Product Description
ET System Gathers weather data on site, continuously self-adjusts to calculate the ideal program for your landscape. Take the guesswork out of irrigation scheduling, by using your own state-of-the-art weather station to track your local microclimate and automatically calculate a scientific irrigation program! The Hunter ET System is an easy-to-add-on accessory (for any Hunter controller that operates with a SmartPort® system) that measures key climatic conditions, and uses them to calculate your local Evapotranspiration (ET) factor. ET is the combination of two separate processes whereby water is lost from the soil surface by evaporation and from the plant by transpiration. By taking into account the rate at which water is consumed by weather conditions, the ET System will initiate a new schedule to replenish only the water that is actually needed for your sprinkler system, plants, and soil conditions. And our WiltGardTM technology can intervene to trigger protective watering when extreme conditions threaten your plants. The result is a dramatic savings in your water bill (about 30%, on average), healthier root zones, and your participation in conserving our precious natural resources.

Works OK, but too many failures
By Ralph
I have now had one of these for 3 years. We used water savings rebates to both install rotator nozzles, and go to a smart controller. We are in Southern California, about 2 miles from the ocean, so summer water needs fluctuate a lot depending on whether the coastal fog comes in or not. I thought a smart controller that used actual weather at our house would be a lot better than one that used generic weather, so went with the ET System, with the wind sensor.Installation was pretty straightforward - the harder part was finding a place to put the weather sensor, and I ending up putting in an 8 foot pole to mount it on. When I first got it I had some setup problems, although in hindsight it might have only been errors in the user manual that confused 50% sun with 75% sun, but the result was that initially I could not get it to water enough. Hunter said they had a new revision, sent me a complete new unit, and things seemed to work a lot better.It did take a while to get the controller set up correctly - I found that there are many settings, but not a lot of info on what those settings do. For example, choosing between 'sandy loam' and 'loamy sand'. I'm still not sure which we have, and there is nothing that helps figure out what options put out more water, or what options water more frequently. Hunter was not a lot of help on that either - basically their advice is to try it, and then try something else if it does not seem right. The unit also has lots of setting for vegetation types, but nothing for a vegetable garden, which we have on a separate zone. I ended up going to some advanced setting to try and get the tomatoes enough water.We did save water, although how much is due to the ET System and how much is due to replacing the spray nozzles with rotator nozzles I don't really know. My total water bill went down by about 35%, subtracting out our base usage in the winter, I figure the irrigation component went down by close to 50%. The nozzles are supposed to save about 30%, so another 20% from the smart controller seems likely.The best part about the smart controller is that once the setup is keeping things green, you don't have to change anything from summer to winter, or when it rains. The controller does more watering when its needed, and less (or none) when its not. So that part is great.However, in the 3 years we have had it, the weather sensor unit has failed twice, about 18 months apart. The first time it was getting an erroneous signal that it was raining all the time, and it took a while to figure out what was going on, especially since we did have a bit of rain, and other than things turning brown its not too easy to see that there is a problem. You can retrieve the water history for the last week, but its pretty cumbersome to walk through that. Most recently, we were away for 3 weeks, came back to a lot of brown, the sensor unit had failed, and the main controller was reporting a connection error, so it was easy to see there was a problem. In both cases Hunter sent a replacement sensor unit promptly, and since I'm handy it was pretty easy to swap it out. But somehow, I don't think that a $500 unit should fail that often, regardless of what the warranty says, or how responsive customer service has been. On this latest replacement, Hunter did say that they have improved the unit to make it more reliable.If it wasn't for the failures I would give it 4 stars for sure, just hope that it stays working now. Would I buy it again, without a water savings rebate? Maybe. Our water usage is coming down anyway as we replace grass with drought tolerant plants, so the dollar savings are not as big as they used to be. I estimate the controller saves $300-$400 per year, compared to what we used before the smart controller. We could probably get a lot of that savings by paying more attention to the water times, and adjusting them frequently. However, the convenience is worth something as well, so I'd have to think about that and look at the alternatives.
