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

@sdetweil it’s strange… because I have some modules active

standard Calendar
MMM-CalendarEXT3
standard weather
MMM-Formula1
MMM-Growatt

is it an issue? Everythings seems ok except for startup (sometimes)

@sdetweil

it’s running

@sdetweil Yes, I’m using PM2

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

@sdetweil “compliments” ok.
when I’ll have some spare time, I’ll try.
Thank you

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 degrees

Is there a way to do it?
Thanks

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

@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.
Like half an hour ago or more
