Can somebody tell me why I would need a siren if 8 alexas in my house would warn me of a leak?

Yes, because when the internet is down or got the power outage, all the Alexa will not work. But the water leak can trigger the siren without internet. If you installed the batteries in the siren, even there is power outage, the water leak can trigger the siren. Thanks!

Does the siren stay audible after it is triggered until someone turns it off?

YoLink Siren Alarm will automatically disable the alarm according to the Alarm Duration setting via YoLink APP, the default setting is 30 seconds. And other ways to turn off the Siren Alarm are as below. 1, Press the SET button on the Siren Alarm. 2, Click Disable button in YoLink App. 3, Press the relative OFF button on the YoLink Remote (sold separately).

Is there a way to have door sensor trigger siren when door is left open for x amount of time? Also, can closed door sensor shut off siren?

You can set the siren to go off @ 10 seconds and up. You can set it up to go off when open and/or closed.

How any sensors can be connected to hub and alarm

One YoLink Hub supports 200 YoLink devices in real test. And you can add one or more YoLink Hub to expand signal coverage. One YoLink Siren supports up to 128 YoLink devices in total.
