3 Steps to troubleshoot pairing issue:
1. Make sure the selected WiFi network is 2.4G private WiFi network, and is not a public WiFi network requiring credential login on a web portal like the ones at airport.
2. Verify the entered WiFi password is right.
3. Move your Sense-U device close to your WiFi router and make sure you are able to connect to internet.
4. If you are using a WiFi 6 router with single network ID (SSID), make sure to unselect "SMART CONNECT" from your router's web interface or app, and then choose the 2G SSID to pair:
(e.g: TP-Link Tether App)
Tips: Where to find Smart Connect for typical routers:
