Everything you need to get started: one SpeakerHub, our unique, audio, talking (text-to-speech) hub, and (3) Door Sensors. Batteries are included and preinstalled, good for up to 5 years between battery changes. 2.4 GHz band, only, required. Supports 300+ devices from our full product line. Add more hubs for large homes, high-rise condo buildings, etc. - LET'S HEAR IT for SpeakerHub! Your SpeakerHub can play from a library of sounds and tones, from a chime tone to a burglar alarm siren. It can even play your uploaded MP3 files! But never before has your hub talked to you! Now, hear your important messages in clear text-to-speech messages. Let it read out the standard alerts, or customize the message; it's up to you! - WHY PAY A MONTHLY FEE, when you can secure it for free? Self-monitor and save when you take advantage of our many ways to be notified of alarms and off-normal events in and around your home or business. See "Know Now!" for more information! - THAT WAS EASY! Installs in moments: scan the sensor's QR code, give it a name, peel off the pre-applied 3M brand mounting tape protective plastic, press the sensor and magnet to the door and frame, and you have added security to your home or business! - MORE THAN JUST A DOOR ALARM! Place a sensor on each exterior door and window to 'Protect Your Perimeter' Activate and control lighting. Place a sensor on your fridge/freezer door or lid and know if it was left open, to prevent food loss. Track activity in your home or business. Keep an eye on children and elderly loved-ones. Use the sensors to protect liquor & medicine cabinets, gun safes, storage lockers & boxes. - DOOR AJAR!

Even if the internet is out and the power is down, they will carry out their paired actions. Pair your door sensors to a Siren Alarm, then turn it off when you want to "disarm" your system. Use a SirenFob or FlexFob to control your siren. Make your own custom security system! - DON'T TRY THIS WITH WiFi! LoRa is short for Long-Range. Boasting up to a quarter-mile open-air range, and operating at the 900 MHz band, YoLink devices can be placed where your WiFi probably can't go, such as in basements, separate buildings, even on RVs and boats stored on your property! Prepare to be pleasantly surprised! - What’s Included: This package includes 1 YoLink Hub and 3 Sensors—4 items total. The “Number of Items: 4 Pack” refers to the four individual products in the package, not four sensors. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0BZ88QB5P | | Alert Type | Motion Only | | Battery Average Life | 5 years | | Battery Cell Type | Alkaline | | Best Sellers Rank | #120,568 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #126 in Home Security Door & Window Sensors | | Brand | YoLink | | Built-In Media | Detector | | Color | 3-pack without hub | | Colour | 3-pack without hub | | Compatible Devices | Smartphone, Tablet | | Compatible devices | Smartphone, Tablet | | Connectivity Technology | Wireless | | Connectivity technology | Wireless | | Control Method | App, Voice | | Customer Reviews | 4.6 out of 5 stars 658 Reviews | | Installation Method | Self-Adhesive | | Item Dimensions | 8 x 8 x 11 centimeters | | Item Type Name | Door Sensor | | Item Weight | 66 Grams | | Item dimensions L x W x H | 8 x 8 x 11 centimeters | | Manufacturer | YoLink | | Maximum Range | 400 Meters | | Mfr Part Number | YS7704-UC*3 | | Model Number | YS1604+3YS7704 | | Power Source | Battery Powered | | Power source | Battery Powered | | Sensor Technology | LoRa | | UPC | 810121540510 | | Unit Count | 4.0 Count | | Voltage | 1.5 Volts (DC) | ## Product Details - **Brand:** YoLink - **Colour:** 3-pack without hub - **Power source:** Battery Powered - **Compatible devices:** Smartphone, Tablet - **Item dimensions L x W x H:** 8 x 8 x 11 centimeters ## Images ![YoLink LoRa 1/4 Mile Longest Range Smart Window & Door Sensor, Door Left Open Reminders, Alexa, IFTTT, Home Assistant, 3-Pack (Hub Included) - Image 1](https://m.media-amazon.com/images/I/619HJ7y-1PL.jpg) ![YoLink LoRa 1/4 Mile Longest Range Smart Window & Door Sensor, Door Left Open Reminders, Alexa, IFTTT, Home Assistant, 3-Pack (Hub Included) - Image 2](https://m.media-amazon.com/images/I/71feWHGQWBL.jpg) ![YoLink LoRa 1/4 Mile Longest Range Smart Window & Door Sensor, Door Left Open Reminders, Alexa, IFTTT, Home Assistant, 3-Pack (Hub Included) - Image 3](https://m.media-amazon.com/images/I/71cTMQHCxAL.jpg) ![YoLink LoRa 1/4 Mile Longest Range Smart Window & Door Sensor, Door Left Open Reminders, Alexa, IFTTT, Home Assistant, 3-Pack (Hub Included) - Image 4](https://m.media-amazon.com/images/I/71UBBOwgPgL.jpg) ![YoLink LoRa 1/4 Mile Longest Range Smart Window & Door Sensor, Door Left Open Reminders, Alexa, IFTTT, Home Assistant, 3-Pack (Hub Included) - Image 5](https://m.media-amazon.com/images/I/71gWBK6GrwL.jpg) ## Available Options This product comes in different **Style** options. ## Questions & Answers **Q: Will it discreetly let me know if house door is open? Or is it an alarm that people walking by outside can hear?** A: You can set it to text you or to have the hub alarm inside the house go off. My hub is in my 2nd floor bedroom and alarms on on my doors on 1st floor. So people opening the doors don't hear it I did that because I have an dementia patient at home and it notifies me if they try to leave house when I am sleeping but doesn't scare them **Q: Can app alert you every time do is opened?** A: Yes, you can set up notifications in the app **Q: I can not get the door sensors to bind . i have the app and hub successfully connected to wifi. door sensors blink one red light with button is pushed** A: Read the QR code on the sensor with your app first. **Q: Can the hub play a siren sound if the door opens or do you have to buy the seperate siren? I want to get a notice on my phone and an alarm sound.** A: The SpeakerHub can play a siren sound, but keep in mind it is not a loudspeaker (like our sirens are). The sound level is closer to an Echo Dot; it may not be heard throughout your home. But I have seen the SpeakerHub placeed in foyers and closer to the door locations, where it should be heard very well. This is also a good location, because you can have the SpeakerHub say "system armed" and "system disarmed" as you leave or arrive through that door. You should also take a look at our FlexFob and AlarmFob. https://www.amazon.com/dp/B0978V4WQC?ref=myi_title_dp&th=1 https://www.amazon.com/dp/B092M1QQ5M?ref=myi_title_dp&th=1 And here is our loudest siren: https://www.amazon.com/dp/B0BZHPQ1PK?ref=myi_title_dp&th=1 Enjoy!

For reference I have 16 as Door Sensors and 20 as Window Sensors as well as 1 I rigged for use on a baby gate for a total of 37 Door/Window Sensors Yolinks door sensors, like any technology, come with their own set of advantages and disadvantages. Here’s a breakdown: Pros: Security Enhancement: They provide an additional layer of security by alerting you when doors are opened or closed, deterring intruders or notifying you of potential threats. Affordability: Compared to systems like Vivint or ADT, which have highly priced devices, Yolinks sensors are more manageable, especially when purchased in multipacks. Convenience: They integrate with smart home systems, allowing remote monitoring via smartphone apps or other devices. You're not tied to a specific security system; cancellation doesn’t render the sensors unusable. Automation: Integration with smart home systems enables automation, such as triggering lights or cameras when a door sensor is activated. Ease of Installation: Designed for easy DIY installation, saving money on professional fees. Battery Operated: Long-lasting battery power ensures functionality even during power outages. Cons: Hub Speaker Limitations: While I appreciate they work with a hub, multiple hubs are needed for full-home coverage, especially for alerting open doors like those leading to a pool. It would be beneficial if notifications could be sent through Alexa directly without setting up routines, akin to how the LG Washtower notifies via Alexa. Initial Cost: There can be a significant upfront cost to purchase and set up a network of door sensors, especially for comprehensive coverage in large homes. Compatibility Challenges: Ensuring compatibility with existing smart home systems or security setups can be challenging, potentially requiring additional equipment or adapters. They may not integrate well with other alarm systems. Color: They only come in white. I ended up spray painting mine since all of my doors and windows are black. --- ## 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.jp/products/522257756-yolink-lora-1-4-mile-longest-range-smart-window-door](https://www.desertcart.jp/products/522257756-yolink-lora-1-4-mile-longest-range-smart-window-door) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-08-26*
