Error on connecting to one of my valves, and the add on stops

[G-Christ]

Hi,
When the etrv2mqtt home assistant addon tries to connect to one of my valves, it generates this error and the Add on stops.

`'MainProcess' (8), thread 'MainThread' (548024991760):
Traceback (most recent call last):

UnicodeDecodeError: 'ascii' codec can't decode byte 0xc3 in position 5: ordinal not in range(128)`

Any hint on what the cause is and eventually what I can do to resolve it?

Three other valves are working perfectly

Thanks,

I found the cause: the error happened because the name of the valve in the Danfoss app, included a Danish letter “soveværelset” that could not be decoded. I changed the name to “Sove” and it did not crash any more.
