Connection problems
| Problem | Check |
|---|---|
| Hotspot is not listed | Wait 1-2 minutes after power-on, move closer, and look for a custom name if it was changed under Settings. |
| Hotspot password is rejected | Check the device label or use the password last saved under Settings > Wi-Fi setup hotspot. Passwords are case-sensitive. |
| Laptop shows No internet | This is normal on the setup hotspot. Continue to http://192.168.4.1. |
192.168.4.1 does not open | Reconnect to the gateway hotspot, type the full http:// address, and temporarily disable VPN or mobile data if it changes the route. |
| Cannot sign in | Use the administrator details created in the wizard or under Settings. If they are lost, a factory reset may be required. |
| Wi-Fi remains offline | Use 2.4 GHz Wi-Fi, re-enter the case-sensitive network name and password, and move the gateway closer to the router. |
| Cellular remains offline | Confirm the SIM is inserted and active, verify the APN, and enable cellular authentication only when required. |
MQTT and channel problems
| Problem | Check |
|---|---|
| Broker shows Not configured | Enter the required broker details and select Save MQTT settings. |
| Dropped increases | Restore the broker or internet connection. Readings can be discarded while the broker is unavailable. |
| Failed increases | Check credentials or certificates and confirm the account can publish to the configured topics. |
| TLS connection fails | Upload the correct root CA in PEM format, keep it below 4 KB, and use the broker's TLS port, commonly 8883. |
| Channel shows Disabled or Turned off | Enable the channel on its Sensors page and save the settings. |
| Firmware update was interrupted | Restore stable power and networking, sign in, and select Check for updates again. |
