Thanks, your answer is complete and it was the first. Too bad about the docs, but such is Open Source life ;)

Thanks for the hint. I trust that if I open domotiz.db for reading and don't start locking any tables or rows I won't interfere with the workings of Domoticz ...

It looks (but I can't be completely sure) as if Domoticz stores everything (configuration, scenes, measurements) in one single database file:

/home/pi/domoticz/domoticz.db

Does anyone know what format this file is? Are there any standalone applications that can read it?

More in general: is there ...

Does anybody know where and how Domoticz stores raw (temperature) mesurements?
In particular: does it keep everything?

I want to export them for off-line analysis.

@manjh

Great thanks. I overlooked it.

I have several temperature sensors hooked up to Domoticz, and I'd like to adjust the sensor readings to reflect some form of calibration. E.g. a sensor-specific calibration constant.

For illustration see the graph below, which shows temperature measurements taken by 2 separate sensors (different ...

Thanks George and Randy,

Thanks, I'll go with your answer. I wasn't sure if network configuration wasn't somehow "under Domoticz control", seeing as it has a whole section for hardware configuration. Apparently you simply ignore Domoticz and go straight to Linux. Fair enough.

@George
Thanks ...

I have installed Domoticz on a Raspberry Pi model 3B.

It works fine, but at the moment I can only access it by connecting the Raspberry to my home network using an ethernet cable. I was wondering how I can connect to the Raspberry through my WiFi network.

Any hints?
