Hello,
my magic mirror displays at the top of the screen that an update is to be done for the MMM-Jast and MMM-DHT-Sensor modules but on the module pages (https://github.com/ryck/MMM-DHT-Sensor and https://github.com/jalibu/MMM-Jast) it is not indicated how to do the updates. .

How to update these 2 modules ?

@mann “Does the PI 4 support turning USB power off and on in software at all? If it does, how to do it?” : I don’t understand what you are telling me, so what should I do?

the original power supply was 3A which I changed because I had the message, I replaced it with several 5V 2A and sometimes I find the message. I haven’t had the message since last night…

I bought this model :

I have changed the power supply several times and I often have this display at the top right

what power supply do you recommend ?

any solutions ?

I do not remember anymore how to post the pm2 logs

@sdetweil as you told me, I do cd ~/MagicMirror/modules/modulename for each module.
I found an error in the last module : MMM-WeatherOrNot, a module that I no longer use so I deleted it with the command : cd ~ / MagicMirror and rm -rf modules / MMM-WeatherOrNot then i redid pm2 save and pm2 start 0 and turned the MM off and on again with ~ 1 minute but I still have a black screen and an electron problem.
what to do ?

I do this for the first modul :

pi@raspberrypi:~ $ cd ~/MagicMirror/modules/MMM-DHT-Sensor
pi@raspberrypi:~/MagicMirror/modules/MMM-DHT-Sensor $ ls package.json
package.json
pi@raspberrypi:~/MagicMirror/modules/MMM-DHT-Sensor $ 

i do this : npm init -y ?
