Not sure if this is the right place for this, of it should be device hacking, but he is my goal.
I have some very aggressive pest, and I al 100% not going to use anything lethal. So I want to use a device like the pest sprinkler to shot them with water. The issue I have is that it is in my driveway and I don't want my wife to get sprayed every time she comes home. I am thinking that it should be a simple act of adding a schedule and a mech to remotely turn off.
I am thinking as these devices are low voltage (4 AA batteries), I should be able to cut into the wiring and add my own device to add the functionality I want.
Please feel free to suggest where i should start.
