The light is on x10 control. The feeder is it's own unit that runs on batteries..so there's no way to connect it to x10.
I see potential for "Forum Fun Design Contest"
Lets couple the feeder to X10 so X10 AHP can control the light!
1. Buy a second feeder so we can destroy the first.
Since the feeder runs on batteries it will be easily to couple it to a "Power Flash" module. This will be great fun, as it requires screw drivers, disassembly, and soldering!2. Solder two wires to the motor or solenoid that causes the feeder to dump its food.
3. Connect these wires to the Power Flash input.
4. Set the Power Flash to the desired HCUC.
Now everytime the feeder runs the Power Flash will send a HCUC "ON" command. When the motor stops, the HCUC "OFF" is sent. Use either command to fire macros and timers to control your lights. In my aquarium days I used similar setup to turn OFF the air pump and filters so the food would float on surface for a longer period of time.
