Watering Plan, Rain Drops and Delay

in SW and Settings

Hi,

I have three valves which I need to run seperatly due to the water pressure.

I used one Schema P2 and defined to run at 8:00 for 10 minutes.

Then I assigned the P2 to all three valves.

First valve is using a 0 second delay.

Second valve is using a 600 second delay.

Third valve is using a 1200 second delay.

When there is exactly one rain drop, then this works flawlessly.

Valve 1 starts at 8:00 till 8:10

Valve 2 starts at 8:10 (basically it starts at 8:00 with 600 second delay)

Valve 3 starts at 8:20 (basically it starts at 8:00 with 1200 second delay)

So far so good.

Now I increased the rain drops from 1 to 3.

My assumption was, that also the dealy would increase, however that's not what I see.

Valve 1 starts at 8:00 till 8:30 (3 raindrops means 10 minutes runtime multiplied with 3).

Valve 2 starts still at 8:10 and runs till 8:40.

Valve 3 starts at 8:20 and runs till 8:50.

So between 8:10 and 8:40 too many valves are opened.

Apparently the delay I entered is not multiplied by the rain drops - is this how it is ment to work ?

I really liked the approach of the raindrops, since it accommodates for the increased water requirement in the summer months - but how should this be set up ?

Thanks a lot for any help!

Hi, I have exactly same problem as Alex mentioned.

I have 16 sprinkles in 5 section on same P1 plan. I need to run each sections separately so I set one rain drop and delays.

But to protect water pump I need to keep it running. It means the pause between running section I not works for me. I set 5s margin in section switching.

Now I figured out to set 5min for section, and delays 295s for sections. But if I want to increase amount of water I need to change plan for whole week and recount delays. I think same problem will be when finally install moisture sensor and go to automated mode.

In my opinion perfect solution will be to put checkbox for multiplying delays or give any option to set parametr to will prevent start next section until any are open or any plan to run sections one by one.

Hi, Well this is how it is designed to work, the increase of rain drop only affect the watering time but not the delay. (Actually I never thought about making the delay also proportional to the rain drops). I have no particular suggestion to give, just need to increase the delay and have some gaps between valve activation in some months. Thanks for the feedback about the use case. Regards, Angelo
