Sensor logging for distributed systems


Hello,

for building up my smart home application I want to integrate several sensors (e.g. temperature sensors) into a common structure by using a standardized interface.

I want to develop a package being able to manage sensors of the house. Some of them may not be on the same machine. I am thinking of a file based or a distributed IP based network structure.

I have found a package "lm-sensors" doing this for local sensors of a computer mainboard.This does not fit perfectly but may be a good template for the interface structure.


Does anybody know about a package which could fulfil my requirements?

Does anybody have an idea which structure and interface would fit?


Thank you for your ideas.
Sam

start for example with this

Thanks a4z for your answer. As I use the Raspberry as well, this gives me useful hints.

But about the basic structure for me it is not yet clear. Up to now I used /usr or /opt folders to implement my applications. Is it convenient to implement features for external sensors in /sys or /proc?

when you implement a kernel driver, you will possible have some entries in /sys and or /proc but you will nothing copy there, you create files there
https://en.wikipedia.org/wiki/Sysfs
http://www.tldp.org/LDP/Linux-Filesy...html/proc.html

so I think you can stay in /usr and /opt

I suggest you go through some of the Rasperry tutorials from the begin to the end
it will make things
