Frient Model SMSZB-120 Feature Questions

Hi guys,

I‘ve to replace my smoke sensors next year 2023 and looking for some new smart ones. I‘ve found these Frient smoke sensors.

My questions before buying several one:

  1. Can the alarm be disabled via Phoscon App/API?
  2. Any experiences about the battery lifetime?
  3. Any experiences about wrong alarms?

Wish you happy new year and thank you for sharing your thoughts.
