Data from the official Eufy and YoLink sites.
2026 verdict
For anything outdoors or far from the house, the YoLink LoRa Smart Outdoor Contact Sensor is the stronger door and window sensor of this pair, and the more affordable one too.
It is IP63 weatherproof, rated for roughly five years on replaceable AA batteries, reaches gates and mailboxes up to a quarter mile away over LoRa, and carries a two year warranty against one. The Eufy Entry Sensor answers with the higher owner rating and deep integration with a eufy HomeBase, triggering eufy sirens, cameras and chimes with no monthly fee. Both need their own maker's hub to work at all. Choose the YoLink LoRa Smart Outdoor Contact Sensor for weatherproof, long-range, lower-cost coverage; pick the Eufy Entry Sensor if the higher owner rating and deep eufy ecosystem integration matter more for an indoor door.

What the differences mean
Weatherproofing and placement
The YoLink LoRa Smart Outdoor Contact Sensor is IP63 rated for indoor or outdoor use. The Eufy Entry Sensor carries no weather resistance and is meant to stay indoors.
Range
The YoLink LoRa Smart Outdoor Contact Sensor uses long-range LoRa, reliable at 300 to 800 feet from its hub even through wooded areas, for gates and mailboxes a home sensor cannot reach. The Eufy Entry Sensor talks to its HomeBase over a shorter sub-1GHz link built for inside one house.
Battery life
The YoLink LoRa Smart Outdoor Contact Sensor is rated around five years on a replaceable AA battery. The Eufy Entry Sensor runs on a CR123A rated around two years, though some owners get two to three.
Ecosystem and hub
The Eufy Entry Sensor triggers a eufy HomeBase's own siren plus a eufy camera's siren, recording and chimes. The YoLink LoRa Smart Outdoor Contact Sensor instead reaches Alexa, Home Assistant and IFTTT directly, with Apple HomeKit, SmartThings and Matter available through the separate YoLink Local Hub.
Warranty
The YoLink LoRa Smart Outdoor Contact Sensor carries a two year warranty. The Eufy Entry Sensor carries one.
Which one to buy if
- the sensor needs to survive weather on a gate or shed far from the house
It is IP63 weatherproof and reaches hundreds of feet over LoRa; the Eufy Entry Sensor has no weather resistance and a shorter range.
- you already run a eufy HomeBase and want a door to trigger a siren or camera
The Eufy Entry Sensor is built to trigger eufy sirens, camera recordings and chimes with no monthly fee.
- you want the longest possible stretch between battery changes
It is rated around five years on a AA battery against about two years for the Eufy Entry Sensor's CR123A.
- you want Apple HomeKit or SmartThings, even through an extra hub
The YoLink Local Hub bridges it to Matter; the Eufy Entry Sensor has no path to HomeKit, SmartThings or Matter at all.

What owners say
Owners of both sensors value how reliably each one reports open and closed with essentially no false alerts. Eufy Entry Sensor owners build their case around the eufy HomeBase: triggering the built-in siren, a camera's own siren and recording, and a door chime, all with no monthly fee, and several report units still working after four or five years on one battery. YoLink LoRa Smart Outdoor Contact Sensor owners buy it specifically for range, running it 300 to 800 feet from the hub even through wooded areas, and single out the open-reminder alert that warns when a gate is left open as the reason they bought it. Eufy owners wish for Apple HomeKit support that never arrived; YoLink owners note the battery compartment sticks on with tape only, with no screw holes, a weak point for a sensor meant to live outdoors.
