Troubleshooting

Symptom	What to do
I did not receive the activation PIN	Check spam and junk folders; use Resend activation PIN — the new code invalidates the previous one. Confirm the registration e-mail is correct
Equipment shows offline, but it is on	The status considers the last minute. Pull the list to refresh; check the equipment's Wi-Fi LED and the Diagnostics screen (Chapter 13)
Equipment offline after changing router or moving house	The network stored in the equipment has changed. Tap the card and use the Change network action — the wizard reconfigures the Wi-Fi
The setup wizard fails at the final step	It is almost always the Wi-Fi password. Try again checking the password, and confirm the network is 2.4 GHz
I can't calibrate / configure Wi-Fi / reset from the app	These actions require the phone on the same network as the equipment — it is protection, not a defect. Connect to your home Wi-Fi and try again
Push does not arrive	Check the app's notification permissions in the phone's system settings, and the equipment's channel in Notification Preferences
Telegram does not arrive	Confirm the link in your profile and the Telegram channel on the desired equipment. Redo the `/start` with the account's exact e-mail
Sharing says the user was not found	The guest needs to create their Aquarino account first, with the same e-mail you are entering
The app asks for a firmware update on the equipment	The equipment is below the supported minimum. Update it through the Local Manager and come back
The app asks for my biometrics all the time	It is the biometric lock interval in your profile — set a longer interval, or turn it off

If it persists, export the session logs on the Diagnostics screen and send them to support along with a description of the problem.
