Restart after shutdown by the OS itself (in the GUI)? about upsplus HOT 3 CLOSED

I did a new test.
Shut down the Pi from the Raspberry OS GUI.
I didn't touch anything.
After a while the UPS cut the power to the Pi.
After still more time, which seemed longer than 9-10 minutes, the Pi started up again by itself.

So, if you want to shut down the Pi and have it stay off, it's not going to work as it is, with the 'watchdog settings' in upsPlus.py (and therefore in the UPS registers).
How can this be solved? Taking the batteries out is not a very good solution.

1)You can rewrite the countdown, even if counting.
2)You are writing [Restart Countdown], of course it will restart, there is another register [Shutdown Countdown] that does not restart.
3)According to the test, the button is not responding during the countdown, we will plan to improve this feature.

Following your advice, I also tested watchdog timer functionality without restart (set 0x18 to >=120, 0x19 and 0x1A to 0). It works as promised. Thank you!
Restarting by pressing the button.
