I will second this device for a serious win in the irrigation and water savings department.
First of all, the customer service is excellent. There is only one other app that has a forum and email support that is as good as Rachio's. It is a photo app and I am leaving out the name for obvious reasons. If you want to know about it, PM me.
This device has given me total control over my irrigation needs. I am a lawn nut as my wife calls me. I spend a lot of time on my lawn and the Iro has showed me many mistakes I was making. My controller went after 7-8 years and I can tell you. My lawn is looking the best it has in a long time. Water budgeting, cycle soak, the reporting and of course, turning on the sprinkler while someone is in the yard and I am work. Is a lot of fun.
No more running from the controller to the back yard to see if something is wrong.
No more turning knobs on an outdated controller and trying to decipher a wiring schematic.
No more trying to figure out whether or not the rain sensor is working properly. (Meaning, if my rain sensor fails, the Iro will still check the weather and skip a watering if needed).
The ability to know that the lawn is getting the proper amount of water and I am watering less.
The ease of hooking this up and setup with my neighbor was a breeze. Took me longer to take out the old Hunter controller than it did to hook up the Iro.
Call customer service and you get some one who knows what they are talking about. Email customer service and you get a response almost immediately (there will be exceptions to this).
Seeing forum members running landscaping lights off the Iro,
Integration with nest and other home automation apps.
Oh yeah, it looks great too. You would not believe how many folks are in my garage and they ask, "What the hell is that on the wall?" I take out my phone and just press a button to turn on the sprinklers! It's like a new toy......
I agree with @plainsane, this device is top notch and worth every penny. I cannot wait to start looking at water bills and hopefully see some savings.
It can be a little confusing at first with some big terms and math. But hey, once you figure it out. You are good to go.
Future idea for me would be a new product in the sprinkler head department. If we could create a wifi enabled sprinkler head to communicate with the Iro. Then we would really be cooking with bacon. Imagine the data we could pull from some wireless sprinkler heads that send data back to the Iro.....
Water pressure, spray radius, maybe calculate the amount of water coming out of the head and each zone. Built in soil sensor and a way to track soil make up and the amount of moisture retained in the soil to assist in taking water budgeting to the next level. Yeah I know, I just made someone a millionaire with this idea. What cna I say, I am married with 3 boys that run me all over with athletics school. Yes, I am living the American dream.......
All in all a great product, keep up the good work, no great work!
