Thanks to all the developers that put this out there. You guys are awesome. I got this loaded on a linux server. I managed to get my swiss flow sensor on my arduino talking to linux via python and populating the mysql table. You guys did 99 % of the lifting and made it easy for me to figure...
Thadius, I was playing around on your live site and believe I found a bug. Not sure if you taking issues on github. I know you guys are busy tying things. So I will not post new issue unless i get the go ahead from you.
Thanks to all you guys for the awesome work you are doing.
