Hi @hek and @scalz
Thanks for your response. I have been unable to locate the guide I thought I previously found... So I probably misread that.
Thank you for the clear answer - which leaves me with only one more ( at the moment )... If I install OpenHAB - will it be able to hand out id's via MQTT? I noticed that the clients without an id keep posting to MQTT... under node id 255...
