Yes, then it can be ignored. There are some generic parameters for which values are fetched from the CCU on every startup. But not all devices have those parameters. Hence the warning message.
The state you see is accurate. Some devices have the parameter on different channels. Basically Home Assistant asks for the same parameter on different channels. And if a channel doesn’t have the parameter, it responds with the warning you are seeing. So everything is working. Warnings like these can pretty much always be ignored if they happen during startup. If they keep popping up after startup, then it’s a problem.
