Bigbruin.com reviewed the ZOOZ Z-Wave Plus Indoor Siren ZSE01
A quote from the article:
The ZOOZ Z-Wave Plus Indoor Siren ZSE01 is a great choice for those looking to add a siren to the their smart home ecosystem. It is fairly easy to connect, has a variety of mounting options, and functions just as you would expect. The handful of things that really drew me to it are the fact that it is AC powered with battery backup, features the benefits of Z-Wave Plus, and when plugged in to AC power it will function as a Z-Wave repeater.ZOOZ Z-Wave Plus Indoor Siren ZSE01 Review
