Answering your final question, you are correct, the password is the interval program password that defaults to “opendoor”.
To touch on the interval again, it doesn’t matter what it is so long it’s longer than any feasible time within your start and end time duration. For example, if you have a start of 2:00AM and an end of 5:00AM you can put the interval to 3 hours (180 minutes) and be confident the program won’t run more than once (assuming you have a station run time of at least 1 minute, in this example). The interval is the amount of minutes to wait before running the program again within the confines of the start and end time.
The ignore password box not updating might be a bug. I will look into this, thanks!
