Hi Guys, after going through the forum here, i think what fit my current needs is either Aqara A100 or Lockin S30 Pro. I've got a few questions though, for Lockin S30, am i able to generate OTP when i'm away from home? Let's say that i'm in office and my friend want to go into my house cause they forgot something, am i able to generate OTP to allow them access one time to my home? How would this work exactly, cause from what i can understand, S30 pro doesn't have a wifi connection. Can anyone clarify? Much thanks!
