Hello,
It would be great if you could set the irrigation valve to close once a specified amount of water (measured by the flow meter) has been dispensed. In other words, control based not only on time but also on the amount dispensed.
The reason is simple: many plants do not need a certain amount of time for watering, but a certain amount of water. For example, I have to water my newly planted apple trees with 30 liters twice a week. However, the water delivery through my delivery system is too inaccurate to calculate the amount delivered from the watering time. Today, for example, 30 liters were delivered in 30 minutes, another time 40 liters.
A compromise solution would be to use the normal time and valve opening time, but also the maximum amount of water. The valve then closes when one of the two parameters is met (i.e., either the time has elapsed or the amount of water has been dispensed).
This would allow the current program logic to be retained.
This feature would probably not be too complicated to implement. I would then simply enter 60 minutes and 30 liters (in the above example). This would ensure that 30 liters are always delivered – sometimes it takes longer, sometimes it is faster.
Incidentally, this would be a feature that no other irrigation system has (neither Hunter nor Rainbird, as far as I can tell)!
Best regards,
Peter
Thanks for proposing this feature. It’s possible to implement it, but at the moment it will only work if zones run sequentially (i.e. no two zones run at the same time). Some users open multiple zones at the same time, and since there is only one flow sensor for the entire system, when multiple zones are running together, there is no easy way to derive the flow amount for each zone (unless if we make the assumption that the flow is evenly divided among all running zones). So if we implement the feature, the implicit assumption is that no two zones can run simultaneously.
Thanks for the quick reply… unfortunately, the notification ended up in my spam folder and I only saw it now.
I’ve already thought about that. For me personally, the sequential execution solution would be perfect.
You then have to decide: if you want a consumption-controlled system, you have to switch the valves sequentially. I would be very happy if this feature could be implemented.
