My first thought was exactly as @rlithgow1 stated. Other ideas:
Custom water feature effects (possibly paired with laminar flow and lighting)
Making kids time dashing through the sprinklers much more interactive
Special effects for Halloween (giant spitting monster or "splash zone" effect)
"Put out the campfire" mode once you go to bed
If you still have unconnected zones you could make much more custom water-controlled features or things you might want.
5) Refill the bird bath(es) or outdoor water dishes
6) Rinse the car/driveway off
7) Make a cooling misting booth (or swamp cooler)
I use Rainmachine that is integrated with Hubitat.
Although, I do not Hubitat to operate RainMachine I am using Hubitat to let me know when the sprinklers are starting and I have a rule which is opening all the sprinklers ( without opening the main valve) in order to discharge any water from from the plumbing when the leak sensors are detecting any water leakage in the house. That will take away all the water pressure which helps in limiting further any accidental water damage. If you have a multi level house and your water leaks is on ground floor or basement is even more effective.
I have a Rachio and love the flex scheduling. One thing I am going to look into for this summer is ensuring that watering is skipped on Friday mowing day. I should be able to do that with Hubitat and webCoRE (where I write all my rules).
Also, I like the Rachio Community integration on Hubitat simply for the weather display on the dashboard. It will also indicate watering days. It's nice to see that stuff at a glance. (Plus, I designed the weather icons. )
Ooo. If you figure this out, would love to see how you do it. As I'm a bit nervous to muck with the Flex days (love those too) with manual overrides on my own.
I am SO tired of the asymmetrical feature roll out that some companies follow - available on this phone, but not on that phone or the web site. I have both iPhones and Android phones so I can get to whatever I need, but tiresome when I have to remember where I can do something...
I'm another person who has integrated my irrigation control (Rain Machine) but I allow Rain Machine to do it's thing - I have it tied into my local Ambent weather station for weather-based scheduling, and it does a very nice job of watering when it should, and skipping or reducing when it should. Very happy.
I would like to set up a dashboard at some point so I have the "at a glance" view as well, but time to do so just isn't there at the moment.
Don't water some zones if wind is 10+ mph (it just blows the water on the driveway).
Stop schedule based on rain and chance of rain.
Change schedule based on seasons of the year.
I have a neighbor that walks two huge German Shepards, and I've seen him a few times carrying the giant black Glad trashbags...huge blobs of "treasure" rolling around inside.
I have tiny dogs (required by tiny wife) and I carry equally tiny little bags. One of the few benefits of small dogs.
I have actual rain sensing connected directly to my ambient weather station I have in my backyard. So I get an actual measurement of rainfall where I live and then that is fed into the rain machine for it to adjust watering.
I also have a couple weather services tied into the rain machine so it also will look at forecasted weather and adjust for that as well.
I have implemented a simple rule that when the main house water valve is closing (due to any of the leak sensor detecting an water leak) then the sprinklers will open for 5 minutes. This will drain most of the water from the house since we have a double storey house. In the end any remaining water in the pipes will not be any longer under pressure. Thus limiting further the volume of water lost at the point of fault inside the house.
I have some WIFI (non-hubitat) sprinkler timers. Ive created Node-Red logic that uses a Weather Forecast API, adds any water (rain or sprinkler) from the previous day to determine how much (or skip) a watering for the current day.
