Hostname and MQTT-Sysname differs

[Micha_he]

If I enable 'Append Unit Number to hostname' in newer ESPEasy versions, the MQTT-sysname differs from the DNS-hostname.
DNS is 'NAME-NUMBER' and MQTT is 'NAME_NUMBER' !

Is that wanted and will it stay that way in newer versions?

To answer the last 2 questions.
No and no

I did move all calls to generate a hostname into the same function call, but that does give lots of strange side effects, like you're now experiencing.

So that's enough to change it (soon) to some way of having a checkbox almost everywhere where a hostname is generated to allow very specific choices to decide where to append the unit name.
