Dear all,
we like to use piCtory etc., but it is beginning to become tedious because we have to enter a lot of variables (reading modbus), which could potentially change.
Thus we are thinking about writing directly to the file which pictory creates. As far as I understand it, the file is placed in "/var/www/pictory/projects/_config.rsc" and there is a link to it from "/etc/revpi/config.rsc".
Is the hardware reading its information directly from this _config.rsc or from the "/etc/revpi/config.rsc"? Could the link be changed to another place, at which that configuration file is placed?
Best, Robert
Changing pictory configuration (location)
Re: Changing pictory configuration (location)
PiCtory (the GUI) reads and writes "/var/www/pictory/projects/_config.rsc".
piControl (the kernel module responsible for data exchange with I/O modules and gateways) reads from "/etc/revpi/config.rsc", see the source code.
It's perfectly fine to replace the former behind PiCtory's back as long as it contains well-formed JSON data which can later be read with PiCtory again and which can be parsed by piControl.
If you change the symlink "/etc/revpi/config.rsc" such that it points elsewhere that's fine as well, piControl will just read the file from the new location.

Re: Changing pictory configuration (location)
Good morning lukas,
perfect. That sounds alright.
Do you have an overview or tests for this configuration? I would like to change some parts of the configuration automatically, e.g., ModbusMaster settings and would like to be sure before loading that on the revpi that the configuration is valid.
