Review: Perfect works with Alexa and my phone - This works just like I wanted. Setup Alexa to say what door opens on select device during select hours, so it doesn’t wake the kids but alerts me. It also goes off on my phone what is perfect because if I’m outside, I can still be notified. It is a little delayed like 20 seconds to say it on Alexa, but not a big deal. Very easy to install, had about 2 weeks now and really like it. The price is great too, was looking at the ring version of this but you have to have ring alarm and they are more pricey too. You do have to know what you are doing when ur setting up Alexa to alert you but it’s very basic in my eyes.
Review: Not reliable - Not great, it ran the automation twice out of 50 Times. No longer connected to Alexa for some odd reason. Not worth spending any more time Or effort on this.

This product works really well. I put it on my door and every time the doors open I get notification that the door was open in time. Good alarm system . All you need to do is download app… this is so good. I’m thinking to buy another one for my window.
