New NetHome Item
There is now a new NetHome Item in the nightly build: UPMSoilMoisture. It is really a variation of the UPMThermometer, but designed to use the UPM thermometer sensor as a soil moisture sensor. You can specify the levels for 100% and for 0% humidity (as they will vary depending on the impedance in the soil you use) and the UPMSoilMoisture-item will calculate a humidity percentage value from the impedance. It keeps track of the highest and lowest “raw” values that it has seen to help setting the 100% and 0% levels. The accuracy is not brilliant, but you get a pretty good understanding of when it is time to water the plant...
