Best Nous Zigbee Devices in 2026
Nous is one of the most underrated Zigbee brands available today. It offers solid build quality, confirmed Zigbee2MQTT and ZHA compatibility, and pricing well below the big names. This article covers the best Nous Zigbee devices by category. That includes smart plugs, sensors, and safety devices. If you are running Home Assistant, every Nous Zigbee device listed here works locally with no cloud required.
Key Takeaways
- The Nous A1Z is the best overall Nous Zigbee device for most Home Assistant users.
- All devices listed here work via Zigbee2MQTT and ZHA with no Nous gateway required.
- The Nous E6 is the best sensor pick for users who want at-a-glance climate readings.
- The Nous E9 gas detector doubles as a permanent Zigbee router because it is mains-powered.
- No Nous-specific hub is needed for Home Assistant. Any universal coordinator works.
What Is the Nous Zigbee Lineup?
Nous is a European smart home brand with a complete Zigbee 3.0 ecosystem. Their Nous Zigbee devices are built for energy efficiency and simplicity. Many include built-in energy monitoring to help you track power consumption over time.
There are two ways to use Nous hardware:
The Cloud Path: Use a Nous E1 (wireless) or E7 (LAN) gateway paired with the Nous Smart Home or Tuya Smart apps.
The Local Path: Connect directly to Home Assistant via Zigbee2MQTT or ZHA. All communication stays on your local network with no cloud dependency.
For Home Assistant users, the local path is the right choice. Every device in this article has been confirmed as supported in Zigbee2MQTT.

What Are the Best Nous Zigbee Devices in 2026?
⭐ Nous A1Z — Best Overall Nous Zigbee Device
The Nous A1Z is the standout pick across the entire Nous Zigbee lineup. It is a compact 16A Zigbee 3.0 smart plug that handles up to 3680W. That covers most household appliances without any issues. Beyond switching, it tracks real-time energy data including voltage, current, and wattage. It also has a physical child lock built in.
I have been running several A1Z units across my setup for a while now. What I appreciate most is how reliably they pair and stay connected. Every A1Z also acts as a Zigbee router. Each plug you add extends coverage for battery-powered devices nearby. At this price point, that mesh-strengthening behaviour is genuinely useful.
Home Assistant Integration
The A1Z pairs cleanly with Zigbee2MQTT (Zigbee ID: TS011F) and ZHA. It exposes detailed entities including power, energy, current, voltage, and power-outage memory. No Nous gateway or cloud account is required.

Best Nous Zigbee Safety Devices
Nous safety Zigbee devices include gas detection and smoke sensing, both integrated with Home Assistant locally.
Nous E9 — Best Gas Detector
The Nous E9 is the most unique device in the Nous lineup. It is a mains-powered (100-240V) combustible gas detector for methane detection. Because it runs on mains power, it also functions as a permanent Zigbee router. Every E9 you install improves safety and strengthens your Zigbee mesh at the same time.
The device requires a three-minute warm-up period after power-on before it begins active detection.
Home Assistant Integration
Supported via Zigbee2MQTT. Exposes gas detection, warming-up status, and fault indicator entities. Note that as of late 2025, some users reported inconsistency in the data flow from Zigbee2MQTT to Home Assistant. Verify on your build before relying on it for critical safety automations.
Key Features
- Mains-powered (100-240V) with thin mains lead
- Combustible gas (methane) detection
- Acts as a permanent Zigbee router
- Zigbee 3.0
- 3-minute warm-up after power-on
- Supported via Zigbee2MQTT
Pros
- Doubles as a Zigbee router, strengthening your mesh
- No battery to replace
- Permanent, always-on detection
Cons
- Requires mains power and proximity to an outlet
- Some users have reported ZHA-to-HA data flow inconsistency (late 2025)
- Not battery-portable
Best For: Kitchens or utility rooms where a mains-powered safety device also helps extend the Zigbee mesh.
Nous E8 — Smoke Sensor
The Nous E8 is a dedicated Zigbee 3.0 smoke detector. Pairing it with Home Assistant opens up local safety automations. You can trigger all lights to turn on, send push notifications, or activate a siren when smoke is detected.
Home Assistant Integration
Supported via Zigbee2MQTT. ZHA support to be confirmed on your specific build.
Key Features
- Zigbee 3.0 smoke detection
- Supported via Zigbee2MQTT
- Enables local safety automations in Home Assistant
Pros
- Enables cloud-free smoke alerts through Home Assistant

How to Connect Nous Zigbee Devices to Home Assistant
All Nous Zigbee devices pair using the same method regardless of device type.
Method 1: Zigbee2MQTT (Recommended)
Method 2: ZHA
Ishara Fernando
A Nous-specific gateway is not required. Any universal Zigbee coordinator works. I personally use the SMLIGHT SLZB-06. I cover it alongside other strong options in our best Zigbee gateway for Home Assistant guide.
Conclusion
Nous offers one of the most complete and affordable Zigbee 3.0 ecosystems for Home Assistant users in 2026. Whether you are just getting started with Nous Zigbee or expanding an existing setup, there is a device for every part of the home. The A1Z is the standout device for everyday use. It combines energy monitoring, mesh extension, and local control in a compact plug. For sensors, the E6 is the pick for visible readings. The E5 covers discreet long-life monitoring.
The E9 gas detector is worth a special mention. It improves safety and strengthens your Zigbee mesh at the same time, all from mains power.
