Hi There! I am working on my wind sensor currently, so far I have tuned my data to be emitted the following way (My weewx record interval is 5min):
*When there is some wind:* Every five 5min, sensor will emit average windspeed/dir over last 5 minutes and max windgust/gustdir observed on a 10sec interval during the last 5 minutes. I tuned this way because I want to make sure weewx will record any extreme windgust I measure. If I send more than 1 sample of windgust in 5min period, weewx will average them to build its database record. (as far as I understood) *When there's no wind:* my sensor will emit a zero speed value every 15min to save battery, so it will miss ~2 database record over 3. I guess it's not a big deal as there's no wind. While writing this, I wonder if those missing "0" speed samples can affect some calculations, like average wind ? Anyway: due to those timings, It happens that I have no wind data on current database record: meaning $current.windSpeed will sporadically give N/A value (more often when there's no wind). I was expecting $latest.windSpeed to give me the last value recorded (in my situation 5-15min ago). But apparently, it's not working this way ? Is there a workaround possible ?
