There is a bug on the WeatherLink.com summary page: If you have a soil moisture station, the highs and lows will not report properly. This ONLY happens if the soil moisture station is your only extra station. If you have a temp station or another extra station, the soil moisture highs and lows will be fine. Workaround: Configure the system so that it thinks it has a temp station on transmitter X. This station won’t exist and data will not show up BUT the soil moisture highs and lows will update.
