Hi  @Pablillogg 

Tapo camera requires time to boot up, this cannot be done in just a few seconds. If the camera (liveview screen) is only needed when there is movement or when the sensor is triggered, the privacy mode of the tapo camera might meet your needs.

Install Tapo sensor and camera->Create Smart Action (Automation) rule: when the sensor is triggerred, disable camera privacy mode.

Note: Not all Tapo cameras support Smart action, check here for all the supported models.

Or you can keep the camera ON all the time with motion detection and alarm features enabled for security purposes. Enable the privacy mode manually or use the Home mode/Away mode feature. 

As for disabling the automation rule, one-click disabling multiple rules is currently not supported. You can set an effective time for it to ensure that this function will not take effect outside the configured time.
