Hi ziehlke,

thanks for your contribution. Since in sendToInflux.sh there is only an example of calling the script, I'm quite unsure if this should really be changed. Can you explain your idea behind the change more?

Hello, sure thing! It's mere an example... but to be honest I had not read the whole readme before the first time I run the script. Ended up calling the command from the example file (RTFM !). So I'm thinking... the example command is there... and there are seperate files for all the callbacks... I don't see the risk of handicaping other callbacks and for this particuliar case it's adviced not to include the option... so why the exmaple command wouldn't do this? Anyways, if you think it's not worth it - no hard feelings. Great package, works like a charm. Thank you!
