Please help to resolve a confusion between KS200M vs KS220M vs ES20M
As I understand, KS220M is a smart switch with motion and dimmer, KS200M is a smart switch with motion only and no idea what is ES20M
There is no product page for KS200M (however it's image is present on KS220M product page, at the bottom https://www.kasasmart.com/us/products/smart-switches/productks220m), it will be nice to know how its specification as well.

Thank you
