Messed up

Today, it was supposed to rain. So, I put the system on standby. Two hours later, I got a notification that the watering started and then ended according to the schedule. But it was supposed to be off!!! What is going on?!? Worst update since I purchased the system in May 2015!!! Please fix ASAP.
