Hello all.
Can anyone advise how best to plot more data from more than one device on a graph? I have a number of Oregon temperature sensors and would like to plot these in 1 graph. I would also like to plot the measured temperature from an ELV Max radiator valve in the same graph as the Oregon thermometer in the same room.
Thanks
Homer
Hi Homer,
you'll need to define a filelog that contains all sensors/data you'd like to plot, as one plot-definition can refer to one log only.
An example can be found e.g. here:
http://forum.fhem.de/index.php?t=msg&goto=30321&rid=86&srch=fht-own#msg_30321 (//forum.fhem.de/index.php?t=msg&goto=30321&rid=86&srch=fht-own#msg_30321)
Cheers,
Uli
Thansk Ulim,
I've tried this:
define FLTest FileLog ./log/testlog-%Y-%m.log (Study:(desiredTemperature|temperature).*| Roaming:.*T:.*)
and the logfile reports this:
wrong syntax: define <name> FileLog filename regexp
Study is an ELV radiator valve, and Roaming is an Oregon temperature sensor.
Am I misunderstanding the setup?
Thanks
Homer
For me
define BrEnergy_fl FileLog ./log/BrEnergy-%Y.log PV01:(Pac).*|PV02:(Pac).*
worked.
Hello,
sorry, but my english is not so good.

Thanks everyone for your help. To summarise, I had a ELV Max radiator valve (called Study) and an Oregon temperature sensor called Roaming, and I have managed to get these 2 devices plotted onto 1 graph with the following:
in flem.cfg:
define FLTest FileLog ./log/testlog-%Y-%m.log Study:(desiredTemperature|temperature).*|Roaming:(T:).*
attr FLTest logtype temp4temp4temp4:Temp/Temp/Temp,text
define StudyConsolidated weblink fileplot FLTest:temp4temp4temp4:CURRENT
attr StudyConsolidated room Plots
which created a logfile like this:
2013-04-03_22:09:56 Roaming T: 16.9 BAT: ok
2013-04-03_22:10:04 Study desiredTemperature: 14.0
2013-04-03_22:10:04 Study temperature: 19.6
2013-04-03_22:10:35 Roaming T: 16.9 BAT: ok
2013-04-03_22:11:04 Study desiredTemperature: 14.0
2013-04-03_22:11:04 Study temperature: 19.6
2013-04-03_22:11:14 Roaming T: 16.9 BAT: ok
2013-04-03_22:11:53 Roaming T: 16.9 BAT: ok
2013-04-03_22:12:05 Study desiredTemperature: 14.0
2013-04-03_22:12:05 Study temperature: 19.6
2013-04-03_22:12:32 Roaming T: 16.9 BAT: ok
2013-04-03_22:13:05 Study desiredTemperature: 14.0
2013-04-03_22:13:05 Study temperature: 19.6
2013-04-03_22:13:11 Roaming T: 16.9 BAT: ok
2013-04-03_22:13:50 Roaming T: 16.9 BAT: ok
2013-04-03_22:14:05 Study desiredTemperature: 14.0
2013-04-03_22:14:05 Study temperature: 19.6
I created a temp4temp4temp4.gplot file, like this:
# Attribute 'small' is useful for gnuplot/-scroll only,
# if plotsize is less than 800,400
#set terminal png transparent small size <SIZE> crop
set terminal png transparent size <SIZE> crop
set output '<OUT>.png'
set xdata time
set timefmt "%Y-%m-%d_%H:%M:%S"
set xlabel " "
set ytics nomirror
set y2tics
#set ytics
set title '<L1>'
set grid xtics y2tics
set y2label "Temperature in C"
set y2label "Temperature in C"
#FileLog 4:temperature:0:
#FileLog 4:T\x3a:0:
#FileLog 4:desiredTemperature:0:
plot \
"< egrep "Study temperature" <IN>"\
axes x1y1 title 'Measured temperature' with lines,\
"< egrep "Roaming T:" <IN>"\
axes x1y1 title 'Actual temperature' with lines,\
"< egrep "desiredTemperature:" <IN>"\
axes x1y1 title 'Desired temperature' with lines\
I know this gplot file is custom (not generic) but it does give me the graph I was wanting.
Does anyone have any comments? It's difficult to determine if I'm doing this the right way because (as a number of people have commented) the google translate isn't great (!!) and my understanding of German is even worse! I really thank all of you non-native English speakers out there who take the time to read my posts and try to help. Fhem is starting to control my home in a great way. I just need to understand it better (and perl etc).
Finally, if anyone has any comments on the above, and how I could add a fourth plot (the boiler status) that would be great. The boiler switch is a Homeeasy appliance switch (that I plan to modifiy). It's setup is:
define boiler TRX_LIGHT AC 0017B62607 BOILERCONTROL
attr boiler room Heating
How can I get the on/off status from a log file into a graph?
Thanks
Homer
