Eufy Entry Sensor vs Sonoff SenseGuard DW Gen2

No. Eufy Entry Sensor requires a eufy HomeBase, which it reaches over a sub-1 GHz link, and it has no Alexa, Google Home, HomeKit or Matter support. Sonoff SenseGuard DW Gen2 needs a Zigbee hub, but that can be Home Assistant, SmartThings or any standard Zigbee coordinator.

Within eufy Security it sets off the HomeBase siren and camera sirens, starts recordings and plays an entry chime, with home, away and night modes and no monthly fee. Sonoff SenseGuard DW Gen2 triggers whatever your hub supports, from Home Assistant scripts to Alexa routines.

Eufy Entry Sensor uses a CR123A that owners report lasting two to three years, sometimes longer. Sonoff SenseGuard DW Gen2 uses two AAA cells rated for about three years, which are cheaper and easier to source than the less common CR123A.

Sonoff SenseGuard DW Gen2, which includes a tamper alert alongside low-battery warnings and 90 days of history. Eufy Entry Sensor has no tamper alerting documented, and owners note its magnet housing is somewhat flimsy and the battery cover can pop off if mounted on the door.

Households already running a eufy HomeBase with eufy cameras, who want fast, subscription-free entry alerts and chimes with excellent battery life. If you want a sensor that answers to Home Assistant, SmartThings or Alexa directly, Sonoff SenseGuard DW Gen2 is the more flexible option.
