This seems to be related to the custom sensor that you have set. I think the requirements got changed slightly and there is an update pending. Other users proposed a change already. Will look into it.

Instead of using the neerslag-card that requires the setup of custom sensors, you could also use the neerslag-app, which is an all-in-one package. It contains both the neerslag-card and the sensors.
