Hi,
That was the solution. I had forgotten “npm install” during the new installation. Thank you for your help.

@ayotrav
With the module MMM-GroveGestures you can use various gestures. In combination with the module MMM-NotificationTrigger a lot is possible. I use the combination to scroll, to continue scrolling while displaying images, to turn the monitor on and off, etc. Maybe this helps you.
By the way to all module developers, you are doing a great job. Thanks a lot!

@Sean Hello,
the error " Python script is terminated" I could actually fix by adjusting the i2c speed. Thanks for the tip.
The subsequent errors were caused by the NOAA module.
Thanks for the help.

@Sean
Thanks for the quick answer.
Last night it started correctly for once. That was after several restarts, no idea why it suddenly worked. Then I let the system run overnight, that was no problem.
I rebooted it earlier for a test. The error did not occur then, but the module does not react now. Therefore all modules are on the first page (use MMM-GroveGestures for the page change together with MMM-pages, MMM-page-indicator and MMM notification trigger which worked otherwise). Even a restart does not help at the moment. I have increased the speed of i2c.
python gesture_print.py works.
All modules seem to be loaded correctly. (see MagicMirror-out.log
below)
Is it maybe more a problem of MMM-pages?
Today I will test the system without MMM-pages and only with the clock, if MMM-GroveGestures works I will start the other modules bit by bit. Maybe I can identify a module that causes problems.

Hello everybody,
I’ve recently had a problem with the MMM-GroveGestures module. Besides, a great module!
I get the following messages in /MagicMirror-error.log.

A restart does not help.
I use a Raspberry Pi 3 Model B Rev 1.2

I use the following modules:
MMM-DWD weather warning; MMM NOAA; MMM-pages; MMM Remote Control; MMM buttons; MMM Grove Gestures; MMM notification trigger; MMM-PIR sensor; MMM-NASA; MMM-page-indicator; MMM-Public Transport Hafas

I would be very thankful for help.

@barnosch Thanks for your tip

Had the whole system rebuilt. Maybe I forgot this. I’ll test it this afternoon. I checked API Key several times, everything is OK
