Log shows less runtime than planned


#1

I’ve noticed recently that Iro is running my zone less than advertised. The flex schedule shows this zone should be watered 60min each time but the log always shows 3 cycles of 19min. I could understand if there was an issue dividing the number if it were say 59min but 60/3 is a whole number so why isn’t it doing 3 cycles of 20min? My other zones are off by 1 min but they have run times that have fractions after being divided by 3.

@GregS Maybe the 60 min is a rounded number too, say 59.6 min rounded up to 60 min ?

I’m pretty sure this is just a display/rounding thing. I seem to remember Franz once saying that the Rachio actually uses seconds and not just the minutes.

I also have one flower zone that Rachio says is going to water for 6 minutes. It turns on at 8am and turns off at 8:06 am, yet the watering history for it always says that it watered for 5 minutes.

Yea, you’re probably right. The timestamps all show an endtime that is 19min after they start but all 3 cycles plus the 2 30min cycle-soak times end 1hr 59min after it starts. It’d be less confusing if they actually rounded instead of just chopping the decimal off.
