I'm confused on what FEMS has to do with this? As OpenEMS seems the thing that is being communicated with?

Hi Frenck,

Fenecon is the commercial entity whose product is FEMS (Fenecon energy management system).
All major commits to OpenEMS are FEMS backports (check the OpenEMS source code and look at some random git blames).

99% of the user own a FEMS system, not knowing about the open source project. If I only call it OpenEMS, FEMS owner might not find even the HA integration for their system.

There is a similar "Fenecon2Mqtt" addon. It does not even mention OpenEMS, even though it is based on 100% the same (OpenEMS) APIs as what this integration is based on.

I see it comparable as naming something "Chrome", what actually interacts with the "Blink" rendering engine.
