Thanks Abraham for contributing your finds! This can be a very welcoming community with everyone sharing thoughts and ideas openly.
I recently looked into this exact idea... See my thread below... I appreciate the brotherly caution many users bring to the table however...
As I looked for a 15-16 amp devices, I found these in the Amazon store... They look like they are exactly the same as the Aubess item you found on AliExpress.

Anyway, I ordered a few of them to play with. Half of them paired perfectly and worked as described pairing as a generic zigbee switch... The other half of my order would only pair as a "device" and had no functionality. Interestingly, although branded the same, they appeared to have different firmware on them. I suspect these devices are all made by the same manufacturer and then re-branded by many different sellers...
Anyway, just wanted to say thanks for your comments!
