your name: statement should give a name in the system - it may be because you are not using western characters that it is having a problem, or that it needs to be the first line after platform:
You can also change the friendly name of the device by adding a customize: section up in the homeassistant: section of your yaml file. I only just discovered this recently - you cannot override friendy_name in the device setup itself but in a customize block
Yes the experoment shows that this is due to the use of none western characters.
name doesn’t need to be in the first line.
So the only option for now is to use the western characters for the entity name and just override them in the customize section…
Wonder if automatic transliteration can be implemented… Added a request on github
