Nous E9 Tuya Zigbee household combustible gas detector

The NOUS E9 is a Zigbee 3.0-based household flammable gas detector that continuously monitors the air 24/7 for gasoline, methane, propane, and other flammable gases. It provides immediate alerts via sound and light when gas concentrations reach dangerous levels, and also sends automatic notifications through the mobile app.

The device is CE and RoHS certified, made of fire-resistant plastic, and designed for a 5-year lifespan. Thanks to its Plug & Play operation, all you need is a compatible Zigbee hub (e.g. NOUS E1/E7 or any Tuya-based gateway) for quick installation.

This is a premium-grade, reliable safety device that supports remote notifications and integration with voice assistants (Alexa, Google Assistant). It also supports community-driven integration with Home Assistant via Zigbee2MQTT.
