Hi! I’m sorry to hear that your device in the Ambient Weather Network app appears and then disappears right away on your phone. Just to get a clearer picture, could you tell me:

- What kind of phone and operating system version you are using?
- Has the app been updated recently before this issue started?
- Is the device properly connected to the internet and powered on?
- Have you tried logging out and back into your Ambient Weather account within the app?

Meanwhile, I can offer a step-by-step troubleshooting approach to try:

1. Restart the app and phone: Close the app completely (swipe it away from recent apps) and restart your phone. Sometimes this refreshes connections.

2. Check internet connection: Ensure your phone has a stable Wi-Fi or data connection, as intermittent connectivity could cause the device to momentarily appear then disappear.

3. Logout and login: Within the app, sign out of your Ambient Weather Network account and sign back in. This can refresh the data sync with the device.

4. Check device status on AmbientWeather.net: Log in to your account on the Ambient Weather website (ambientweather.net) and verify if your device is still listed and reporting data properly there.

5. Update or reinstall the app: If you haven’t already, check for any app updates. If the issue persists, uninstall and reinstall the app to clear any corrupted files.

6. Reset your weather station: Sometimes sensors stop reporting to the console and the app1. Try resetting or power cycling your weather station device.

7. Verify device listing: On some cases shared by users online, going to the “My Devices” section on the app or website and manually clicking on the missing device has brought it back to normal view2.

If after these the problem continues, please let me know exactly which phone and app version you have, and I can help you dig deeper. Would you like me to guide you through any of these steps right now?

Are you satisfied with the solution I provided so far?
