where is domoticz plugins directory on synology

[zzlazz]

• installed Domoticz synocommunity package 2020.2-10 on DS218+
• instructions in https://github.com/moroen/IKEA-Tradfri-plugin/readme.md mention domoticz/plugins folder where to clone the Tradri plugin into
• this plugins folder is impossible to find in DSM 7.0 (42218 update 3) as the domoticz package and other synocommunity packages are split in several subdirectories in /volume1: /@appconf, /@appdata, /@apphome, /@appstore and /@apptemp. each of these directories contains a domoticz subdirectory. The /volume1/@appdata/domoticz directory contains a plugins subdirectory which contains the following:

root@DS218plus:/volume1/@appdata/domoticz/plugins# ll
total 0
drwxr-x--- 1 sc-domoticz sc-domoticz 0 Jan 14 11:21 .
drwxr-xr-x 1 sc-domoticz sc-domoticz 144 Apr 1 21:23 ..

you have to sudo -i to access it (root), the normal synology admin cannot.
This seems strange on 2 accounts: having 2 sc-domoticz directories of same name, and that you have to sudo -i to access.

• the instructions for synology in https://github.com/moroen/IKEA-Tradfri-plugin/blob/master/README-Synology.md and https://github.com/moroen/IKEA-Tradfri-plugin must be clarified.
