MMM-RAIN-MAP (new: version 2.x)
-
The serverside prerendering works in theory. The recording is just 2-4 Megabytes and the playback on the frontend consumes nearly no additional computing resources.
The little problem is that prerendering is kind of ultra heavy
My Raspi 3 takes more than a minute for that (with only a few additional modules running) and takes >60MB memory for that.
For those of you having problems due to limited resources with live rendering, the prerendering won’t be the answer I guess -
I FOUND THE “CULPRIT”!!
Yesterday I tinkered around with a module I tried some time ago (MMM-TextClock) and deactivate MMM-google-routes, as I knew the didn’t play well together. In that context I enabled MMM-RAIN-MAP again, just to see if that would have any effect if MMM-google-routes was disabled.
And Bingo!
Since yesterday evening I had no crash or freeze on my MM. Also the memory consumption appears normal and the processor load is between 5%-20% on average (RPi 3b+)I’ll keep MMM-google-routes disabled for now, as I gives me no real added value at the moment.
And to be clear, it is is a beautiful module and I love it, but I have no current use case for it. I ran it from the very beginning of my MM build without any issues and it is an eye catcher, too. But in favour of MMM-TextClock and MMM-RAIN-MAP we’ll have a pauseThanks to all of you and @Jalibu for helping me!

Hi @jalibu,
I really like this module, but I fear that the memory issue still persists.
Just cloned the repo, the module runs fine for some minutes or up to one hour, then the Raspi freezes. I am running on a 1GB 3B+ with 4 pages.
Anything you can do about it? -
@requiemmg since I updated the pi to a Pi 4 4GB have no issues at all…came from a pi3 1GB too
-
@requiemmg
yepp, as @rubenix mentioned, 1GB memory is unfortunately too little
On my Raspi 4, 4GB it just works perfectly fine.I already tried to optimize the rendering to get it working with limited resources, but without success ¯\(ツ)/¯
-
@Jalibu & @requiemmg was tempted to go for the 8GB one, but I can confirm 4Gb is more than enought; go for it and use the pi3 for another project
-
@rubenix u can make the swap space bigger too, helps in some environments
-
@sdetweil i agree with that and sure it helps; but a pi 4 4Gb goes so smoth!!
pi3 1gb its ok for a simple magic mirror; for a complex one with transitions / animations it needs more gauge! -
Great module. It’s running fantastically on my PI4.
-
Okay, for now I will not switch to a 4gb version. So I need to remember this one for “later”. Thanks.
