Hi

i had to replace my ECU-B with a new one.
Used the replace ECU function in the app.

But now i need to add the new ECU to HA.
When i try i get this error message:

First thought is that it's just a message, received data does not contain the expected END signature. Might be caused by all kinds of things like firmware upgrade. Leave it running for a while and see what happens. You can also put the integration into debug mode, that might give some additional info.
