Hi
If anyone is interested or could find it useful I’ve uploaded a Home Assistant add-on that takes the Batrium UDP stream, publishes key data to MQTT with Home Assistant auto device discovery.
Installation instructions are on the GitHub but it’s basically add a custom repository in the add-on store, install it, very minimal configuration and you will have a home assistant device and entities available.
It’s open source and of course free to use, hope someone finds it useful.
