6. Operating Instructions

6.1 Reading the Display

The e-Ink display provides real-time information:

• Temperature: Current ambient temperature in Celsius or Fahrenheit.
• Humidity: Current relative humidity percentage.

• Battery Level: Indicator for remaining battery charge.
• Connectivity Status: Icons for Wi-Fi signal strength and Bluetooth status.

6.2 Smart Actions and Scenes

Integrate the Shelly H&T Gen3 with other Shelly devices within the Shelly Smart Control app to create intelligent automation scenes:

These automations can be configured through the Shelly Smart Control app, allowing for personalized environmental management.

7. Maintenance

7.1 Battery Replacement

When the battery indicator on the e-Ink display shows low power, replace the four 1.5V AA (LR) batteries. To do this, carefully open the battery compartment, remove the old batteries, and insert new ones, ensuring correct polarity. Note that the device does not recharge rechargeable batteries via its USB-C port.

7.2 Cleaning

To clean the device, gently wipe its surface with a soft, dry cloth. Do not use liquid cleaners, abrasive materials, or chemical solvents, as these can damage the device or its display.

8. Troubleshooting

• Device Not Connecting to Wi-Fi: Ensure the device is within range of your Wi-Fi router. Verify that the Wi-Fi network name (SSID) and password entered in the Shelly app are correct. If using battery power, the device may enter a low-power state; press the button located under the battery cover to wake it up for configuration changes or firmware updates.
• Inaccurate Readings: If temperature or humidity readings appear inaccurate, calibrate the sensor against a known reliable thermometer or hygrometer. Calibration options are available within the device settings in the Shelly Smart Control app.
• Display Issues: If the e-Ink display shows anomalies (e.g., partial display, flickering), try restarting the device by removing and reinserting the batteries, or by disconnecting and reconnecting the USB power. If the issue persists, contact Shelly support.
• Firmware Updates Not Applying: When operating on battery power, firmware updates or configuration changes may not apply immediately. Press the button under the battery cover to force the device to wake up and connect to the cloud, allowing it to receive pending updates.
