\section{Preface}
|
|
I did some research on available self hosted solutions for Arduino, as of January 2019. I was thinking of using Thingspeak, but they haven't updated their self hosted git repo since 2016. Adafruit.io is the same but 2017\footnote{And uses node.js :/}. Sparkfun closed down their solution.\footnote{Apparently they have no idea what they are doing, and their solution inevitably blew up. Bloated software...} It seems theother data aggregaters are only interested in people giving them data, so they can then sell it, hoard it like wealth, etc... Another solution is necessary.

\section{Plan}
|
|
Since I've done some data logging with GNUplot before, I've decided to use a flat text file, and csv output. I don't want to deal with MQTT, as this is in a safe LAN (not over WAN), and security is no issue. I also don't want the clients to do any sending. They are stupid, they sit there, and the server is responsible for data collecting. Simple.

What I will do, as I've already started doing, is hosting a web server on the microcontroller, which has amongst other things, sensor data available. The server will pull data from the sensor, and place it into a flat file. GNUplot will run via cron scripts, and the server will host various jpgs. Let's see how this goes.
