Hi! I see you're having trouble connecting the Kohler Energy Management app on your iPhone with iOS 18.7. To help you better, could you let me know if the app fails to connect at all, or if it connects intermittently? Also, is your Kohler generator and controller powered on and connected to the home network with internet access?

Meanwhile, here are some straightforward steps to try:

1. Check Network Connection:
Ensure your iPhone is connected to a stable Wi-Fi or cellular network with good internet access.

2. Verify Generator Network Setup:
The generator itself must have a stable, hard-wired internet connection. Confirm that its controller is powered on and connected properly.

3. Open Necessary Ports:
Some users found that opening port 1024 on their router/firewall directed at the generator’s IP address helps the app reconnect. This may require accessing your router settings.

4. Reset Controller PIN:
Sometimes, the app requires a fresh controller PIN to authenticate. You can reset this on the generator’s display panel to get a new PIN and then enter it into the app.

5. Update Firmware and App:
Check for any updates for both the Kohler Energy Management app and your generator’s firmware to ensure compatibility.

If you’ve tried some of these already, please let me know which ones, and if you see any error messages in the app.

If none of these steps help, we can dig a bit deeper into your setup or contact Kohler customer service, who can assist with advanced troubleshooting. You can also find guidance in the Kohler Energy Management app Quick Start Guide available online.

Does this sound like a good place to start?
