provided that you substitute IKEA_HOME for the real path to the plugin...

I did. Don't know what's wrong but in the end I can make it work.

Anyway, thank you for your help and the great job you did with this plugin

Best regards

UPDATE :Finally got it!!!
I didn't have the right user/group set in the Ikea-tradfri.service. I tought it had to match /home/pi/domoticz/plugins/IKEA-Trafri folderbut it had to match the /lib/systemd/system/ folder

When nothing works, start again from the beginning...
I did the setup again and now ...

I do close the adapter using ctrl+C because nothing happens.should I wait longer?

2. the adapter is unable to connect to the ikea-gateway (the second line), and is correctly returning this error to domoticz

So is the problem comming from my router? my Gateway ?

How can I bring you more ...

Hello,

UPDATE : just rechecked how i set up everything and i notice that it is said to Clone IKEA-tradfri plugin into domoticz plugins-directory ~/$ cd /opt/domoticz/plugins/
but my domoticz directory is /home/pi/domoticz. So I had to change every command starting with /opt/... by /pi/...
Guess ...
