Fred, sorry you are also having problems with your detection zone on the VDBv1. You are not alone.
Some months ago Wyze updated the Firmware to make the VDBv1 compatible with the HMS. When they did this thinks went all wonky. They eventually halted that Firmware update and also the next update that was supposed to fix it. They are working on a fix now.
I posted on this before. See this thread. There are also links there to other topics discussing the same.
