They suggested you the best option,
but these are way powerful for what you really need for running a MM.
Clearly, more powerful=better
But on my experience I run a simple instance of MM on a Raspberry 3 A+, daily.
For simple instance I mean these modules: basic clock, CalendarEXT3, basic calendar, MM-Formula1 and a module for monitor the solar panel energy production.
So you don’t need very powerful machines, in my opinion.
The best advice is, as sdtweil said, USE a Raspberry power supply
NOT a simple charger

@sdetweil it could be. It’s a good card but it could have reached her lifespan. I’ll give it a try, thanks

RE: Performances on Pi 3A+
@sdetweil it’s strange… because I have some modules active
standard Calendar
MMM-CalendarEXT3
standard weather
MMM-Formula1
MMM-Growattis it an issue? Everythings seems ok except for startup (sometimes)

Performances on Pi 3A+
Hello,
I’m here to asking an help.In the past I’ve set up an MM and it works good.
I started using a PI 3A+ with 512mb of ram, after some months and some performance issues I switched it to a pi 3B+ with 1GB of ram.Honestly performance’s issues were not ram related, because the command “free” told me I have a lot of free mem but I switched anyway for “science purpose”
Anyway, on pi 3B+ it worked better.
After some months I decided to turn it back on a 3A+ for some reasons.
The 3B+ with a lot of ports is wasted on that project, 3A+ should be enuough and I’m right but some little problems appeared again.Tha major problem is at startup: sometimes it started with a black screen and cursor and I need to manually CTRL+R to make the interface show correctly.
It’s very strange, in my limited mind an issue like that is related to RAM but is not.
“Free” shows me a good amount of Free RAM.
Thanks

RE: Weather (temperature) based messages
@sdetweil “compliments” ok.
when I’ll have some spare time, I’ll try.
Thank you -
Weather (temperature) based messages
Hello,
I have an idea to show on my MM some weather or temperature based messages.
I’ll try to explain it well; where I live, especially during summer, temperature could change a lot from a day to another, like 12/18 degreees.
I wanna display a message for the home guests who say, for example:
“NO AC needed”
when temperature is under X degrees for the day
“AC allowed”
when T is more than X degreesIs there a way to do it?
Thanks -

@sdetweil Did it. Hope it solve my issue. Thanks

RE: MMM-Growatt
@mumblebaj
My module is working right now and I read you suggest to not upgrade it if it’s working but I’m interested about the “connection retry” function because sometimes (very rare) it stay still on a previous lecture.

@sdetweil
I’m sorry Sam, I didn’t figure out where I have to configure the
mmFetchTimeout. Where is it located? Thanks -
RE: Error in the calendar module check logs for more details
@sdetweil later I’ll try. The version is the last one

Error in the calendar module check logs for more details
Hello,
I have a problem related to the basic calendar module.
I use the private.ics from google but sometimes it can’t fetch data.
It doesn’t happen regularly, only sometimes but this error keep me to keep the keyboard connected for use the CTRL+R function everytime it happen.
It’s annoying because I hope to forget it completely and just using MM.
I can reproduce the issue with CTRL+R, every 7/8 refreshes it happen.
I could not refresh it forever but MM turn off and on every day so… it happen.My question is: is it a normal behaviour from google or is there something I did that cause the behaviour?
I checked pihole also, thinking it could cause issues but it seem not related to it.As calendar I use the basic one and the EXT3
Here is the log, thanks

RE: [ERROR] _ is not defined
@rkorell Again, thank you Sam.
I know what you mean, I usually act as you said.
I like to help other, in the subject where I have knowledge.
So, thank you again -
RE: [ERROR] _ is not defined
@sdetweil Ok but I wanna just offer a coffe for your kind and your time spent with that.
Do you suggest me to fix the old magic mirror folder or just rm it?

RE: [ERROR] _ is not defined
@sdetweil
Sam… I don’t know how to saying it.
I figure out the issue.After your last message I tried what you suggest.
With the default cfg I had no errors, with mine I had errors.So I checked again and again the config…
and I find an underscore _ right at the start of the confignpm config:check told me “no syntax errors” and that confusing me.
When I edit it I use nano editor
I do “sudo nano config.js” and I press CTRL + _ to jump at the 250 line.
Might be one of the latest time I opened it and press _ a bit faster than CTRL and I add it for error.In addition I notice that when I open config.js with nano editor the green cursor is, clearly, at the start of the first line… EXACTLY on the undescore _ and it hides it.
I’m really sorry for bothering you with that.
How can I buy you a coffee ?
Thanks -
