Hi,
Adding a hub to the system won't make the response time faster since neither the camera nor the bulb will connect to the hub.
In this case, please check if your camera and the bulb obtain a strong signal strength from your router, and you can move them close to your router and check if the smart action response time will be faster.
Best Regards

Hi,
Please help confirm the following information for the reported case for further analysis.
1. Please ensure the notification feature on the Tapo C520WS is enabled, and when the camera detects a motion, please record the time, date, and time zone when receiving the notification.
You can go to the Tapo app>Home tab>tap the Bell icon at the top right corner>click on your camera to see when you receive the notification.
2. On the Smart tab>History page, please find the corresponding smart action entry execution log and send me a picture of it.
3. On the camera and bulb's Device Settings>Device Info page, if you tap the Wi-Fi icon, you can see the signal strength value, please help confirm the detailed value.
Best Regards
