Hi,
If you want to arm/disam the Xiaomi Gateway alarm system with NFC, please take a look at my Kickstarter project.
I plan to lauch the project in a few days. The Proof of concept is already working. I need raise few money to design a final product.
I’ll be glad to answer your questions.
Kind regards,

What has this to do with home assistant?
Dear Friend,
You are right. I changed the category. Hardware is more appropriate. My project is related with HA because I plan to integrate to HA with the presence functionality. (But this feature is not in the top priority for the moment)
Kind regards
