Connectivity Troubleshooting

Choose the Smart System connection path for an offline device, failed setup, or changed Wi-Fi network.

Choose the device and symptom before following any recovery steps. NS1, NS2, and NS3 connect directly to Wi-Fi; BLE and LoRa Sensors report through a Hub.

Offline Devices

Hub Offline

H3/H5/H6 Hubs: check power, internet access, Wi-Fi or Ethernet, and network diagnostics.

Wi-Fi Sensor Offline

NS1/NS2/NS3: check Sensor power and its direct Wi-Fi connection. These Sensors do not use a Hub.

Hub-Connected Sensor Offline

BLE/LoRa Sensors: check the Hub first, then Sensor power and Sensor-to-Hub signal.

If several Hub-connected Sensors go offline together, check their Hub first. If a Sensor is online but reports a disconnected probe or abnormal readings, use Measurement Troubleshooting.

Setup and Network Changes

Hub or Wi-Fi Sensor Setup Failed

Resolve discovery and network setup failures for H3/H5/H6 Hubs and NS1/NS2/NS3 Wi-Fi Sensors.

BLE or LoRa Sensor Setup Failed

Resolve QR-code, Bluetooth discovery, binding, and Hub communication problems for Hub-connected Sensors.

Wi-Fi/Router Changed

Reconnect your Hub or NS-series Wi-Fi Sensor after changing the router, Wi-Fi name, or password.
