Hi! I understand your SOLARMAN Smart app was working fine but now it says it is registered to another plant. Let me help you clear this up.

Just to clarify a bit — did you recently change any device settings, have your inverter or logger replaced, or has someone else possibly added the same device to a different plant in the app? This info helps me narrow down the cause.

Generally, this message appears because the logger or device is still linked to another plant profile in the app or someone else’s account. Here's what you can do to troubleshoot step-by-step:

1. Check Existing Plant Devices:
Open the "Plant Details" in your app and look for any devices or loggers already listed. Confirm if your device is indeed registered elsewhere.

2. Unbind the Device from the Other Plant:
If you know the other plant or account where the device was previously added, ask to unbind or remove the logger from that plant. This lets you add it to your plant without conflict.

3. Re-Add the Device:
Once unbound, return to your SOLARMAN Smart app, go to "Device" > "Add a New Device" and enter the serial number (SN) of your logger or inverter again.

4. Contact Installer or SOLARMAN Support:
If you don’t know the other plant or can't unbind the device, your installer or SOLARMAN customer support can help deauthorize it from the previous plant for you. You can contact support via [email protected] for this process.

5. Reinstall or Update Your App:
Sometimes, small glitches cause incorrect error messages. Try logging out, uninstalling the app, then reinstalling and logging in again to refresh your account status.

With your Linux system and WebKit browser, your app should work normally after resolving the device binding issue.

Does this make sense so far? Were you able to check whether the device might still be registered in another plant? Let me know, and I can guide you through any step or help escalate if needed!
