Wireless Indoor Smoke Detector Hurtel NOUS-E8 with 85 dB Siren, TUYA ZigBee and MQTT Support

Hurtel NOUS-E8 is a wireless indoor smoke detector designed for early detection of smoke in homes and small commercial spaces. The device includes an integrated 85 dB siren to provide an immediate audible alarm on site. It supports TUYA ZigBee and MQTT protocols, enabling integration with a wide range of smart home and automation systems that accept ZigBee or MQTT devices. The compact form factor allows installation on ceilings or walls in living rooms, hallways, kitchens and offices.

Advantages

The detector combines optical smoke sensing with a built-in high-volume siren to deliver local alerts while also offering network connectivity for remote monitoring and automation. Support for TUYA ZigBee and MQTT allows flexible integration into existing smart home ecosystems and third-party automation platforms. Wireless operation simplifies installation without the need for hardwiring, and the compact design minimizes visual impact while remaining accessible for maintenance.

• Residential rooms: living rooms, bedrooms and kitchens
• Hallways and corridors in apartments or houses
• Small offices and commercial premises
• Integration into smart home systems for automated alerts and actions

Key specifications

• Detection type: optical/photocell smoke sensor
• Alarm output: integrated siren with up to 85 dB sound level
• Connectivity: ZigBee (TUYA compatible) and MQTT support for network integration
• Power: battery-powered wireless operation (user-replaceable battery)
• Mounting: ceiling or wall installation with included mounting hardware
• Operating environment: indoor use, typical residential and commercial indoor temperature and humidity ranges

How to use

Choose a location on the ceiling or high on a wall away from ventilation outlets and cooking appliances to minimize false alarms. Install the detector using the supplied mounting plate and screws, insert the battery, and follow the device pairing procedure to add it to a TUYA ZigBee or MQTT-enabled hub or gateway. After successful pairing, verify the alarm and communication status through the connected hub or app and perform a test to ensure the 85 dB siren sounds correctly.

Usage recommendations

Test the detector regularly according to local safety recommendations and replace batteries promptly when indicated. Avoid installing the unit too close to kitchens or bathrooms where steam, cooking fumes or strong drafts may cause nuisance alarms; instead place them in adjacent spaces or corridors. When integrated with a smart hub, configure notifications and automated responses (lighting, HVAC shutdown, notifications) to suit occupancy patterns and safety procedures.
