What Is the Meross Smart WiFi Door & Window Sensor Kit and What Does It Do?
The Meross Smart WiFi Door & Window Sensor Kit is a battery-powered sensor system with a main sensor, sub-sensor, and included WiFi hub for monitoring doors and windows. It solves security concerns by detecting open or closed states and sending real-time alerts via app notifications for burglary prevention, child safety, or home automation. Commonly used on entry points like bedroom doors, garage doors, cabinets, or fridges, it triggers actions such as turning lights red on activation. The hub connects to 2.4GHz WiFi and communicates with sensors via 433MHz wireless, supporting up to 16 sensors with a 328ft range. Battery life lasts up to 18 months on a CR2450, and installation uses adhesive tape without tools. Compact sizes include 2.24 x 1.22 x 0.59 inches for the main sensor and 2.3 x 1.6 x 0.8 inches for the hub.
What Does the Meross Smart WiFi Door & Window Sensor Kit Work With? (Compatibility and Integrations)
The kit offers direct native integrations with Apple HomeKit, Amazon Alexa, Google Assistant, and Samsung SmartThings through the included Meross HomeKit Hub, which requires 2.4GHz WiFi and a Meross app account for initial setup. The hub bridges sensors to these ecosystems, enabling voice control like asking Siri for status updates and app-based automations such as linking to lights or plugs. No direct Matter or Thread support exists; HomeKit integration needs iOS 13 or later. Operations rely on cloud connectivity via the hub, with no local control option without it. Limitations include hub dependency for all functions, potential alerts from cloud reliance, and up to 16 sensors per hub.
Does the Meross Smart WiFi Door & Window Sensor Kit Work With Home Assistant?
No, it does not work natively with Home Assistant. The sensors use proprietary 433MHz protocol via the Meross WiFi hub, unsupported by standard Home Assistant integrations like ZHA, Zigbee2MQTT, Z-Wave JS, Matter, or HomeKit Controller. Cloud-based Meross integration may expose basic open/closed status and alerts, but it requires the hub, Meross account, and internet; no local control. Functionality is limited to binary sensor states without history export or advanced automations.
