Logging and storing collected data

[kisa]

Hi,

As part of setting up home automation I'd like to store a lot of the data I collect from things like temperature sensors and rainwater tank monitoring for analysis.

What happens to the data once it hits the OpenHAB gateway, is it stored somewhere or just continually overwritten and displayed? I'm sorry I don't have an understanding of how that part of the data flow works.

Is there a way to save it all off, to either analyse at the gateway or scp off to another storage location?

Thanks.

Logging & storing collected data depends on configuring OpenHAB's "Persistence" features.

There are a variety of databases one can use for this.

See this official documentation & internet search (including community.openhab) for more information.

My thread on Displaying Weather Data uses one method of Persistence to make a chart of some weather data.

One Caution: Persistence methods may write a lot of data to storage folders. Some users (not all) feel that this can fill up SD card storage, even corrupt it.

Thanks for the direction papa, I'll have a look.
