While You're At It (Merging Flex and Fixed Schedules)


I think the realization is that with flex scheduling, and in the old days where no has water restrictions, it’s a simple provide start time and your done.

In today’s times, flex scheduling made useful for all areas of the country (maximization of sales) means that you’ve got to develop all of the ‘don’t water now’ stuff.

How ironic from the old days of ‘water every 3 days starting at 7 AM’

Best regards,


I just ordered the 2nd gen unit, and was looking into more detail on the support for water restrictions and came across this thread. I thought I’d add our current local restriction info in case that helps with product development of the new features:

Residential homes with an odd number: Wednesday & Saturday
Residential homes with an even number: Thursday & Sunday
No watering on Mondays
Commercial facilities (apartments, condominiums, civic, commercial, industrial) Tuesday & Friday.

Limit outdoor watering to between midnight and 10 a.m. or between 7 p.m. to midnight on designated watering days. (Exceptions: New landscapes. During the first 10 days after installation, you may water once a day; for day 11 through 20, once every other day; for day 21 through 30, once every third day. Keep receipts on all new landscape purchases.)

Thanks. I look forward to not having to worry about watering anymore :wink:

Thanks for this. We do support the above restrictions (inclusions) for days of week.

We don’t currently support the notion of end before. We will support before, multiple start times, and some other configurable things that no other controller can do. I’m expecting those features to come out next year.

For our Spring release we are working on a schedule end date and maybe the concept of restricted days…plus we are reworking schedules to make them much simpler and even more efficient.

Thanks again for the feedback.


@docBliny, would you be able to water all of your zones between midnight and 10a on designated watering days? If not, how many hours on average would you need to complete the watering? Just curious to better understand your situation.


Yes, we only have 8 zones, so the time won’t really be an issue (I hope, I haven’t received the controller yet, so I don’t know what it’s going to recommend for times especially during the hot months). What I’m hoping for is that the system will still be smart enough to take the available time slots & required duration into consideration along with the “best” times to water (to prevent mildew/fungus/disease).


To add, our watering days are the same odd/even all summer with the exception of no watering on July 31 nor on Aug 31.

One scenario we have been dealing with here in central TX is some areas being on 1-day per week restrictions.

Mid-summer time requirements for a rotor zone (0.4in/hr) for St. Augustine grass when the ETo is 1.7in for the week, comes out to 2hrs. If you have more than 5 rotor zones, you are SOL on getting everything in from midnight until 10am. Have more than 7 and your SOL getting it all in with both morning and evening windows.

I’d love to see an advanced feature that provides a priority value for each zone. High priority gets first shot at full time, low priority zones get the remaining time divided up evenly.

@docBliny, the controller currently does not account for time of day (hourly) restrictions, but this is in our backlog. Further, accounting for the “best” times to water is also in our backlog. At the moment, we’re working on combining our Fixed and Flex schedules. For more information, please see this community post. The new schedules will be able to forecast your schedule for the entire year, so you’ll be able to see what the watering durations and intervals will be by month.

@JeremyInMT, is this restriction only effective in the months of July & August? If I’m understanding correctly, you’ll need to enter restricted days by actual date?

@SmartWaterTX, valid concerns. Our scheduling algorithm factors your crop (turf) coefficient and microclimate to calculate the landscape coefficient, which when applied to ETo (Reference ET) provides your Landscape ET – which is used to calculate the inches of water to apply to the lawn.

Love this idea and it’s currently in our backlog. Like a DVR priority for which TV shows to record if they all air at the same time :wink: Much easier said than done, but a great way to handle schedules with restriction constraints.

@emil Yes, because of where we live, watering on May 31 isn’t an issue and October 31 is nuts! :slight_smile: I would suggest something like being able to right-click on a date in the calendar and choose “Do no water on this day” or something of that ilk. As for the phone interface, I’m not really sure. This is throughout our whole state though, so it’s not just me. Thanks for taking the time to communicate about it, emil!

@JeremyInMT, that would be pretty slick for irregular no watering days

Restrictions create quite the list of edge cases to develop scheduling rules for. Maybe someday restrictions can go away and everyone just uses a Rachio :wink:

I think the opposite is going to occur because water problems are increasingly rising to the top few priorities of many multi-state, state and metroplex areas.

And if I was an investor of Rachio, or part of the executive team running Rachio, I’d be worried that some other competing product will come along, understand how critical water is becoming, and undersand that irrigation controller programming has to be done in reverse of the classic controller. Now what’s needed is sophisticated programming for when not to water - by zone, by grass type, by drip technology, etc.

Best regards,

@emil Yeah, I’m sure the options get pretty complicated when lumped together. Maybe it could be thought of as a “standby” day or something. You guys just keep up the good work. I’ll throw things against the wall and see if they stick, lol!


Amen. I would be using less water if I could let the Iro do its thing without restrictions. Interesting when regulations cause the opposite of their intent!


They so often do! The law of unintended consequences. :cry:


Yea Steve levit and Steve dubner covered this very well in freakonomics

Any word on this? I’d love to be able do eliminate the need of remembering to do a rain delay the day before this happens. Seems like if you could just intersect restriction days with the watering schedule so it wouldn’t run, at least on a fixed schedule which is what mine is.

have you investigated an ifttt recipe that monitors a google calendar? was curious if that did not provide enough flexibility for you

I haven’t investigated IFTTT much after its lousy, albeit unrelated, geofencing capabilities. This just seems like something that should be part of the software and not require a second app that requires access to a calendar. This feature should be really easy to implement against a fixed schedule. With the water as needed stuff I have no idea though. Restriction days are such a big thing that I’m surprised this wasn’t a first-release feature really. Thanks for the idea though and if Rachio can’t add it I may have to resort to this method. :cry:

well, i think the idea is when enough ppl have your need/problem, it will be exposed via the app. not saying you are a statistical anomaly but for the moment, you are not the majority.

for now, rachio at least provides an avenue via ifttt. and its not too bad, if you sync the calendar to your phone, but yes, you do miss that feel good rachio feedback loop that the rocket has been fueled and the boosters have been ignited.

I’m the person that started this discussion, requesting consideration for implementing of a ‘pause’ period of time capability.

I.e., specify watering start at 1 AM, and be able to specify a ‘pause’ period as 10 AM - 6 PM.

On a hot day with a large property, watering starts at 1 AM, continues up to 10 AM, ‘pauses’ until 6 PM, resumes at 6 PM, and finishes before midnight.

This would be maximum simplicity. No IRRT or anything else - just the Iro.

If a ‘pause’ capability isn’t cost effectively implementable, then the customer simply has to do the math long hand. Figure out how which zones can be watered between 1 and 10 AM during the hottest day of the year. That’s one schedule. Then do the remaining zones after 6 PM.
