The DIYANI ZG-227Z is a compact Zigbee 3.0 sensor that measures temperature and humidity in real time and reports it to your smart home hub (a Zigbee coordinator that controls Zigbee devices). Ideal for monitoring the climate in living rooms, bedrooms, basements, or offices, and for controlling heaters, fans, or dehumidifiers based on accurate data. This sensor works completely locally via Zigbee 3.0 (a protocol for wireless smart home devices), without cloud dependency, and automatically reports the current values to your hub every 5 minutes. What can this sensor do? The ZG-227Z is a battery-powered sensor that measures temperature (from -10°C to +50°C) and humidity (0%–95% RH) with high accuracy (±0.3°C for temperature, ±3% for humidity). The device uses Zigbee 3.0 to communicate wirelessly with compatible hubs and platforms like Home Assistant, allowing you to monitor the climate and create automations (for example, turning on a fan if the humidity rises above 70%). Connectivity and protocols Protocol: Zigbee 3.0 (requires a Zigbee hub such as Home Assistant with ZHA, Zigbee2MQTT, Homey Pro, or similar coordinators) Communication: Wireless, mesh network (the sensor does not extend the Zigbee network, it only works as an end device) Reporting interval: Temperature, humidity and battery status are automatically reported every 5 minutes Range: Up to approx. 30 meters of open space between sensor and hub (depending on obstacles and other Zigbee devices in the network) Platform compatibility Home Assistant: Excellent support via ZHA (native Zigbee integration in HA) and Zigbee2MQTT; reports entities for temperature, humidity, and battery percentage Other hubs: Compatible with Tuya Smart/Smart Life app (via Tuya Zigbee gateway), Homey Pro, and other Zigbee 3.0 certified hubs Voice Assistants: Works with Alexa and Google Assistant via supported hubs (e.g., "Alexa, what is the humidity in the living room?") Matter: No native Matter support; only via Zigbee 3.0 Nutrition and energy Battery: CR2450 (3V, included with purchase) Battery life: Approximately 1 year at normal reporting intervals (every 5 minutes), depending on ambient temperature and signal strength Battery Status: Battery percentage is reported in ZHA and Zigbee2MQTT for proactive low power alerts Functional properties and sensor properties Temperature range: -10 °C to +55 °C (suitable for indoor and unheated areas) Temperature accuracy: ±0.3 °C (high precision for reliable climate automation) Temperature resolution: 0.1 °C (fine measurements, ideal for heating controls) Humidity range: 0%–99% RH (relative humidity, no condensation) Humidity accuracy: ±3% RH (sufficiently accurate for mold prevention and comfort monitoring) Humidity resolution: 1% RH Sensor type: Digital temperature and humidity sensor Response time: Automatic update every 5 minutes; sensor responds to climate changes within seconds, but only reports at the next interval Automation and smart home integration Automations in Home Assistant: Build scenes and automations based on temperature and humidity thresholds (e.g. turn on dehumidifier at >70% RH, adjust heating at ±0.6 °C, humidity >±6%) Network latency: Zigbee 3.0 offers low latency (typically
