The current line of sensors does require a bridge, which must be inserted into aV2 or Pan Cam. The Base for the outdoor cam generates its own signals just for the WOC-it does not connect to the Sensor line.
Wyze is however releasing a new sensor line with the upcoming Home Monitoring system. I would suggest waiting until that is released to see how it all integrates.
Thanks for the reply I’m just looking at solutions for smart things around the house to help my wife out who is disabled, anything I can put in place to help is a bonus
