Well, couple things, the distance involved and the fact that the sensors will all be non-Z-wave plus. I’m certainly open to suggestions to hub and mains-power repeater placement. If I can get away with just one, that would be great.
I was reading this… Maybe I’m missing something? The thread talks about Ring doorbell, Google Home, Alexa, etc. Don’t want/need all that. I am looking toward an easy end-user notification system.
