Hi,
1. You can refer to the link below to set up the Smart Action feature to make the Tapo C310 work with Hub H100 for alarm.
How to create Smart Action (automation or a shortcut) of my Tapo devices?
Trigger: when the camera detects motion, person, area intrusion, etc.
Action: Ring H100
2. It's unable to manage the camera remotely using the Tapo app without a cloud service. However, the Tapo C310 supports RTSP/ONVIF and you can watch the camera remotely via RTSP/ONVIF.
How to view Tapo camera on PC/NAS/NVR through RTSP/Onvif Protocol?
Note: If you want to view the live stream of the Tapo camera with a third-party app remotely, you will need to open port 554 for the camera on your host router first. Please enable the TCP forwarding for port 554.
Best Regards
