And with the right names assigned to the virtual sensor it is finally working!

And replace the path to avoid this error:
Error: ...l/domoticz/scripts/lua/script_time_intergasincomfort.lua:36: cannot open /home/pi/domoticz/scripts/lua/JSON.lua

Oh yes: the right path on synology is: /usr/local/domoticz/scripts

I now have the files in the right directory using busybox/telnet (CP command under Admin) I first tried to put the files in the LUA directory using the root account, but Root access for telnet is blocked default. I now want to figure out how to use these files within domoticz. I already setted up ...

I try to add the LUA scripts to my Domoticzon Synology. I cannot reach the right directory?? Can you please give some detailed instructions in setting up the LAN2RF on Synology??
