Review on Aeotec Siren 6: Powerful Z-Wave Speaker & Light Security Intruder Alarm with Backup Battery by Dragan Nelson

Want the alarm to go off randomly, with random tones and any volume? NO, nobody does that! It's rubbish as many others have said. It's outrageous that SmartThings claims to be compatible! "The built-in handler is practically useless," says the author of the third-party device handler. It will take you a dozen hours to find the right version of the client-written device handler, install it, and play around with it to do anything at all. THEN you can expect it to behave randomly. The sound happens to be soft or shrill. I've never been so angry! So much wasted time and money. All these bad reviews have a reason! Stay clean.
