Smart Climate Monitoring

The Shelly BLU H&T ZB helps you understand and automate the conditions inside your home. Temperature and humidity readings can be used as triggers within your smart home system, allowing compatible devices to respond automatically as conditions change.

For example, you could turn on ventilation when bathroom humidity rises, activate a dehumidifier in a basement, control heating when temperatures fall, or run a fan when a room becomes too warm.

Popular Use Cases

Climate Control

Use current temperature and humidity readings to help automate compatible heating, ventilation and air conditioning systems and maintain a more comfortable indoor environment.

Help Prevent Mould and Mildew

Monitor humidity in bathrooms, laundries, basements and other moisture-prone areas. When humidity rises above your chosen threshold, your automation system can trigger compatible ventilation or dehumidification equipment.

Temperature and Humidity Alerts

Create notifications when environmental conditions move outside your preferred range. This can help identify excessive moisture, unusually low temperatures or sudden environmental changes.

Greenhouses and Plant Areas

Monitor greenhouse temperature and humidity and use the readings to control compatible watering, ventilation or climate-control equipment.

Environmental Monitoring

Sudden changes in temperature or humidity can provide useful information for home monitoring and automation scenarios involving leaks, excessive moisture or abnormal heat.

Automated Appliance Control

Use sensor readings to control compatible fans, humidifiers, dehumidifiers, heaters and other smart devices automatically.
