About the data transmission between the station and the sensors: I also have sensors that are quite far or behind thick walls, with rather poor signal reception. But this has never been a problem for me: the station simply stops displaying any value for the specific sensor, and I don't get any value in weewx, that's all.
So, if the values on your station are always correct but you get 6400 C in weewx, then the problem is most likely coming from the driver. I never tested the algorithm used to convert raw data to meaningful values with temperature around 0°C (or negative values), it could be incorrect. -- You received this message because you are subscribed to the Google Groups "weewx-user" group.
