Hi @canons900, good evening. Thanks for posting!
Great questions. I'll do my best to reply answer below:
The reporting feature will require a few skipped schedules from rain to show any saved water usage. For more information, please see our Reporting support article.
As long as you have the Weather Intelligence feature enabled on your watering time(s), the Iro is connected to a weather station. By default, we link to the nearest National Weather Station (NWS), but this can be overridden to use a Personal Weather Station (PWS) via the Advanced Settings. Please note, PWS are not always accurate and you should observe their data collection for a week or two before trusting one to run your sprinklers. We do our best to weed out bad stations, but we cannot catch them all.
Per the rain sensitivity threshold set in the Weather Intelligence feature (.25" by default), the observed + forecasted rain was not enough to meet/exceed said threshold and the watering time was not skipped. Future watering run times do not change with the current scheduling options. However, in our v2.0 release (coming soon!), we'll be adding FLEX schedules, which will water as needed (pending user imposed restrictions). Each zone will have it's own "bank account" that will increase with "deposits" (watering events, rainfall, etc) and decrease with "withdrawals" (evaporation, wind, etc). A minimum and maximum budget for each zone will be set and the water level will automatically be kept within this budget given watering rules you set. Think of it as automated watering times with real time, seasonal adjustments on a daily basis.
I'm not quite following your run times. Assuming Zone 1 started at 5:30a for 20 minutes, followed by Zone 2 at 5:50a for 19 minutes, then Zone 3 should start watering at 6:09a and end at 6:19a. However, if Zone 3 was scheduled to start watering at 6a -- but couldn't start until Zone 2 finished, then Zone 3 would be queued up to run as soon as Zone 2 finished...hope that all made sense. Perhaps you could share or email our support team [firstname.lastname@example.org] screen shots of your watering time settings and history feed to review in more detail?
We understand! It's important to be able to justify expenses. I believe after a month or two of using the Iro, you'll start to see notable savings in your water bill from skipped schedules and/or flex scheduling. Perhaps we could touch base in July and compare your water bills from May and June of 2014 to May and June of 2015?
Hope this helps. Let me know if you have any other questions I can help answer.
