Not sure how best to implement this, but currently the plugin requires lat and long to be entered as separate fields. It would be good if we could have them combined, so that we could then use a variable to supply the coords. For example, you could do:
when connected to wifi, set %latlon to xx.xx,-yy.yy and then use %latlon elsewhere in Tasker (for example to do a sunset/sunrise lookup), and pass it to the plugin to also do a forced location fix.
This way you can have one Task which performs the update, and call it from different profiles.
