default calendar fetching issues

sdetweil

ok, on the right branch

yes, when run with pm2, then pm2 logs is the way…

there are two sections of the output

the .error(stderr) and .out(stdout)

can you look in the .out?

the folder for the pm2 logs is

~/.pm2/logs

note the leading dot on .pm2

@sdetweil

It’s very long.

I checked the end paragraph ad I saw just errors from growatt module.
Do I have to search something in particular?

Do I have to search something in particular?

I do not know

can you recreate this if un restart MagicMirror? does it always fail in the morning?

pm2 is really for production use,

if you can repeat it

pm2 stop all
cd ~/MagicMirror
npm start &>somefile.txt

wait til failure
ctrl-q on MagicMirror screen
then examine the somefile.txt

Recreated 2 times.

[2025-03-19 22:47:20.696] [LOG] Stopping module helper: calendar

Honestly… I don’t see nothing strange.
But when this error appear, if I left MM on for a day, it wont load calendar entries.

I have to restart it one or more time till it show entries

sdetweil

@nowayto ok, disable the updatenotification module in config.js

add

disabled:true,
after the
module:line

nowayto

@sdetweil
I did it.
I usually put the “disabled: true” before the module name line, instead of after
Is it different?

sdetweil

@nowayto no. just some users dont know what i mean

nowayto

@sdetweil
behaviour seems the same. I suspect this, could this issues be related to the raspberry pi 3 computing capacity? could it be not enough?

Is there a way to delay the pm2 automatic startup.
For example I though to try a delay of 1-2 minutes so:
1- raspbian startup
2- delay of 1-2 minutes to make sure all the services are up and the cpu is idle
3- mm startup
4- if it’s possible, I will add a delay to the modules startup also, maybe 20 seconds between every module loading

Honestly I checked his capacity a lot of times using the htop, free and cpu temperature command.
With my amazement I see everytime an amount of free memory, low cpu load and good cpu temp (like 40 to 50 degrees)

But if there is a way to delay everything, I’ll just check if with a “calmly” startup It will go better

sdetweil

@nowayto i do not know on pm2

you could put a sleep 120
in the mm.sh to wait a while

how is swap space?

free -m

pi02w only has 512mb

nowayto

@sdetweil
Yes I agree, the memory is very limiting.
Although mine is a Pi3 model A, but the memory is 512mb like the pi02w.
When I started the project I had something different in my mind and now I’m pushing it to the limit.

But as I said I checked everytime the CPU temperature, memory and generally resources usage from “htop” command.

This morning MM started with calendar error, I did a “pm2 restart mm” and goes OK.

Now I put “sleep 120” inside mm.sh as first line
I restarted it now

Memory BEFORE restart was this
total used free shared buff/cache available
Mem: 427 156 90 70 179 147
Swap: 1023 231 792

Not so good but not so bad, same time.

I’ll check if this delay could help.
Is there a way to put a little delay between the loading of every module ? Maybe 5/10 seconds, I though it could be very helpful on a limited machine like mine :)
