Hi Tom I'm using a Davis Vantage. I didn't actually put anything in [[Calculations]] so that's a good point , I don't know if its using hardware or software. I'll change that.
I'm viewing the sqlite database by transferring it to a Mac and using a SQLlite browser program. The values are zero and not Null. I can see lots of other nulls in the extended database fields.
