WeatherCat Version 4.0.0 early dev release #3 is now available for testing. See https://athena.trixology.com/index.php?topic=3677.0 for more details and download.
It is moot whether WeatherCat can handle two soil stations, because the Davis Console/Envoy can't. I bought a used second station to use as a remote temp sender, and then found that the receiver can't accept the second station.Sorry,Steve
