Thanks for reaching out. I understand that you are seeing a different number of connected devices in the Deco app compared to the TP-Link Network Discovery app, and some of your ESP devices do not appear in the Deco app even though they are connected and working.

This can happen for several reasons. Here are some steps you can follow to troubleshoot this issue:

1. If the Deco app shows zero online client devices:
• After opening the Deco app, please wait a few minutes to allow it to refresh the client list.
• Try rebooting your main Deco unit.
• Make sure your Deco app is updated to the latest version from Google Play or the App Store.

2. If only some devices are missing from the Deco app's client list but are working normally:
• Double-check that there are no other routers using the same Wi-Fi network name (SSID) as your Deco system, as this can cause confusion in device reporting.
• Ensure your client devices (such as your ESP modules) are set to obtain an IP address automatically (DHCP), not using a static IP.
• Reboot your entire Deco system to refresh the device list.

If you have tried these steps and the issue persists, please contact TP-Link support and let them know the results of your troubleshooting so far. This will help them assist you more efficiently.
