FrozenPinguin,
Thanks.
This week I'm going on holiday. After that (may be about 7 weeks) I'll try to order for the cups. I have already tried to understand the Norwegian language. I recognise some words, perhaps I shall you ask later on for some help to guide trough the orderpages.
But I have also thoughts to change totally the weatherstation. Due to the rain sensor shows some problems at this moment. The reception signal is disappeared after a cloudy day. I suppose that the rechargeable battery has gone, but otherwise the backup batteries are renewed. That is strange. The WMR928 system is of 2005.
