python - QGIS using the heatmapplugin from the console

I have to make a lot of heatmaps from csv's. Therefore I'm making a python script to run in the console.

So far I can load csv's and save them as shapefiles. To get to the heatmapplugin I'm using the following code:

rasterMenu = qgis.utils.iface.rasterMenu()
for rasterMenuItem in rasterMenu.actions():
    if 'Heatmap' in rasterMenuItem.text():
    heatmapMenu = rasterMenuItem

    for heatmapMenuItem in heatmapMenu.menu().actions():
        print heatmapMenuItem

        if 'Heatmap' in heatmapMenuItem.text():
            heatmapMenuItem.trigger()

Now I'm stuck. Does somebody know how to select the heatmap menu and enter the correct variables from the console?

I finally figured it out!

Instead of the heatmapplugin I used the kernel density estimation algorithm:

import processing
processing.runandload("saga:kerneldensityestimation", "path/to/shapefile.shp", "name of the colums with weigths", radius, 0, 0, None, celsize, "path/to/raster.tif")
