MMM-RAIN-MAP (new: version 2.x)
-
I have a alpha version for a backend-generated (pre-rendered) map.
Are there any volunteers who would like to test it? (Please only people who can withstand high frustration :-D ) -
@Jalibu I can test it out on a virtual machine running raspbian for you if that helps :winking_face:
-
@Jalibu i can again
-
@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
-
@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 :love-you_gesture_light_skin_tone:
