Hi
I have Witty Pi 4. I am having some difficulty using the script to set a schedule on it. When ever I run the wittypi.sh script then select the option to chose a schedule I get the same scheduled shutdown and start up. It does not seem to matter what is in the .wpi schedule file I send I always get the same response. Manually changing the schedule time using the wittyPi.sh script does appear to work.
I have attached the log file so you can see. It does appear to write the data to the schedule.wpi file successfully but not then use this to schedule start up correctly.
Section of log file is copied below.

An example of the schedule file is below.
# Turn on Raspberry Pi for 1 hour, in every 2 days
BEGIN 2022-06-01 00:09:55
END 2035-07-31 23:59:59
ON H1 M10 # keep ON state for 1 hour
OFF H22 M50 # keep OFF state for 1 day and 23 hours

The behavior you mentioned is expected. This is called "shifting ON state", please read page 19 on the user manual to understand how it works.
Although the comments in your schedule script says it turns on Pi for 1 hour in every 2 days, the actual code in that schedule script is actually turning on Pi for 1 hour 10 minutes within 24 hours.
Once you defined the BEGIN time, and the durations for ON and OFF states, the whole planning has been defined, as below:
......
OFF -> 2024-08-08 01:19:55
ON -> 2024-08-09 00:09:55
OFF -> 2024-08-09 01:19:55
ON -> 2024-08-10 00:09:55
......
When you run the schedule script, the software knows your Pi is currently ON. If at the current moment your Pi is suppose to be OFF, the software will shift to next avaialble ON state and schedule the shutdown and startup accordingly.
In your case, for both times it shifts to ON state starting from "2024-08-09 00:09:55", and hence the incoming shutdown and startups are the same. This will change when the current time exceeds 2024-08-09 01:19:55.
