Please test https://github.com/MichaelDvP/EMS-ESP32/releases/tag/latest
ignoring the telegram if it does not contain a valid errormessage.

It doesn’t look like the latest build has fixed the bug. The non-ascii character is still in the UI and in the JSON.

Now I had to restart the s32 in order to activate telnet, the error is gone 🤔

[proddy]

closing this one then, fix will be in Michael's upcoming PR and 3.7.1

It looks like the error has come back in 3.7.2.
