Wish-list item here.
Using the pre-defined nozzle types should get most users reasonably good watering times, but currently this doesn’t account for:
- variations in precip rates of nozzles of same type (e.g. MP-rotator is 0.4in/hr vs the 0.7in/hr for “rotary nozzle” in the app)
- improperly designed irrigation systems, where nozzles may/may-not overlap, or have uneven coverage, resulting in different precip rates
- mixing different nozzles on same zone (just saw this mentioned on another post)
- variations in precip rate due to variations in water pressure
So the calculated run times may not be optimal based on the above factors.
For twenty bucks anyone can get catch cups (for example: http://amzn.com/B00CBZB8U8, or maybe even make their own) and do their own irrigation audit. This will let them find out exactly how much water is being applied in each zone, taking into account all real-world factors. Would be awesome if I could input this information into my Iro configuration to have it fine-tune the run times based on actual (observed) precip rates, rather than estimates based just on nozzle type.
