Watchdog Timer for UPS Hat – How does it work?

I’ve used SixfabPower class in the power_api to change the watchdog settings, per the API documentation, which appears to work. Can I just disable the power_agent service and have my script handle sending the watchdog signal?

Yes, you can. After disabling the agent service, you can use it by sending the watchdog_signal command. If the signal is not sent to the MCU within the watchdog_interval time, it does hard_reboot. Also, get_watchdog_status should return 1 when active and the watchdog_interval can be set using set_watchdog_interval function.

Thanks.
