Hi,

this Add-on connects to Fenecon’s interface using websocket protocol and uses HA’s MQTT broker to publish a device and sensor entities to Homeassistant.

You can configure all Fenecon(OpenEMS/FEMS) channels and a couple of more things using the container configuration.

Maybee someone find it usefull. Yes, it’s my first Add-On and I’m not a full metal jacked programmer .

Repo: GitHub - Skeletitor/ha_addon_fenecon2mqtt: Homeassistant Add-on Fenecon2Mqtt

Changelog: ha_addon_fenecon2mqtt/CHANGELOG.md at main · Skeletitor/ha_addon_fenecon2mqtt · GitHub

The Add-On comes with a collection of default entities which are pushed to HA. You‘re able to customize those entities. This customization is persistent, it won’t be overwritten by an update.

Have fun

**UPDATE** Here is the new default configuration for requested channels (for versions > 0.2.14). Copy it by your own and merge it into your local config or reinstall the add-on from the scratch.
