Cannot start the viessmann-mqtt

[electric-m]

Hello there

I installed viessmann-mqtt home folder.
Everything seems to be fine until the point I try to start or see the status of Viessmann Mqtt.

Command is not found?
Is there anything I am missing?

Also, I am not sure, if the init command actually did anything at all.

What I am trying is, I would like to publish temperatures to another already existing mosquitto broker and subscribe to This broker for getting commands to the heater.

Any tips appreciated!

Regards
