cuz you used it on the previous "smart home purchase"? this 20% coupon is only good 1 per account on a smart home purchase.

Coupon didn't show up for me on both a prime and non-prime account. Haven't bought any smart home items recently.

These can be wired to your existing system right? So if one goes off, they all go off? So I've always wondered then, why do you need a 3 pack? Shouldn't this one trigger your event, no matter which of your (non-smart) alarms goes off?

Edit: The product page advertises them as "interconnected", but reading the reviews, this is misleading. They cannot be connected to an existing system. How dumb.
