Flex scheduling jacked up?


#1

Ran my unit for the first time this year last night. Schedule said it would run from 7:53 to like midnight. Woke up someone after midnight and it was still running. Very comforting when I looked at the to do and it probably had another hour + left. Also there were zones that were literally set to have 1 min runtimes with a random soak cycle that wasn’t needed.

I like the much needed app updates but WTF is going on with my schedule?

@Hooper I checked your schedule run and looks like the total duration is 21352 seconds (5.93 hours). Starting at sunset (7:51pm) it will not finish until ~ 1:45 am. Here is the breakdown of the run in seconds.

zone # irrigation type duration
1 IRRIGATE 1500
2 IRRIGATE 1500
3 IRRIGATE 480
4 IRRIGATE 660
5 IRRIGATE 660
6 IRRIGATE 1020
7 IRRIGATE 780
8 IRRIGATE 780
9 IRRIGATE 780
10 IRRIGATE 780
1 IRRIGATE 1500
2 IRRIGATE 1500
3 IRRIGATE 480
4 IRRIGATE 660
5 IRRIGATE 660
6 IRRIGATE 1020
7 IRRIGATE 780
8 IRRIGATE 780
9 IRRIGATE 780
10 IRRIGATE 780
1 IRRIGATE 10
2 IRRIGATE 10
3 IRRIGATE 205
4 IRRIGATE 660
5 IRRIGATE 660
6 IRRIGATE 87
7 IRRIGATE 207
8 IRRIGATE 252
9 IRRIGATE 252
10 IRRIGATE 442
5 SOAK 433
4 IRRIGATE 127
5 IRRIGATE 127

Since your third cycle is shorter than the first 2, zone 5 requires an extra soak period in the 4th cycle. In V3 we always irrigate for maximum allowed duration first and then the remainder, versus V2’s even division. This is more efficient for most long irrigations. Please let me know if you have more questions.

Thanks for explaining the rationale, but I guess I still have issues with this. How is a 10 second irrigation useful? Honestly anything less than a minute the water won’t even make it out to the heads. Also in the app the duration is totally not consistent with what you have outlined here. In the app it will say for example 7:53 -10:26 which does not jive with actual runtime.

Look I am just coming at this this from a totally unsophisticated users perspective and it doesn’t make sense to me.

@Hooper We will be improving smart cycle calculations and soon short irrigation cycles will no longer be an issue. The mismatch in the duration could be due to recalculation of the calendar within an hour of start time. In flex daily schedules we dynamically add zones if the moisture level drops below zero. If forecasted/observed values have changed since your last calendar check, the schedule will adjust accordingly. So duration could change right before start. Hopefully this makes it more clear.
