Question about first setup


Currently looking on creating my first home assistant lab and wanted to see if someone could shed some light,

Currently i have a small home lab and wanted to implement monitoring of Smoke/temperature detector and water detector,

I was reading a bit and first i would need to install HA on a VM, then buy a gateway device which i think it would be this Aeotek Z-Stick (correct me if im wrong)

and for the sensor would be this

Thank you

Sounds like a good plan - so far so good. What is your concern?

Thank you for the reply, just wanted to know if anyone else has had the same setup and went well
