WeatherKitten (WeatherCat iOS client) V1.0.0 B97 is now available in beta! See https://athena.trixology.com/index.php?topic=3714.0 for more details.
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
