Have the exact same problem, without the webinterface program’s dont run at all. If i leave the webpage open everything works. If i make a program that runs lets say for 10 minutes, and i keep the page open it starts… if i close the page after lets say 5 min’s the valve keeps open until i open the webpage again (15 min, 60, a day..)
I dont know the ins and outs but seems to me that the process that runs the schedule stops without the webinterface.
If i can help finding a solution please let me know…
