Smart Door & Window Sensor. Instant phone alerts whenever a door or window opens or closes — compatible with the Tuya Smart ecosystem. Available in WiFi (no hub needed) and ZigBee (hub required) versions. Compact, discreet, and easy to install on any frame. Model ZMWL080. 2Connectivity Options WiFiNo Hub Needed ZigBeeHub-Based Low Power TuyaEcosystem Compatible Instant Phone AlertsKnow the moment it opens WiFi — No HubConnect directly to your router ZigBee — Low PowerFor existing ZigBee hub setups Tuya Smart AppRemote monitoring & automations 01Instant Alerts — Know the Moment It OpensThe sensor sends an immediate notification to your phone whenever a door or window is opened or closed — so you know in real time, whether you’re in another room or away from home entirely. The kind of awareness that makes a meaningful difference to home security without requiring a full alarm system, and that’s useful for monitoring entry points, keeping track of children, or simply knowing when someone arrives. Every open and close event is logged with a timestamp in the app, giving you a full history of activity at each sensor location. 02WiFi Version — No Hub RequiredThe WiFi version connects directly to your home network — no additional hub or gateway required, just your existing WiFi router and the Tuya Smart app. The simplest way to get started with smart home security monitoring without investing in additional infrastructure. Ideal for anyone who wants a single sensor up and running quickly without committing to a broader smart home ecosystem. Setup takes a few minutes through the app; the sensor pairs to your network and starts sending alerts immediately. 03ZigBee Version — Hub-Based, Lower PowerThe ZigBee version integrates with an existing ZigBee-compatible hub — lower power consumption than WiFi and better suited to smart home setups where multiple sensors are already running on a ZigBee network. The right choice for anyone building out a more comprehensive smart home system who wants all their sensors on a single, efficient protocol rather than adding individual WiFi devices to the network. ZigBee sensors also tend to have longer battery life than WiFi equivalents, making them better suited to locations where battery access is inconvenient. 04Tuya Smart App — Remote Monitoring & AutomationsCompatible with the Tuya Smart and Smart Life apps, so it integrates with other Tuya-compatible devices you may already have — lights, locks, cameras, and more. Monitor open/close history, set automations (such as triggering a light when a door opens), and receive alerts from anywhere with a phone signal. The ecosystem compatibility that makes a single sensor more useful as part of a broader smart home setup — and means you don’t need a separate app for each device you add to your home.

The WiFi version works independently with just your home router and the Tuya app — the simpler, more accessible option for most households. Choose ZigBee if: you already have a ZigBee-compatible hub (such as a Tuya ZigBee gateway, Philips Hue bridge, or similar) and want to keep all your smart home devices on a single low-power network. ZigBee sensors typically use less battery power than WiFi equivalents and are better suited to large-scale smart home deployments. Both versions use the same Tuya Smart / Smart Life app for monitoring and alerts — the difference is in how they connect to your network, not in what they do. If you are unsure which version to choose, the WiFi version is the safer starting point — it requires no additional hardware and can be set up in minutes. You can always add ZigBee devices later if you expand your smart home setup. Installation Guide Download the Tuya Smart or Smart Life app on your phone and create an account if you don’t already have one. Insert batteries into the sensor (battery type specified in the included instructions). The sensor will power on automatically. Open the app and follow the ‘Add Device’ process — for WiFi, you’ll enter your network credentials; for ZigBee, you’ll need to add the sensor via your hub’s pairing mode first. Once paired, install the sensor on the door or window frame using the included adhesive tape or screws. The main body attaches to the fixed frame; the smaller magnet piece attaches to the moving door or window. Align them so they are within 10–15mm of each other when the door/window is closed. Test by opening and closing the door or window — you should receive a notification on your phone within a few seconds. Adjust the magnet position if the sensor does not register correctly. For best adhesion, clean the mounting surface with a dry cloth before applying the adhesive tape. Allow 24 hours for the adhesive to fully cure before the door or window is used heavily. Where to Use It Front and back doors: know immediately when anyone enters or leaves the property — useful for households with children, elderly relatives, or anyone who needs to monitor access. Ground floor windows: an alert whenever a window is opened unexpectedly, particularly useful at night or when the property is unoccupied. Garage or outbuilding doors: monitor access to secondary buildings without needing a separate security system. Medicine cabinets or storage: set an alert for any opening of a locked or sensitive cabinet — particularly useful in households with young children. Holiday properties or rentals: monitor check-in and check-out remotely via the app without needing to be on-site. Battery & Maintenance The Tuya app displays battery level for the sensor — check periodically and replace batteries before the level drops to a point where alerts may be missed. WiFi sensors typically use more battery power than ZigBee equivalents due to the higher power draw of WiFi connectivity. Expect more frequent battery replacements on the WiFi version in locations with high activity. If the sensor stops sending alerts, check the battery level first — low battery is the most common cause of sensor failure before checking connectivity or app settings. Clean the sensor body with a dry cloth if dust or moisture accumulates around the magnet or sensor gap. Do not use liquid cleaners on the sensor body.
