MMM-RAIN-MAP (new: version 2.x)

Fozi

@rubenix I’ve disabled yesterday all 6 modules, but unfortunatelly the situation didn’t improve. The memory consumption was still increasing over the time and within 1-2 hrs. the MM froze. I guess I have to do the brute force method and disable all modules and enable them one by one.

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 :-D
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 pause ;-)

Thanks 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

Jalibu

@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)/¯

rubenix

@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 :love-you_gesture_light_skin_tone:

@rubenix u can make the swap space bigger too, helps in some environments

rubenix

@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.

requiemmg

Okay, for now I will not switch to a 4gb version. So I need to remember this one for “later”. Thanks.

I just tried this out. Thank you for the excellent module! Exactly what I was looking for.

Now if I could just get a dark theme going. I’m cool with the rain being in color, but it would be nice if I could figure out how to get the roads & state borders to only be outlines.

@Jalibu Just tried it out and it works fantastic wit OSM. Great job! :clapping_hands_medium-light_skin_tone: Many thanks

Hi @Jalibu!

This module is really amazing! Thank you so much!

Maybe you can help me with one issue: The map doesn’t center correctly on my Mirror… Have I done something wrong:

        {
            module: "MMM-RAIN-MAP",
            position: "bottom_right",
            config: {

                displayTime: true,
