As mentioned a IP switch for power is the option for powering equipment. Always on option in Bios for computer. Port forwarding options and setup to your router.
Then for redundancy and protection:
- Cloud sensor system.
- Roof software to monitor the cloud sensor software.
- Command programme to monitor to orchestrate everything for shut down in weather abort situation. There are some good ones out there. CCDAP, ACP and I am sure that SGP does the same.
Good luck with it all. It takes a bit of persistence but you will get it all working with some time.
