We determine wind skip (and temperature skip) based on the forecasted hourly data for your controller coordinates, not based on raw PWS data which can have issues with recording true wind data (and sometimes temperature data). The national weather service actually recommends wind meters at a height of 33 ft. above ground level which I don’t believe most PWS users adhere to…
Franz, thank you for this explanation. Now I understand why freeze protection has been invoked for my system when temps never got close to my freeze limit.
While I agree that most PWSs don’t adhere to 33’ recommendation for wind measurements, Rachio is using this data for irrigation systems which are much closer to ground level, where most PWSs are making measurements. I have at least two microclimates just in. my yard, a NWS forecast “for my area” can be way off for both of these. I’d therefore much rather Rachio use my PWS’s measured temperatures and wind speeds than a NWS forecast for my area.
Please consider giving users the option to select use of NWS forecasts or actual PWS data when freeze and wind skip are enabled.
