When you receive the 'Wi-Fi Connection' error message while pairing, please check the following:

A: Check permissions, navigate to your phone settings, locate the KNECT Pro app, and ensure that all necessary permissions are approved. If the problem persists, consider uninstalling and reinstalling the app, agreeing to all permissions during the installation process.

B: Forget the SENSIT network in phone's Wi-Fi settings, go to your phone settings, access the Wi-Fi section, and locate the SENSIT network. Choose the "Forget" option to remove it from your saved networks.

C: Check your home network credentials.

D: Ensure that your phone is connected to the SENSiT network when attempting to pair. You may observe a "no internet" notification, which is expected and correct during this process.

This product is designed to assist with monitoring and managing tank levels by providing indicative level data. It does not actively prevent run-outs or overfills. The accuracy of the reported data is approximately ±5%, depending entirely on the accuracy and completeness of the setup information and parameters provided by the customer.

It remains the customer’s full responsibility to ensure that correct configuration details are supplied and that data is reviewed regularly. The manufacturer and supplier accept no liability for run-outs or overfills if data is not sent, received, or displayed due to network issues, server downtime, customer internet failures, or other transmission disruptions. This product supports level management but is not a fail-safe device or guaranteed prevention system.
