I can control the sprinklers, but they only stay turned on for 5 minute intervals. If I throw the switch, they turn off on their own after 5 minutes. If I use the start_irrigation service, setting the duration for 15 minutes, they turn off after 5 minutes.
The Rainbird integration configuration defaults to 6 minutes when you manually turn on a station. You need to update the Rainbird configuration with a new default irrigation time. Attaching a screenshot.
