Newbie qquestion


I stumbled over gbridge the other day and discovered that this is what I’ve been looking for a long time and seems to be awesome soofar. After an initial trial and terror I’ve now managed to write a small testprogram in B4J ( amazing software if you do programming on a hobby basis) where I can communicate to Google home with a few test onoff devices. But I have a question: If i set a new status from test program the icon for that device don’t change until I ask Google for the status. Is there a way to force the icon for a device in Google home to change from onoff without asking for the status ?
