Other way is to define a popover class with a identifier. Like item name or something.  
Look at my heating widget.

> Hi @RowanS sorry here is a bug in the popover code. I define a identifier to control this proplem. Now the location props is required and this prop is the identifier if you use more than one widget. @Tallman I cant reproduce this error. Pls try again and check all needed and referenced items. all the best, Nico play_button V1.8.1
