Shutdown countdown in minutes?

[kralverde]

It appears the shutdown countdown is in minutes rather than seconds (as per https://wiki.52pi.com/index.php/EP-0136) in firmware v10

Is there a change log for changes like this?

Following this, is there a reason for values 1-9 to be disallowed in 0x18 now that the time is in minutes?

with a value of 60 at register 0x18, my UPS shuts down in one minute, as specified (with fw v10).

I will do more testing. Is there any possible reason for this behavior change? Is there a more in-depth register map than the one on 52pi.com?

In f/w v.10 countdown timer at 0x1A will count down and cut the power. Then the UPS waits 10 minutes before restoring power. I haven't seen this documented so one could easily think nothing is going to happen, but it will ... after 10 minutes. I don't know if the 10 minutes can be changed.
I write a python script to do that power cycle with a proper shutdown of the OS in those 60 seconds:
