Watering schedule is different on the web (safari) and mobile (android). On the mobile I can set enable “on or off”. If I turn it off, it “disappears” from the web schedule display, but on the android it still shows with a duration of X. However, because it is not enabled it will not run.
However if I have turned it off (on the android) there is no way I have found to turn it on via the web and it does not even show up, unless I log out and log back in.
So I suggest on the Android, you leave it just like it is, except you add a filed saying if it is on or off. And on the web, you display it, just like you do on the android, but you also add an enabled “on/off” tag
