I understand that many of you have concerns that your flex schedule is watering too frequently, and apologize for not responding sooner. I want to be very clear in reiterating what @franz said in a very early response to this post- which was that nothing has changed in regards to algorithms. After reviewing a few accounts that had reported higher ET values and more frequent watering than last year, it was discovered that there was actually very little to no difference compared to last year. This can be seen in post #18.
@control4reak, I am sorry that our lack of response caused concern on your end. There are a couple reasons that these responses take longer. One of which is that because flex is a more complex system that has many variables, it takes a while to identify where things are going wrong. The second reason that this post in particular is difficult is because there have been no changes, and it's very involved to pull the yearly data that Franz pulled in a previous post. Third, and finally, things are just pretty busy here over at Rachio! Season is in full swing, the community is at an all time high for engagement, and it is taking a little more time to get back to questions- especially complicated ones like this!
All of that being said, I do not want to dismiss these concerns especially because I know this group is very tuned into their systems. If you would like us to look into your system to compare your ET values, and you have not changed any zone settings that would affect flex scheduling, please comment below. For a more immediate fix, I recommend dialing your crop coefficient down to make your waterings less frequent.
