I have some Tapo Cameras and many Kasa devices. I use different TP-link accounts for Tapo devices and Kasa devices.  I want the Tapo Camera to turn on a light controlled by a Kasa switch when motion is detected. I think this can be done using 'linking Tapo and Kasa'. I logged into my Tapo account and selected 'link Tapo with Kasa'. But it came back with no available devices. This is expected as my Kasa devices are under another TP-link account. To fix this, I need to move Tapo camera and Kasa devices to the same TP-link account. Google search results say that I have to reset the devices to move it to another account. I need some help on this

1. There is no change in the wireless connection for Tapo and Kasa devices (same SSID and connection pin). Is a reset still necessary to move the device to a different account?

2. The Tapo cameras and some Kasa devices are hard to reach physically (high above ground or behind cabinets). Is the required reset a hard reset using the physical reset button on the device or a soft reset that can be done using the Kasa App or Tapo App?

3. In order to use Tapo device to trigger Kasa devices, is it a must to move Kasa devices to the Tapo account?

4. This is a side question. My current TP-link accounts are registered with Gmail IDs. I am planning a vacation to China, where Gmail is not accessible. Will that impact my ability to monitor or control my Tapo or Kasa devices from China? If yes, I may as well create a new TP-link account using Outlook Id (Microsoft email is still available in China) and move everything there.
