Hi, I have the same problem, no connection to my Vaillant VRC900 for two weeks now. After I had contact to the Vaillant Support I received the following answer (translated)...

Same problem, same solution. Since the update to HA 2025.2.5 no data of myVaillant, after disabling the EEbus data collection under "configuration" the problem disappeared after reloading the device.
