Hi there! I understand you're having trouble controlling your B-hyve watering system via the app, and you have a sprinkler stuck on. Let's work together to resolve this.

First, could you let me know if you can see your device listed in the app? Also, are you connected to a stable Wi-Fi network? This information will help me guide you better.

In the meantime, here are a few common troubleshooting steps that you can try:

1. Check Internet Connection: Make sure your smartphone is connected to the internet, as the app requires a stable connection to communicate with your B-hyve system.

2. Restart the App: Close the B-hyve app completely and then reopen it. Sometimes a simple restart can resolve issues.

3. Reboot the B-hyve Device: If the sprinkler is still stuck on, try rebooting the B-hyve device. You can do this by unplugging it from the power source for about 10 seconds and then plugging it back in. This can help with connectivity issues.

4. Check for Rain Delay: Sometimes the system can get stuck in a rain delay state. If you have the option, toggle the rain delay feature a few times in the app to see if that resolves the issue.

Let me know how these steps go, and if the issue persists, we can dig a little deeper!
