Review on Wireless Smart Siren Alarm For Home Security With 110 DB Volume, Panic Alert, Remote Control, And Compatibility With Alexa, Google, Home Assistant, IFTTT - Requires Hub by Brandon Carr

I’m totally blind! The first thing I noticed about this when I took it out of the box. I noticed a switch on the left side of it and that it had a screw hole on the back to mount it on a wall. I next felt around on the back and found the battery cover. I wondered what the slide switch was for being it has 4 point altogether. So I put 2 AA batteries in it and nothing happened. So I slide the switch up one spot and the siren sounded. I slid it up another spot and the siren got louder! And the top spot is the loudest setting. I really like that. Makes it easy for a totally blind person to be able to set the volume without having to guess how to set the volume.I also noticed that the Micro USB port is on the left side as well. My own thinking is I think that the port really should have been on the bottom. That away when it is put on a wall, the cable comes out the bottom and not the left side.On the front of the unit is a button in the middle. This button looks to manually start or stop the siren.Took the batteries back out of it and then scanned the QR code on the siren and plugged it into USB power and the unit came online to the hub. Then I put the batteries back in and plugged it back into USB power.The rest of the stuff as far as I can tell, needs to be done from within the App. Looks like you can set the siren to sound anyware from 10 seconds to never shut off.You can also control the siren with Alexa if you have your YoLink account connected up to Alexa. Alexa turn on Siren. Alexa turn off siren. You can also use it in Alexa Routines as well.The YoLink App. As far as automation needs improvement for a totally blind person to use that function of the App. There are unlabeled button in the screen that make it so a totally blind person trying to setup automation for the siren to have to do it by trial and error. But I did get it done. I currently have it setup to turn on the siren when the motion detector that is in the mailbox triggers. It is responcive when motion is detected. It triggers about 3 seconds before the Alexa routine announces that the mailbox door is open!
