Siren suggestion?

Hi Guys,

Did a search but could not come up with much info. Any suggestions for a really loud siren that I can set up with either Acara motion sensors or Tapo motion sensors? And secondly, between the two systems, Aqara and Tapo, which would you guys suggest? The Tap costs less then half of Aqara where I live.

Any Siren (AC/DC) that fits your needs and a simple smart relay of your choice :golf:

Such thingies for a few dollars are already very loud (quite unpleasant to be near without ear protection :ear:)
