MMM-RAIN-MAP

plainbroke

Anyone else have MMM-RAIN-MAP all the sudden stop working?
It actually locked up my MM . OR do I have to many modules running under MMM-pages? Approximately 48.

Rpi 4 8gb ram running water cooler and nvme-sata 128gb power supply is the pi5 version.

Hi @plainbroke,

yes, this is very likely API rate limiting (HTTP 429 errors) from RainViewer. The module was making too many requests with default settings.

I recommend to update to the latest release v2.11.0 which includes:

Optimized defaults
Exponential backoff retry logic for 429 errors
Better error handling

The module is working for me, but since today, the two lowest of my four zoom levels seem to have stopped working (no change after updating).

I don’t see any 429 errors in the logs.

But let’s just wait and see; it might work again tomorrow…

@karsten13 Thanks for that feedback! I can’t reproduce the issue with low zoom levels - they’re working fine here with the latest version 🤔 I’m curious to hear your outcome tomorrow.

Thank you for the update.
Now MM boots up and fully loads.
Before MM was hanging at load up of all the modules.
Just have to do a little resizing so it fits the screen again…
Thank you again…

MMM-RAIN-MAP itself is usually pretty light, but running around 48 modules under MMM-Pages can definitely cause freezes, especially after updates. Check the MagicMirror logs to see which module is throwing errors, and try disabling MMM-RAIN-MAP or a few other modules one by one to isolate it. It’s more likely a module conflict or resource issue than the Pi hardware.

they are definitely gone …

I used for several years

        mapPositions: [
          { lat: ${LAT}, lng: ${LON}, zoom: 9, loops: 1 },
          { lat: ${LAT}, lng: ${LON}, zoom: 8, loops: 1 },
          { lat: ${LAT}, lng: ${LON}, zoom: 7, loops: 1 },
          { lat: ${LAT}, lng: ${LON}, zoom: 6, loops: 1 },
        ],

and now found in their docs Maximum zoom level is 7.

Another restriction is that there is no forecast anymore (as already stated in the module readme).

That’s a shame, it unfortunately devalues the module.

@karsten13 Thanks for investigating! It’s really a shame. I’ll update the docs.

colorScheme seems to be useless too, the docs only mention 2 which is the default in the module, if I try other values there is no difference.
