Wyze Home Monitoring - Ideas/Improvements for "Build My System" options

I am buying a second home monitoring system, creating a second account for a second location. The Build My System does not allow one to add things other than predetermined ones that do not include what I want to this order and as a consequence, I am told I will need to make two orders and thus pay two shipping charges. Come on folks – make your orders and forms customer friendly!

I had Wyze home monitoring for a year and it lapsed in May 2022. When I originally signed up, I was given all equipment for free: smart hub, keypad, etc. I am looking to renew or resubscribe to this service and see that there is an offer for a free smart hub. Well, I already have this and was told that there are no substitutions. Why can’t we substitute for something else like sensors?
