Love it!

I have pretty much automated everything in my home and this has to be my favorite and most used. The device is easy to install and the app is very easy even for my kids to understand and use. No more spending a half an hour in the basement trying to change my schedule because it’s getting hotter and no more stupid wireless rain sensor messing up my watering schedule. I connected zone to my garden drip system this year and my garden has never looked better. It’s really cool that I can stand in my garden and if it needs more water I can just press a button on my phone. Just yesterday my landscapers wanted to put fertilizer on the lawn but needed me to water it first and I was able to do that from work. The best part is being able to stop watering when I want to take a shower and the water pressure is low because the sprinklers are on. The only problem is that the snooze button does not work for programs that are actively on....if they add that function I would give it 5 stars and paid more money!
So pause button and skip zone button need to be in your next update...Thanks

The concept is great regarding the opportunity to remotely control the lawn watering system - but the WiFi built into the unit is not reliable. All other automated WiFi connections within the home are working fine, but the Rainmaker panel can not hold a WiFi signal. I have had the local cable company who services our WiFi come out several times and the unit continues to fail holding a continual WiFi signal. It is worth the effort to research other similar products within the competitive market before purchasing Rainmaker. They have a 2.8 rating out of 5. That should be concerning to you if making a decision to purchase a unit such as this. I bought Rainmaker without doing my homework and troubles me for not following through on other similar products. Especially with the money i spent for the unit and installation. Best of luck to all! Also the amount of watering this year from the unit saturated my yard and now have water in my cellar. The sump pump was dry for years unit I had this unit installed. It’s a false sense of security and I will eventually go back to a manual watering panel. The developers are dedicated to fix all the bugs, and intentions are honorable, but in the mean time with all the bata fixes and more, my unit is not working! I bought it purposely because I travel and wanted to monitor my sprinkler system from remote!

Poor execution of a good idea

I’ve had the device for over 2 years. It might have been really useful but falls short due to very poor scheduling algorithms. On the surface, they claim to take into account a multitude of parameters like rain amount, evaporation rate, and other factors affecting moisture retention. In reality, the scheduling makes no sense. I’m not sure if basic sanity checks were ever done, let alone comprehensive performance testing. Today we got 2.3 inches of rain as recorded by the connected rain gauge. For whatever reason, instead of using the actual measurement they somehow came up with 1.5 in of rain. Even with that number, one expects that watering should be paused for a while. But no - I have scheduled 150% watering for tomorrow, and 100% two days after that. I had to deactivate the program to prevent this insanity.
In summary - if you need a device that you can manually control with your phone it will do the trick. If you want to rely on some “smart” scheduling you are out of luck. Congratulations - you bought yourself an irrigation system remote! This is why I give some credit to the app - not a bad remote and has some graphs too... LOL

Developer Response ,

Thank you for your feedback.
This is not related to the iOS app. You can ask for help and see how others are using the RainMachine smart irrigation controllers by joining our forum (

Nevertheless, the RainMachine device periodically checks the weather services you are using. Note that our algorithm it's autocorrecting watering times with the measurements taken the previous day.
