I have a 2350 and I agree that many 23xx parts are interchangeable.
However, I have a similar problem, but with the anemometer, it stopped during a 50kt plus storm (I live on an island off the SW coast of Ireland) so I thought it was kaput. A week ago it woke up and worked with WD for 24hours and then stopped again. I then began to examine the base station and noted that the time was wrong and that there was no automatic wireless update icon visible. I reset the unit but same thing. I have had a look at the hygro unit but it seems to be OK, a few cobwebs, nothing else.
My question, is the unit faulty? I have the remotes directly connected, and on ac power, no batteries. Is there any fix for the time input and /or is it related to the anemometer issue??
Thanks for any advice. Barry
