Based on the data, I want to get a few works done. At the moment, I have a
couple of job running and the third one is planned.
i. Bash: executes audio warning when the heat index goes beyond certain
value (my place gets too hot with high humidity)
ii. Bash: push email notification when there is heavy wind or rain
iii. Bash: this is yet to be done: When the temperature difference (outdoor
vs indoor) exceeds 5 degrees (oC) during the night then my bedroom AC turns
on (although a window is always open for airflow, still the room gets
hotter than outside)
Is there any skin that has an interactive graph? at the moment what I see
is just an image graph.
This is my bash script
