Hi!
I wonder, why this message (yellow text) is not cleared.

0_1488222077128_Bildschirmfoto vom 2017-02-27 19:51:24.png

I do have this for about 5 days now. Reboot will not help.

Can someone give me a hint, how to clear this?

Besides: Its pretty warm right now and no “Glätte” (ice) nor “Wind” (wind) can be expected. Its clearly an old message ;-)

Thanx!

Searching for endless hours now, but no solution in sight…

Im trying to trigger the mm-music-player module with this voicecontrol module (i say “MUSIK ON” and the mm-music-player starts a certain mp3 file). But no luck…

My microfone can record audio (tested with arecord …) …

(note: i had to change my “sudo nano /usr/share/alsa/alsa.conf” and the entries “defaults.ctl.card 1” and “defaults.pcm.card 1” from “0” to “1” to get my USB microphone working/recording)

…and my mp3 soundfile can be played (tested with “omxplayer -o hdmi …”) - and also if i click on the mm-music-player-module…

pm2 logs mm (after a reboot) shows this:

I…

installed the voicecontrol and mm-music-player
double checked the code
changed the mp3 file with another
implemented the code like “GinSeng” stated some lines above.
created the hotwords over at snowboy and copied them to “/MagicMirror”, “voicecontrol” and “mm-music-player” directories
…
But im not able to find the problem…

Any suggestions?

Thanks a lot for your help…

What i also did, was a complete reinstall of the PIR-Sensor

I followed the steps, “Banglee” described some lines above:

ok so lets go step by step:
cd ~/MagicMirror/modules/

now we will remove the PIR folder:
rm -rf MMM-PIR-Sensor

and from here, we’re going to reinstall the MMM-PIR-Sensor modul:

git clone https://github.com/paviro/MMM-PIR-Sensor.git
cd MMM-PIR-Sensor

run the following cmd here:
npm install and wait, this can take a few minutes.

Now you’ll have to add pi to gpio
sudo useradd -g pi gpio

and reboot your Raspi:
sudo reboot

Sorry, no further ideas so far (maybe you can open a PIR-Sensor troubleshooting thread)?

First things that come to my mind:

maybe a “sudo” is missing? Like sudo npm install --unsafe-perm?
are you executing this from the MMM-PIR-Sensor directory ?

Also had the “white screen” problem. I installed a complete new Raspian (with PIXEL), a new MagicMirror - including node.js in version 7.3.0
As soon as i tried to get the MMM-Pir-Sensor working, it failed (with an white screen). Heres, how i solved my problem.

At first: Theres no need to downgrade the node (i tried this too, and had no luck)

I figured out, that my problem was an MMM-PIR-Sensor installation error i did not recognized at the beginning. When i tried “npm install” i got something like this (an error):

"gyp WARN EACCES user “root” does not have permission to access the dev dir “/root/.node-gyp/5.12.0”

I figured out, that there are two ways of solving this:

CHOWN the directory the install procedure tries to install
use “npm install --unsafe-perm”

Im aware that option two is not the “elegant” way, but it solved my problem (and i did not have to change directory permissions).

I removed all files and git the files again (like described some lines above from banglee) and then just use “npm install --unsafe-perm”

The “–unsafe-perm” option was the key to my problem…

Same problem here. My newsfeed works for some time (can not say how long) and then stops receiving new news…

@lolobyte

Try to look at the original files which came in the downloaded package. I also had problems and realized later, that i had forgotten some characters…

In your case, i think you have to put each title and url in parentheses. Look at my example from above and also dont miss commas…

Something like this:

                               {
                                title: "Süddeutsche Zeitung",
                                url: "http://rss.sueddeutsche.de/rss/Topthemen",
                                },
                                title: "Tagesschau",
                                url: "http://www.tagesschau.de/xml/rss2",
                                "http://www.stimme.de/storage/rss/rss/regioticker/regioticker.xml",
                                 }

As i mentioned above - take the original files as reference, go throug it character by character and you will get it some trys later…

I build a bathroom mirror and its doing well (but installed it just a few days before). See my thread: link
I read a lot about humidity and elektronics, but could not get a valid result if a monitor would get damaged or not.

I think it also depends a bit in how your bathroom is constructed and how humidity is handled. My bathroom is based on chalk walls which absorb nearly 85% of the fog i produce when i shower.

The monitor i used for my mirror, has also no air holes at the back. I think this will also prevent some damage…

Managed to get it working again. Cant say, what went wrong before. Thread can be closed…

@Knox
