Please read the thread that I linked to. As I said, there are some quirks as far as how it works. It’s all discussed in that thread.
Thanks, before I read yours, I tried again and it worked.
I realized each new simulated contact sensor didn’t have Amazon Alexa in its SmartApps tab section. I went to Amazon Alexa SmartApps to disable allow Alexa to access all devices, scenes and routines then re-enable it then my fake contact sensors are authorized so now everything work great!!!
