If the data can be exported to something like CSV, it can be plotted using gnuplot into a nice ASCII art.

Data-example (incomplete):

Gnuplot-file for this:

set title "Bedroom\nTemperature BME"
set datafile separator ";"

# Set virtual terminal size to 120x30 and print to STDOUT
set terminal dumb size 120,30

set xlabel "Logtime"
set ylabel "Sensorvalue"

set xdata time
#set timefmt "%Y-%m-%d"
#set xrange ["03/21/95":"03/22/95"]
set format x "%d.%m\n%H:%M"
set timefmt "%Y-%m-%d %H:%M:S"

set key autotitle columnhead outside

plot "bme.csv" using 1:2 title "Room temp(Celsius)" with lines, \
     "dht.csv" using 1:4 title "Oven temp (Celsius)" with lines
[download]

"bme.csv" using 1:2 specifies the filename and which two columns to use for a given plotline (first one is always the timestamp in my case). You can use the same file with different columns, or use different files altogether.

Result:

                                             Bedroom
