How to use webcore places in piston



1) Give a description of the problem
I try to use places (set in webcore seting) but Unable to find how! I tried to filled a variable with the current place to test and it stays not set. I tried $location : current place and with the webcore presence sensor:current place and nothing works…
I also integrated life 360 but it only allow presence for home, all other places are not usable…
Maybe it exist another handler or something?

2) What is the expected behaviour?
fill the variable with the current place

3) What is happening/not happening?
still empty
