Wi-Fi Thermometer Hygrometer WiFi Door Sensor Wi-Fi PIR Motion Sensor Smart Hub & IR RF Remote Smart Siren & Smoke Detectors 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: Device canno connect- DEFECTIVE - DO NOT BUY! Device defective and you’ll need to pay for return. Attempted every available option along with using the manufacturer help desk. The manufacturer concluded the device is defective yet there isn’t a way to get a refund without finding a Khols or paying for UPS. Which is half the cost of this product. I use many other WiFi devices and can connect but not this one. ## Features - APP ALERTS ON YOUR PHONE: Wifi door sensor, "Tuya Smart" or "Smart Life" APP control. No hub required and No fees charge.

The small case is just a magnet. You can open it and look. You can substitute any rare earth magnet for this case if your door frame does not have room for it. Just drill a very shallow hole the same diameter as your magnet and glue the magnet in. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.br/products/278325004-wifi-door-sensor](https://www.desertcart.com.br/products/278325004-wifi-door-sensor) --- *Product available on Desertcart Brazil* *Store origin: BR* *Last updated: 2026-06-18*
