I'm lost on what to do on this one and mabe someone here can help me come up with a way to control this or plumb it. I have a client who has a large koi pond, he has impact sprinklers with motion detectors that he manually turns on at night to protect the fish from raccoons and heron that comes in the morning. We're trying to figure a way to automate this. Now to set this automatically I could simply put a Hunter SVC and set it to come on at night and off in the morning. But the customer wants to be able to turn it on and off manually as they are often outside late at night and wants to turn it on during the day if needed if a neighbors cat comes in the yard. For this I could open the sensors and wire in a switch so that he can simply turn the sensors on and off by remote. But how can I control it to do both? and it needs to be a simple user friendly interface for him to use. So basically it can be programmed to turn on automatically at 10pm and off at 8am, but easily switched on during the day if needed and off at night if needed.
