After reading this column, my started spiking also, thanks alot guys. In my case, the spikes go up, i have had spike readings of -100.00 and 41.26 instead of 30.00 range. Now these readings are taking off of WU and not WL. When I look at WL on the computer, no spikes are shown for that time frame.
MY current setup is such that my logger uploads to WU every 15 minutes by using the upload command at the weatherlink.com website. I am going to try and turn the computer on and have WL do the upload to WU every 5 minutes (which is what I was doing, but was trying to not waste electricity by having the CPU on 100% of the time.)
