@oneartur unfortunately no.
The module uses rainviewer.com API. The free plan only offers history data.

I started to play around with windy.com and had good results on my MacBook for development, but windy’s map rendering is so heavy weight, that it did not really work stable on the raspberry pi.

I also find it a pity, that MMM-RAIN-MAP does not provide a forcast. Let me know, if you find a free dataprovider to enhance that.
