Hi there! I understand you’re having trouble logging into the Ecowitt app on your iPhone running iOS 26.0.1, but you can access the website with the same login just fine. Let’s work through this together.

First, can you tell me if you see any specific error messages when trying to log in to the app? Also, have you tried any steps already, like restarting the app or your phone?

Meanwhile, here’s a step-by-step approach we can start with:

1. Restart the Ecowitt app: Double press the Home button (or swipe up from the bottom if using Face ID) to see app previews, then swipe Ecowitt off the screen to close it. Open it again and try logging in.

2. Restart your iPhone: Sometimes a fresh reboot clears temporary glitches related to app login.

3. Check for Ecowitt app updates: Go to the App Store and see if there’s an update available for the app. Sometimes developers release fixes for login issues especially after iOS updates.

4. Clear app cache/data: Although iOS apps don’t have a “clear cache” option directly, you can try uninstalling Ecowitt and reinstalling it to reset its stored data.

5. Check network connection: Make sure you have stable internet (Wi-Fi or cellular). Sometimes flaky connections cause login timeouts.

6. Verify app permissions: Go to Settings > Ecowitt and ensure the app has the necessary permissions (like cellular data) enabled.

7. Try logging in with the same credentials on a different device or iOS version (if available) to confirm it’s not account-related.

There are reports that some users experience timeouts or login glitches on iOS 26.0.1 specifically with Ecowitt app1. If the above steps don’t resolve it, the problem might be temporary or related to app compatibility with this iOS version.

If after reinstalling and trying again the login still fails, I recommend contacting Ecowitt support to check if this is a known issue pending a fix in an app update.

Please let me know how these steps work out or if you encounter any error messages during login. I’m here to help! Are you satisfied with the solution I provided so far?
