Hi there,
i am using homeassistant quite a while now and got really interested in doing more data visualisation. Therefore i managed to get my Roomba 860 working really nice in Homeassistant and i can see the coordinates attribute as own template. it consists of 3 pairs of date:
-43, 50, -98 - as I figured out ist Y/X and direction-coordinates.
Now I get the coordinates attribute like “-43, 50, -98” - but how can I split the values to get an value-template for x, y and z standalone? So I could use ist to get a movingmap via a simply picture-element floorplan 
Is there any chance, to simply read the comma-limited values in seperated variables oder to template each of the values?
