Precise Climate Monitoring
The Shelly H&T Gen3 wakes up every minute to take accurate temperature and humidity measurements, updating the e-paper display when there's a 0.2°C temperature change or 3% humidity difference. It reports data to the Shelly Cloud based on customisable thresholds (default: 0.5°C or 5%), ensuring you're always informed without draining battery life. With an NTP-synchronised real-time clock, you'll also always know the current time alongside your climate data.
Smart Home Integration & Automation
Take control of your indoor climate with powerful automation scenarios. Integrate the Shelly H&T Gen3 with other Shelly devices like the Plus 1 relay to automatically turn on bathroom fans when humidity spikes, or trigger heating in rooms without thermostats. Use webhooks, MQTT, and scripting for advanced custom automations, or simply control everything through the free Shelly Smart Control app on iOS or Android. Voice control via Google Home or Alexa makes it easy to check conditions hands-free.
Flexible Power & Installation
Choose the power option that suits your needs. Install the Shelly H&T Gen3 anywhere with 4 × 1.5V AA batteries (not included) for up to 12 months of operation, or power it continuously via the USB Type-C port for more frequent updates and always-on monitoring. The compact design (70 × 70 × 26mm without stand) and included stand make placement effortless on shelves, desks, or wall-mounted surfaces.
Built for Australian Homes
Whether you're monitoring a baby's nursery, controlling bathroom humidity, tracking wine cellar conditions, or ensuring your home office stays comfortable year-round, the Shelly H&T Gen3 delivers reliable performance in residential, light commercial, and educational settings. Its operational range of 0°C to 40°C and 30% to 70% RH covers typical Australian indoor environments with ease.
