Auto Seasonal Adjustment is applied twice

I have had the WiFi LNK for about two weeks now and I thought I was nuts when the seasonal adjustment was being applied to the programmed time and then applied again to get he adjustment. So a zone with a summer run time (100%) of 10 minutes with an auto seasonal adjustment of 50% gets moved down to a runtime of 2 minutes....this repeats each night until the programmed time is eventually down to zero. I had to turn off the auto adjust. I called Rain Bird support and had three calls with them. I had the impression this was a new problem, but I come to the app reviews and see comments that this same behavior was happening in July of 2020 and here it is November and it still doesn’t work. This is seemingly a simple math problem with the fix being that y’all need to program it so that it doesn’t change the programmed time at all and only changes the adjusted time. The user sets the program time...don’t change that! Adjusted time equals program time multiplied by seasonal adjustment. The program time should stay the same. It’s that simple!

Edit 1: Dec 2, 2020 As of release version 2.16, my ESP-TM2 controller now appears to be functioning correctly with respect to the automatic seasonal adjustments pushed out by Rain Bird. I’ve changed my rating accordingly. I’m not certain, but I believe it also pushed a firmware update to the LNK WiFi module.

For the price good App

I use thus App for several customers. It has easy to use features and many of my elderly clients can use it more conveniently than the actual controller on the wall.
My favorite feature is the rain delay I am not sure why it was moved in the recent update not that’s ok.
Regarding set up, If you are having problems it is easier to buy a20-50 WiFi booster and set to 2Ghz to get it to link. Sometimes if you have a high end security system with complicated fire walks, then all bets are off and you need the customers tech to assist in set up.
I would give this app 5 stars except for the poor attitude of the customer service. ALL other issue I have called RainBird about I have been treated with professionals but for some reason the folks that work the App customer service A. sound like they are reading from a script and have no clue what they are doing. B. 2x I have explained the problem and because they take sooo long (and I am standing in a hat garage in Houston Tx) I have asked them to email suggestions or call me back they say “No I need you to wait”. I would like it them to either come stand in the garage with me while they continue knowing nothing or realize they need to figure it out later and call back.
Once it was a bad door another time it was the clients WiFi had been changed and she did not know it.

Needs improvement

First off, when you name your sprinkler zones it does not allow many characters even though the box for the entry is quite long. Second, any scheduled program supersedes all other functions, so if you are manually watering and a program start time is scheduled during the manual watering it shuts the manual watering off and starts the scheduled watering. You can remove start times but you will get an alarm message on your controller and magically mine reverted back to the original start times. Thirdly the app is slow at keeping up with the controller. For instance it will display that you are on a specific zone but you need to wait a few minutes for it to sync and show the actual zone and watering time. Lastly, don’t trust seasonal adjust or you may have a brown lawn. It’s still a handy app it just needs more work…..oh and the rain sensor..hmm had to turn it off. It says it’s raining on a beautiful sunny day
