8. FAQs
(i) Failed to add the device and the product signal indicator light flashes slowly
The slow blinking signal indicates that the router is being connected. When the connection time exceeds 60 seconds,
the connection fails. Please check the WiFi password or retry pairing as there may have been a communication error
while performing the data transmission. Users also need to check the network status of the mobile phone or WiFi
router to troubleshoot any restrictions in allowing connection.
(ii) The App does not seem to control the shutters
- Check whether the WiFi password of the router has been changed.
- Check the indicator status of the device's signal. If it is flashing slow, it indicates that the App is disconnected from
the router. You will need to reconfigure the App.
- The IP address might have changed. Please restart your mobile and open the App again.
