The format of each variable name is as follows:
   <timeframe>_<sensor >_<dimension>[_<unit>]

<time frame>  = The reported sensor data was measured in this period
timeframeDescription Recalculation
actualData last seen from the sensor
alltimeNot documented in the manual!---------------
day1Data of the actual day (including min/max values)Updated every 5 minutes
hour1Data of the actual hour (including min/max values)Updated every 5 minutes
last15mData of the last 15 minutes (including min/max values)
Not documented in the manual! Updated every 5 minutes
last24hData of the last 24 hours (including min/max values)Updated every 5 minutes
last60mData of the last 60 minutes (including min/max values)Updated every 5 minutes
month1Data of the actual month (including min/max values)Updated every 6 hours (00:13/06:13/12:13/18:13)
year1Data of the actual year (including min/max values)Updated every day (04:47)
seq????List of data that are used by WD Live to generate weather graphs
Always starts with the last completed timeframe e.g. seqday1 starts yesterday (and NOT today)
The number of measurments varies per sensor_dimension, therefore a table is icluded here.



There are two kind of sensors: <Sensor>  Weathersensor information

wind#Data of wind sensor with id #
rain#Data of rain sensor with id #
thb#Data of thermo/hygro/baro sensor with id #
th#Data of thermo/hygro sensor with id #

uv#Data of uv sensor with id #

<Dimension>  For each sensor only a subset of dimensions is available.
