What are virtual sensors?
A virtual sensor (where the name starts with VS_xxx) is a sensor that takes its value from a formula that is typically calculated based on historical data. Not all weather stations are the same and, while one station may send total monthly rain, another may not. To help WeatherWizz members bridge this gap, we have created virtual sensors, which calculate these for you.
It is important to note that new accounts have not yet collected historical information, so the value represented may not be accurate or as expected straight away. Depending on the type of sensor selected, it can take hours, days, or even months for the virtual sensor data to be fully compiled and calculated accurately.
Why do I not see all of these virtual sensors?
In order to calculate a virtual sensor, your weather station must be reporting certain information. For example, WeatherWizz could not calculate the day minimum temperature (VS_TempDayMin) if your weather station was not sending the outdoor temperature.
VS_TempDayMin
The lowest temperature recorded for the current day.
VS_TempDayMax
The highest temperature recorded for the current day.
VS_DayMaxGust
The highest gust value recorded for the current day.
VS_DayMaxAirPressure
The highest air pressure value recorded for the current day.
VS_DayMinAirPressure
The lowest air pressure value recorded for the current day.
VS_DayAvgAirPressure
The average air pressure value recorded for the current day.
VS_DaysSinceRain
The number of days that has passed since your rain sensor last recorded rain.
VS_RainDaysThisMonth
A count of the days where the rain sensor recorded rain for the current month.
VS_RainDaysThisYear
A count of the days where the rain sensor recorded rain for the current year.
VS_RainMonthTotal
The accumulated total rain recorded for the current month.
VS_RainYearTotal
The accumulated total rain recorded for the current year.
VS_MaxRainRate24Hour
The highest rain rate recorded in the last 24 hours.
VS_MonthMaxTemp
The highest temperature recorded for the current month.
VS_MonthMinTemp
The lowest temperature recorded for the current month.
VS_MonthMaxAirPressure
The highest air pressure recorded for the current month.
VS_MonthMinAirPressure
The lowest air pressure recorded for the current month.
VS_MonthAvgAirPressure
The average air pressure recorded for the current month.
VS_MonthAvgAirPressure
The average air pressure recorded for the current month.
VS_YearMaxTemp
The highest temperature recorded for the current month.
VS_YearMinTemp
The lowest temperature recorded for the current year.
VS_APTend
An enumerator value representing the current air pressure trend. 0=Falling, 1= Stable, 2 = Rising
This sensor can be used in conjunction with the sensor rules to translate the numerical value 0, 1, or 2 into text such as ‘Falling’, ‘Stable’ or ‘Rising’ or in your own language.
VS_MonthAvgMaxTemp
The average maximum temperature recorded for the current month.
VS_MonthAvgMinTemp
The average minimum temperature recorded for the current month.
VS_MonthAvgTemp
The average temperature recorded for the current month.
VS_AbsoluteRainTotal
The total amount of rain recorded since using WeatherWizz.
VS_feelslike_celcius
Displays Wind Chill or Heat Index for stations that send temperature in Celcius.
VS_feelslike_fahrenheit
Displays Wind Chill or Heat Index for stations that send temperature in Fahrenheit.
