Do you have an idea how to solve it?

//edit: Just removed the MMM-PIR-Sensor directory, cloned it again from GitHub and made a fresh installation worked. Seems like I messed up the node_modules folder.

@chrizzz said in MagicMirror² v2.15.0 is available don't work.:

I do have some strange things after the update.

At first, the new weather module is just “loading” without displaying content. Even after 30+ minutes. Is there something wrong with the config? I saw that there is a minor issue with the data request which will cause it to load for ~10min (or to reduce the update interval).

{
			module: "weather",
			position: "top_right",
			classes: "always",
			config: {
				// See 'Configuration options' for more information.
				type: "current",
				locationID: "YYY",
				appid: "XXX"
			}
		},

I checked this again with switching back to the old module and the old module works. The forcasting takes 10min (as expected) but the module itself works. I thought this might be something with the connection to the API. Any ideas?

@sdetweil yes I did and both worked.

I did npm install in all module folders too and did the npm install of MM multiple times just to check if something is wrong

And I have new lines of errors in the log, I don’t understand why these syntax errors appear. I checked my config file and everything looks fine. Regarding git, does this mean it couldn’t connect to github?

It works again. I think it was my mistake in the config based on the classes setting or compared with the carousel module.

@sdetweil

git version 2.20.1

@sdetweil but I have modules with available updates and the update notification module doesn’t work for a few months. I did my last MM update without been notified. I did it just because it was weird to have such a long time without the update notification

@sdetweil sorry Sam, I think I don’t get your answer.

Hey guys,

I am struggling with the default module “updatenotification”. It doesn’t show the notification bar if there is an update for MM or one of the modules.

The mm-out.log shows:

[08.02.2021 18:55.19.771] [LOG]   Initializing new module helper ...
[08.02.2021 18:55.19.773] [LOG]   Module helper loaded: updatenotification
[08.02.2021 18:55.24.000] [LOG]   Connecting socket for: updatenotification

There aren’t any log entries in mm-error.log

My config has these lines for the module:

{
			module: "updatenotification",
			position: "top_bar",
			classes: "always"
},

I tried it without the classes line too.

My MM version is 2.14.0

//e: I used the “Troubleshooting” space and not the one in modules because I thought default modules would fit to this space better.

@evroom said in new update/upgrade script, ready for testing:

@ChrizZz said in new update/upgrade script, ready for testing:

Now my Pi is downloading the electron v3.1.13 version with 3.01 kB/s.

It looks like github has problems. I also cannot download other stuff from it with proper speed or without running into a timeout. Perhaps local or depends on your ISP region.

I started installing electron in a new terminal session and it is downloading now with 16 kB/s. Maybe a stupid decission, maybe not.

Current status: 45% downloaded in the new terminal session, 18.5% downloaded as part of the MM update.

//edit: I stopped the inital installation, downloaded the right electron file from a mirror and placed the zip file in the /home/pi/.cache/electron folder. After that I updated electron manually. It worked well and after that I started npm install of the new MM version again. Now everything is updated without waiting years to download the zip from Github.

@sdetweil said in new update/upgrade script, ready for testing:

@surger13 ok, looks like we have to fight the manual way

do

cd ~/MagicMirror
git stash
git merge
npm install

took the manual way too because of the same probs. Now my Pi is downloading the electron v3.1.13 version with 3.01 kB/s. can I stop the installation process to update electron manually?

sorry to use the same topic. I have also trouble with the update to 2.10.0. The update script works, but I still have the notification that there is an update for MM. But the update log ends with “Upgrade ended - Do Jan 2 20:24:45 CET 2020”.

I have a new strange error and I think it’s just if I restart mm with “pm2 restart mm”. If I reboot my pi, everything is fine.

Is it possible to add more than 1 event and the module switches between the events with fade in and fade out?

@dragontattoo said in MMM-Face-Reco-DNN - All new Face Recognition:

Is it working fine??

Depends on how you define working fine…The face recognition is working quite good, setting it up is easy with the advice you get in this thread. For me it’s just the “slow” reaction to activate the display which is an issue. But I’m optimistic that there is a way to solve it and I have a special environment with a display which hasn’t CEC control.

Sound a little bit long to me, for me it works faster. But it took a while until they are startet. Do you use default settings?

is it common that it takes 40sec between face recognition and turning the TV on?

I see it happen after a freshly restarted pi, that it takes 40/45sec. The scenario is that I restart my pi, mm is autostarting and the TV is turned off by the module. Between the restart and the 1st face recognition is ~3min time.

@ChrizZz
Yes you need to use one of the Face Reco Module that this works. Better my new Module ;) it’s much more accurate.

Thanks, I will use your new module.

During the setup I have another issue. It’s when I want to start encoding I get this error message:

Traceback (most recent call last):
  File "encode.py", line 5, in <module>
    from imutils import paths
  File "/usr/local/lib/python3.7/dist-packages/imutils/__init__.py", line 8, in <module>
    from .convenience import translate
  File "/usr/local/lib/python3.7/dist-packages/imutils/convenience.py", line 6, in <module>
    import cv2
ModuleNotFoundError: No module named 'cv2'

I think it’s a problem of my OpenCV installation where I skipped the virtualenvs. In step 6 of the tutorial I should do this:

$ cd ~/.virtualenvs/cv/lib/python3.5/site-packages/
$ ln -s /usr/local/python/cv2/python-3.5/cv2.cpython-35m-arm-linux-gnueabihf.so cv2.so
$ cd ~

I skipped that because I have no idea where I have to create the link when I install this without virtualenvs. But it seems that I have to link it…

//edit: Key to success:

cd ~/opencv-4.0.0/build/lib/python3
sudo cp cv2.cpython-35m-arm-linux-gnueabihf.so /usr/local/lib/python3.5/dist-packages/cv2.so

oh, I didn’t know that you have a modul for it. But unfortunately it isn’t working on my Pi. Your modul doesn’t recognize a motion.

Do I have to uninstall the MMM-MotionDetector first?
Or do I need to run Face-Reco-DNN or the OCV3 version?

//edit: I think I know why it isn’t working. Maybe my display isn’t HDMI-CEC ready. I changed the command of your node_helper.js.
Default:

turnOn: function() {
		var self = this;
		exec('echo "on 0" | cec-client ' + this.config.comport + ' -s -d 1', function (error, stdout, stderr) {
			self.status = 'on';

My version:

turnOn: function() {
		var self = this;
		exec('vcgencmd display_power 1', function (error, stdout, stderr) {
			self.status = 'on';

Instead of sending a note to my display for standby I switch off the display_power. But I can’t wake up the display again. I think I have to use Face-Reco-DNN or Facial-Recognition-OCV3. Currently I don’t use them because I have to do the setup for the DNN version.

damn - 2nd try without a virtual environment.

@nischi: Is there a chance that you merge your module also with MMM-MotionDetector? Currently I use the camera to activate and deactive my screen and Google told me that it isn’t possible that 2 processes use the same camera. The suggested solution was to use a 2nd camera, merge both processes or stream the camera picture.
