I am comforted not to be alone … 
No, I have not made any particular changes to the names of the devices on the HA side. I don’t remember at least (I have many devices in HC2).
Integration works perfectly for other things. I also manage the Satel alarm control unit well, always connected as a plugin to Fibaro HC2.
Everything is fine except that. I don’t see the device name changes and the new devices on the HC2 side. The situation of the devices seems “frozen”.
I do not know what to say…
