Is the “Run Schedules” on the front page set to “ON”? It turns off every time you activate something in manual mode. I’ve been thinking that there should be a better use case here because I’ve been victim to forgetting to turn it back on but I haven’t come up with something that makes sense yet.
If it is “ON” and it’s still not working then there’s probably a bug somewhere, can you send me your settings and log file (settings is at /usr/local/etc/sprinklers_pi/settings. Log is at /var/log/sprinklers_pi.
