I have a “regular” OpenSprinkler with firmware 2.1.6 (1).
I wanted to use the Zimmerman method for adjusting watering times automatically. I obtained a Weather Underground key, and set the Adjustment Method to “Zimmerman”. Then I used the Weather Diagnostics window to see the effect.
Everything seemed to work, except that the Zimmerman formula does not work well for my area (gives far too much weight to humidity). So I headed back to the options screent to adjust the weights of the formula. However there’s no “Adjustment Method Options” to be found.
I verified that it’s not just a UI glitch, by using the API to retrieve all the settings (ja) – there’s no “wto” parameter in the settings. Attempting to set the “wto” parameter always returns result code “1” (success), regardless of the value provided, but the parameter is not actually set (still missing).
I tried to Factory Reset, but results are the same.
Any idea how to get the Adjustment Method Options to show up?
