I still think this is what you are looking for if you want to feed at 10, 1, 4 and 7.
Fallback OFF
OSC 060:000/000:20/119:40 Then ON
If Time 19:01 to 09:59 Then OFF
The 060:000 at the beginnng is telling the feeder to start the cycle at 60 minutes after midnight. You are asking the feeder to turn on every three hours, (180 minutes), so when you add up the total number of minutes and seconds in all three sections, they must equal 180 minutes.
60 minutes + 20 seconds + 119 minutes and 40 seconds = 180 minutes (3 hours)
060:000/ + 000:20/ +. 119:40 Then ON. = 180 minutes
If Time 19:01 to 09:59 Then OFF will prevent the feeder from turning on at the 1 AM, 4 AM, 7 AM, and 10 PM scheduled feeding.
Try it and see if it works.
