It seems like most homes have sprinkler systems and if they do, they have some form of controller to automatically turn the water on and off for the time and days you feel necessary. It seems like basic functionality and if it isn't broken, you may not feel the need to replace it.
Today, there are so many smart home devices that are not only convenient, but they'll end up saving you enough money to pay for the upgrade. There are different manufacturers, but you should at least consider the Rachio if for no other reason than the easy installation procedure.
The process is simple. Unplug the old controller and disconnect the wires being sure to label which wires went to which stations. Using the Rachio template, mark three spots on the wall, drill holes in the drywall, insert the anchors into the holes and screw the new controller to the wall.
This model has convenient wire connectors that do not require crimping a wire around a screw. It is quick and easy to put the numbered wires in the corresponding slot. The directions are simple and easy to follow. When complete, connect the power source and plug it into a wall socket.
Now, install the Rachio app to your phone and continue following the instructions to connect the controller to the Wi-Fi. In minutes, you'll be sitting in a lawn chair making adjustments and seeing what it will do.
Some of the features you'll find very convenient are the multiple schedules that can be created and easily switched from one to another. As you set up each zone, you can take a picture of the area and be able to identify with a glance which area you want when individually selecting one.
Another thing you might like is that when you're trying to track down a broken head or just need to adjust it, you can turn on a zone from your phone while looking at the yard. When you identify which head is the culprit, turn the water off from your phone, make the adjustment or repair and turn the water back on to test it without having to go back and forth to wherever your controller is located.
Rachio will even monitor the weather to skip a scheduled cycle in case of rain, high wind or freezing temperatures. You could literally be anywhere in the world where you have an Internet connection and you'll be able to adjust your watering cycle. This device really does save time and money while being fun to operate.
