Addition to integration.

[bazanben]

Is there any chance this would get updated to support the river 3? While I am unsure how to do the code portion I would be willing to test configuration as I have the river 3

I just received a River 3+ and would also like to assist, if pointed in the right direction.

i have a standard River 3 and i will receive a River 3 Plus next week, i'm available too to give some needed informations to add these devices

The new River 3 series is communicating with protobuf messages, which are not documented. But the telegrams may be decoded by educated guesses knowing the working conditions.

There is a workaround using the HA MQTT discovery feature and using an instance of ioBroker (another homeautomation system).

I have made a small picturized description.
I hope it helps
