Thanks in advance for the help.

I didn’t use the image but used my own installation. Therefore In can’t tell for sure. However,where ist the wpa_supplicant.conf you are referring to located? Did you use/create one directly on /boot? This should automatically be copied to the “normal” location and then automatically get deleted.

My wpa_suplicant.conf file looked like

ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=1
network={
ssid="NAMEOFNETWORK"
psk="WPA2KEY"
}

(of course you have put your network name and key in, but keep the quotation marks).
Which editor did you use (not that there is a problem with the line end or something similar)?

Once it worked, I replaced the clear text psk by a passphrase by using wpa_passphrase.

Man I put the mirror in the closet for a little, came back to finally finish the frame and put it on the wall, updated it and more trouble. Oh gosh.

@Mitchfarino Thanks for sharing my link!

Did anyone get this working on the Pi Zero or Pi Zero W after the new update?

@SebTota
Which updates are you referring to? I’m still using Raspbian Jessie Light (I didn’t use the image provided in this thread but my own installation and didn’t update so Stretch yet), which is up to date (according to sudo apt-get update && sudo apt-get upgrade) and the latest version of MagicMirror (according to cd ~/MagicMirror && sudo git pull) and don’t see any (new) issues on my Pi Zero W.

What are your problems?

@Hawking I get an error saying that modules/color is missing or something like that. I’ve been working on it for 3 days but can’t get it to work.

@SebTota

Do you also get this error if you use a very minimal config file like

var config = {
        port: 8080,
        ipWhitelist: ["127.0.0.1", "::ffff:127.0.0.1", "::1"],
        language: "en",
        timeFormat: 24,
        units: "metric",
        modules: [
                {
                        module: "clock",
                        position: "top_left"
                },
        ]
};

/*************** DO NOT EDIT THE LINE BELOW ***************/
if (typeof module !== "undefined") {module.exports = config;}

If this works, you can step by step add the modules you want and see which one causes the problem.

The exact error message would be helpful for an analysis.

@SebTota I went to my old image from before the update and thats still working fine, but when I updated it, it again had the error come up. The only difference is last time I did the update it said Error: Cannot find module ‘colors’
