5.2. Smart Alerts and Notifications
The INKBIRD App allows you to set custom high/low temperature and humidity alert ranges for each sensor. If the detected values exceed these preset ranges, the app will send instant notifications to your smartphone, ensuring you are always aware of critical changes.
- Høj/lav temperatur alarm: Receive alerts if temperature goes outside your set limits.
- High/Low Humidity Alarm: Receive alerts if humidity goes outside your set limits.
- Lavt batteri påmindelse: Get notified when sensor batteries are running low.
- Offline Reminder: Be alerted if a sensor loses connection to the gateway.

6. Vedligeholdelse
To ensure optimal performance and longevity of your INKBIRD ITH-20R-O system, follow these maintenance guidelines:
- Udskiftning af batteri: Replace the 2x AAA 1.5V batteries in the sensors when a low battery notification is received. Use high-quality alkaline batteries for best performance.
- Rensning: Wipe the sensors and gateway with a soft, dry cloth. Do not use abrasive cleaners or immerse the devices in water.
- Placering: While the sensors are rainproof, avoid prolonged exposure to direct sunlight or extreme weather conditions to prevent damage and ensure accurate readings. Place sensors in locations that provide representative readings for the area you wish to monitor.
- Firmwareopdateringer: Regularly check the INKBIRD App for any available firmware updates for the gateway or sensors. Updates can improve performance and add new features.
7. Fejlfinding
If you encounter issues with your INKBIRD ITH-20R-O system, refer to the following common problems and solutions:
- Sensor not connecting to Gateway:
- Ensure the sensor batteries are correctly installed and not depleted.
- Make sure the sensor is within the 300ft/91m transmission range of the gateway.
- Verify the gateway is powered on and connected to your 2.4GHz Wi-Fi network.
- Try re-pairing the sensor by following the 'Sensor Setup' steps (Section 4.3).
- Gateway not connecting to Wi-Fi:
- Confirm your Wi-Fi network is 2.4GHz. The gateway does not support 5GHz networks.
- Kontrollér, at din Wi-Fi-adgangskode er nøjagtig.
- Sørg for, at gatewayen er inden for rækkevidde af din Wi-Fi-router.
- Restart your Wi-Fi router and the gateway, then attempt to reconnect.
- Upræcise læsninger:
- Ensure sensors are not placed near heat sources (e.g., direct sunlight, appliances) or strong drafts that could affect readings.
- Allow sensors to stabilize for 15-30 minutes after placement or battery change.
- Check for any physical damage to the sensor.
- Ingen app-notifikationer:
- Verify that notifications are enabled for the INKBIRD App in your phone's settings.
- Check that alert thresholds are correctly set within the INKBIRD App.
- Sørg for, at din telefon har en aktiv internetforbindelse.
8. Brugertips
Here are some tips to enhance your experience with the INKBIRD ITH-20R-O system:
- Optimal placering: For best results, place sensors in central locations within the area you want to monitor, away from direct sunlight, vents, or extreme temperature fluctuations. For example, in a wine cellar, place it near the center of the room, not directly next to a wall or the door.
- Udvidelsesmuligheder: Remember that the WiFi Gateway can support up to 10 sensors. If you need to monitor more areas, additional ITH-20R-O sensors can be purchased separately and easily added to your existing system.
- Dataanalyse: Utilize the data export feature to track long-term trends in temperature and humidity. This can be particularly useful for monitoring conditions in greenhouses, reptile terrariums, or storage areas where stable environments are crucial.
