Smart door and window sensors are a simple way to monitor entry points in your home. They can send smartphone alerts, trigger smart lights, or sound an alarm when a door or window opens.
Choosing the best smart door window sensor depends on your existing smart home ecosystem, the range you need, and whether you prefer a system with a dedicated hub. We compared the listed specifications and features of five popular sensor packs to help you find the right fit. We have not tested these products ourselves.
Our Picks at a Glance
We selected these five products by comparing their listed specs, including communication protocol, battery life, hub requirements, and smart home compatibility. Check each product listing for the current price and full details.

How to Choose
When selecting a smart door and window sensor, consider the following factors based on the specifications provided by the manufacturers.
Hub Required or Hubless
Some sensors, like the Aqara, YoLink, Tapo, and SONOFF, require a hub to connect to your network. The YoLink and Tapo kits include a hub, while the Aqara and SONOFF require a separate purchase. The GoveeLife sensor needs other GoveeLife equipment (sold separately) on a 2.4 GHz Wi-Fi network and only works within the GoveeLife ecosystem.
Communication Protocol
The protocol affects range and compatibility. Aqara and SONOFF use Zigbee. YoLink uses LoRa for very long range. Tapo uses a Sub-G protocol. GoveeLife pairs with other GoveeLife devices over 2.4 GHz Wi-Fi. Your choice may depend on whether you have an existing Zigbee hub or prefer a standalone system.
Battery Life and Power Source
Battery life varies significantly. YoLink claims up to 5 years of battery life. Tapo lists an average battery life of 2 years. GoveeLife lists a battery life of 4 months. Check the product listing for the specific battery type required; for example, the Tapo hub uses 3 C batteries, while the SONOFF sensor uses 2 AAA batteries.
Smart Home Compatibility
Check which voice assistants and platforms are supported. Aqara works with Apple HomeKit and Alexa. Tapo works with Alexa, Google Home, and Matter. SONOFF works with Alexa, Home Assistant, and SmartThings. YoLink works with its own app and hub. GoveeLife does not support Alexa or Google Assistant.
