### Display Light and Sunshine values from a KS550

# This file uses placeholders. For good results the following
# attribute settings in the WebLink object are recommended:
#
# label: "Luminosity"::"Sunshine duration [h]"
# title: "Light $data{currval1} ($data{min1}-$data{max1}) and Sunshine hours $data{currval2} @ $data{currdate1}"
	
### FileLog definition corresponding to this file

# define <filelogname> FileLog /var/log/fhem/KS550_%Y.log <ks550name>:T:.*

### FileLog content

# 2012-01-01_00:00:03 KS550 T: 10.4 H: 97 W: 0 R: 976.45 IR: 0 WD: 40 WDR: 67.5 S: 155 B: 8

# This is the status line, which is printed to the logfile. For each of
# the data there is also a separate line available, which you can select 
# using a different regular expression in the FileLog define. 
# Try .* as an all quantor to see, which lines are available.

# Field description:
# T: Temperature
# H: Humidity
# W: Wind velocity
# R: Rain quantity
# IR: Rain indicator
# WD: Direction of wind
# WDR: Range of wind directions (67.5 is the maximum range)
# S: Sunshine duration
# B: Brightness (minimum:8, maximum:255)

### Settings

set terminal size <SIZE>
set title '<TL>'
set ylabel '<L1>'
set y2label '<L2>'
set ytics
set y2tics

# Maybe define your own ranges (not really needed):
#set yrange [1:10]
#set y2range [0:300]

### Data extraction

# The following FileLog directives extract the values from the logfile
# lines. If you have only the status lines in the logfile, you do not
# need any regular expression, since the line is valid anyhow.
# Notice the delta-* functions, which are called to compute Rain/h and
# Rain/d values by accumulating the changes.

#FileLog 20::0:
#FileLog 18::0:delta-h
