Currently there is a restart button, but it would be nice to have a shutdown button as well. Since raspberian and its SDCard are not verry happy with a hard shutdown, I like to perform a shutdown, but opening an ssh connection is not handy.
To be able to perform the shutdown from within the OSpi interface would be nice.
I’m assuming you want the sprinkler controller to turn after shutting down, correct? If so a shutdown button would require you to physically go power it back while a reboot would just fix the issue. Let me know if I’m misunderstanding.
I really don’t think this will ever be used by anyone and don’t think it will be incorporated into the app. Furthermore, I worry if accidentally pressed, the manual intervention required will not be ideal.
However, I do think if you need this there is an underlying issue that should be addressed. Why are you needing to shutdown?
