    I do not install systems, just maintain lawns. I was wondering how often rain gauges are installed on systems vs just rain sensors.

    I have a lot of lawns with problems with too much water and I am suspecting no one has gauges.

    There are Rain Sensors that collect rain fall when it rains, if it rains a certain amount ( to whatever the setting is set at) it will shut the system down for a few days.

    There are also Moisture sensors which are probes in the ground that record the amount of moisture in it's area at certain depths. These are much more expensive then rain sensors and often not used

    A wet lawn can be anything from poor soil content, over watering, springs, leaks

    Those lawns should dry out pretty quick with the hot weather out there.

    That's 100% relative buddy. It aint hot here that's for damn sure. Remember you talking to potentially the entire world here. Mostly The US Though

    Make sense now?

    Not often enough. You have to have a controller that will recognize the input from a rain gauge and react accordingly. Most traditional controllers on the market today (those not set up for "smart control") do not accept an input from a rain gauge, but rather a rain sensor. The benefit of a rain gauge with a controller that recognizes it is that the controller will count the amount of rain fall as moisture and prevent the controller from watering until that moisture is used up through ET.
