given that we will have a regular update quarterly, and we have such a large number of new users experiencing troubles after updates (mostly cause they have a ton to learn)… I have developed a script I would like to get included for future updates…

it should handle all the work…
and give you a trial run of all that…

only applying changes if u request them

give it a try
this works on Mac as well

  bash -c  "$(curl -sL https://raw.githubusercontent.com/sdetweil/MagicMirror_scripts/master/upgrade-script.sh)"

no changes are made to the local repo or the working copy

if you WANT to actually apply the changes do

  bash -c  "$(curl -sL https://raw.githubusercontent.com/sdetweil/MagicMirror_scripts/master/upgrade-script.sh)" apply

there is a log file in the installers folder…

@lusiess01 ok, we have seen this only a few times… but in each case it was a problem with the memory card. stuff written doesn’t stick…

I also have a newer installer that resolves a lot of problems with PM2, and supports installing on non-PI systems (Mac, pi zero, odroid, jetson nano)

 bash -c  "$(curl -sL https://raw.githubusercontent.com/sdetweil/MagicMirror_scripts/master/raspberry.sh)"

i run MM on an ODroid Xu4… I think C2 would be ok.
le Potato has an ubuntu image 18.04 at least…

so its seems reasonable… some supporting modules (speech reco mostly) might be lagging

@dazza120 no. Motion is not related to MM. It can do all sorts of things. Record video, take snapshots, and a lot more. Supports just about every camera.

And has exits which can be used to inform others of motion, video files, …

So, follow it’s install instructions. Then edit /etc/motion/motion.conf, and update the lines I documented in the readme. This will call the script I provided to inform my module of motion(start and end)

U also customize the motion app on sensitivity, delay, etc etc. All things I have seen people ask about.

@mykle1 sorry, you are using some words that don’t describe well what the problem is…

i THINK you said

when I try to load image files (local to the MM system), I use a URL string. 
that URL string is 'relative' to the base of my server, defined by '??????' (you didn't supply that)

when a URL fails to load, I get error 404. (not found). 

but how do I handle this?

you would add an onerror() handler for the img object
this will get called ONLY when there is an error

img.onerror = funtion(event_object){
var img_with_error = event_object.currentTarget
img_with_error.src=??? the url of the failing image
}

see https://www.w3schools.com/jsref/obj_event.asp
for more info in decoding the event object

here are some pics of the two charts

two charts upper right

two charts closer view

one chart

@mykle1 I am also using your MMM-BMW-DS module

Erase both lock files, and go again

@mykle1 note that your onerror handler could get stuck in a loop IF the forced replacement url also fails

@lavolp3 yeh, one of the TV show scrapers failed too for similar cause.

@KSumwalt it seems that python has added type checking, which it wasn’t using before.

there was another python related type checking problem a few days ago…

looks like the node_helper has launched the python script to compare the face files, and run into a problem checking the parms passed to it.

@lavolp3 where did the pr come from? what repo? git clone that repo to install and test

@Bugsounet he said “because of other issues.”

@Cr4z33 no… idea… I would reinstall MM (use my script), just rename the old MM folder to something else,
then install my module version to verify

then u can start looking around… i installed from scratch like that to test before I sent to you, and others have confirmed it works for them too.

@Michael-Schw if you don’t use pm2 you should, it will start at boot… if you didn’t install it with my scripted install, then use the fixuppm2.sh script from here
https://github.com/sdetweil/MagicMirror_scripts

just cut/paste that one line to run that script.

shutdown and reboot are commands built in to linux

sudo shutdown now (-r | -h, -r means reboot, -h means halt)
sudo reboot , is the same as sudo shutdown -r

turn off the pi screen saver, also see my screensaveroff script…
(again if you had run my script as part of install, it would have prompted and done all this for you.
my script is listed in the alternative install section of the MM doc)…

none of my tvs support cec, so I created my own module for sleep (using a webcam for wakeup), it just hides all the modules,
alexaControl supports that too (vgencmd:‘hide’)
MMM-SleepWake

my pis & tvs run 24x7

from the README.md

### Control devices
These are configured devices you can use. If you want to change their name you must edit the translation file inside `/translations/en.json`. You can also add languages. 

| Option            | Description
| ----------------- | -----------
| `refresh`         | This refreshs your Mirror. <br /> ***Default value:*** `true` <br /> ***Possible value:*** `true` and `false`
| `restart`         | This restarts your Mirror with PM2. So make sure the `pm2ProcessName` is right. <br /> ***Default value:*** `true` <br /> ***Possible values:*** `true` and `false`
| `stop`            | This stops your Mirror with PM2. So make sure the `pm2ProcessName` is right. <br /> ***Default value:*** `true` <br /> ***Possible values:*** `true` and `false`
| `reboot`          | This reboots your Pi. <br /> ***Default value:*** `false` <br /> ***Possible values:*** `true` and `false`
| `shutdown`        | This shutdowns your Pi. ***Note:*** When you shutdown the Pi your devices aren't available. So you must start your Pi manually. <br /> ***Default value:*** `false` <br /> ***Possible values:*** `true` and `false`
| `monitorToggle`   | This can switch your monitor on and off. Make sure the used command work for you. Look at the option `vcgencmd` <br /> ***Default value:*** `true` <br /> ***Possible values:*** `true` and `false`

devices not found

1. Devices not found: <br />
    * Make sure that your Alexa and Pi are in the same Wifi. I had also the problem that my Pi was in the 2.4GHz Wifi and my Alexa in the 5GHz Wifi. It's only a problem when you discover the devices. To solve the problem disable one of the Wifis for a moment or turn the Wifi on your Pi on and off till it works.

    * Have you used the port before? Try every devices from the mirror. Probably the name is wrong. If that happen delete the device and discover for new devices. Define yourself ports for notification and custom devices to prevent this problem.

NOT in the readme

the startPort MUST BE different for each MagicMirror device

the discovery records the ip address and port for each device, when an action is required, alexa send a web request to that ip and port. (which the module handles)

@Bugsounet open a PR, describe the problem, and your solution

@Michael-Schw said in MMM-AlexaControl or MMM-AlexaOn/Off setup:

restart Spiegel pm2
spiegel refresh
Spiegel Monitor
stop Spiegel pm2

these names are device names.

remember these are plugs, so the command is alex turn on (device name) , or alexa turn off (device name)

there is a file in the translations directory for changing the device names… and language

mine looks like

{
    "PAGE": "page ",
    "REFRESH": "refresh mirror",
    "RESTART": "restart mirror",
    "STOP": "stop mirror",
    "REBOOT": "reboot mirror",
    "SHUTDOWN": "shutdown mirror",
    "MONITOR": "mirror"
}

my extension to this was to put the name between any 2 words
reboot mirror = reboot [name] mirror

my mirrors are named,
office, hall, desk, desktop, catalina, nano

I changed Monitor to Mirror
(and also provided deviceName:??? in config)

so I can say

alexa turn off hall mirror

U would say (unless u change the translations file, and redo disocvery, I think u have to delete the devices to get new name used)
alexa turn off spiegel monitor

alexa turn on spiegel refresh

some of the verbiage is hard, but best u can do with on/off switches
