I am using the indi_sqm_weather driver to connect my Unihedron SQM through ethernet.With KStars 357 the correct server address cannot be saved, while it was saved with previous KStars versions.
The correct server address should be 192.168.0.21 instead of 192.168.1.1
Jasem said he fixed this in INDI recently. I rebuilt last night due to forgetting translations in the previous build which I think you are using. I *think* it should include the fix. Can you download the new dmg located on the download page? See if this is fixed.
