Yes - that's good - that means that WD sees the various elements of the 1-wire circuit and will read in the data. Now in the humidity sensors listed on left there should be a ROM ID. copy that and then paste it into the Solar tab, then save again and see if the solar tab developes a number. Tick Use new calculation.
Go to the Extra temp/humidity tab and if there is a second humidity ROM ID (the same one) in there, delete that number, and go back to the Dallas main screen and save again. Check the Solar tab for a number.
If it is dark. shine a torch on it...

Once you get a number there, then you can go to the Solar Icon on Control Panel and setup things in there. You need to enter your Long and Lat again (not if already done on that tab).
Good luck.
