Hello! My Rachio has been watering fairly frequently, every 3rd day or so. I was hoping to do better, and the city's recommendation is less often & less water than what the Rachio is delivering. Additionally, the grass & soil never really "dry out".
I noticed today that the crop ET in the Moisture Level report is fairly high. I looked up the local ET report, which is gathered from a location close by:
Compare to the moisture level report in my Rachio:
You can see their Kc is 0.81 for "Standard", and my Rachio is set to 0.80. Allowed depletion is 0.50
I'm using PWS data (http://weather.gladstonefamily.net/site/search?site=AV224). It appears to be a good quality PWS, and Google Streetview shows a very tall mast, so it's likely not mounted under the eaves! I hesitate to use the airport 8 miles away, because weather & rainfall is extremely localized around here, but maybe I should experiment.
Has anyone else had a similar experience? Are there major possible explanations for the discrepancy that I'm not thinking about?
