FEATURES

• Zigbee 3.0 Home Assistant Integration: Natively compatible with Home Assistant via Zigbee coordinators (e.g., ZHA, Zigbee2MQTT) for reliable, low-latency performance. Also works with Echo (4th Gen), Echo Plus (1st/2nd Gen), Echo Studio, Eero 6/Pro 6, SmartThings (2015/2018), Aeotec, Hubitat, Homey Bridge/Pro, and ThirdReality Hub. (Zigbee coordinator required, sold separately.)

Ideal for indoor use in living rooms, greenhouses, or basements, with instant visibility of environmental conditions.  
• Powerful Home Assistant Automations: Create custom automations in Home Assistant to control your smart home—e.g., turn on a smart plug for a heater when the temperature drops below 18℃, activate a humidifier when humidity falls below 40%, or send notifications if conditions exceed your thresholds. Combine with Zigbee-compatible devices like Sonoff or IKEA Tradfri for seamless climate control.
