YoLink YS1604+3YS7704 Door and Window Sensor Kit, 3 Sensors with SpeakerHub

The YoLink YS1604+3YS7704 door and window sensor kit combines three contact sensors with a SpeakerHub for audible alerts. It is suited to monitoring several openings, with app control and a hub that the listing says can speak customized messages. The listing specifies 2.4 GHz Wi-Fi for the hub and LoRa for sensor communication, so this is not a hub-free sensor bundle.

What to know before buying

Listing details to confirm

The listing contains conflicting bundle and configuration details: the title and package description say three sensors plus a SpeakerHub, while the Color field says “3-pack without hub.” It also lists a maximum range of 620 meters, while feature copy claims up to 2,034 ft. in open air and customer feedback mentions up to 500 feet from sensor to hub. Confirm the selected package and treat range as dependent on conditions. The details table labels the alert type “Motion” even though the product is described as a door and window contact sensor. The listing says 2.4 GHz is required for the hub, while LoRa is the sensor technology, and does not clarify the exact networking setup.

Who is it for?

A good fit for

Households wanting door and window status alerts across three openings and audible or spoken notifications from a hub.
Buyers who prefer tape mounting and app-based sensor setup.
Users who want to monitor a freezer, cabinet, or other door where a left-open reminder may be useful.

Less suited to

Buyers seeking a sensor-only package without a hub, unless the selected listing variation explicitly confirms that configuration.
People who need a verified wireless range for a particular building layout or guaranteed notification timing.

Customer feedback highlights easy setup, prompt notifications, connectivity with Alexa, Home Assistant and IFTTT, and perceived usefulness for varied monitoring tasks. Those reports suit the kit's app-controlled, multi-sensor design, but do not establish a particular range or guarantee alert timing. The reported range differs from the listing's range claims, so buyers should consider their layout and connectivity needs rather than assume a fixed distance.

Positive themes

Customers report that setup is easy.
Feedback describes useful opening alerts and app or smart-home connectivity.

Frequently asked questions

What is listed as included in this kit?

The package description says it includes one YoLink SpeakerHub and three sensors, four products total. A separate Color field says “3-pack without hub,” so verify that the selected listing variation is the hub bundle.

Does this kit need a hub?

The described package includes a SpeakerHub, and the listing says full device supervision requires a hub. Its package details are inconsistent, so confirm the selected variation.

How do the sensors connect?

The listing identifies LoRa as the sensor technology and says a 2.4 GHz band is required. It does not fully explain the hub's network connection in the supplied details.

Can the SpeakerHub announce alerts?

The listing says it can play tones and alarms and read standard or customized messages using text-to-speech.

How long do the batteries last?

The listed battery-life claim is 5 years. The feature copy describes this as up to five years between battery changes, so actual life may depend on use.
