Thanks both for replies. I know it is unusual but the temperature readings at height are not the same as at 2 m. I'll probably read Ecowitt from file and log in some extraTemp field. I hope it is possible to change the NOAA template to use e.g. extraTemp5 instead of outTemp -- I'll look into that. I'd optimally generate a native one and the one with the Ecowitt temperature sensor. I'll run another weewx instance (for the Ecowitt sensors) in parallel for sure. I'll probably have to switch to Ecowitt in full at some point.
