Hi!
You could silent the unknown params line with a
FWD_IGNORE = softwaretype,indoortempf,indoorhumidity,baromabsin,maxdailygust,solarradiation,rainratein,eventrainin,dailyrainin,weeklyrainin,monthlyrainin,yearlyrainin,totalrainin,temp1f,humidity1,wh68batt,wh40batt,wh26batt,batt1,windchillf,feelslikef,heatindexf,windspdmph_avg10m,winddir_avg10m,windgustmph_max10m,brightness,cloudf,sunhours,sonnenstd,suncomb,ptrend1,pchange1,ptrend3,pchange3
in your Forward-5.
These keys will not be sent to Windy (ignored) afterwards.
But this is not a must - Windy just ignores unkown parameters.
