Looks great! I do have to say one thing though. The acurite you are using is not a probed one. You need a probed one like the acurite 00891 for the uth. You have to put the probe of the one I mentioned under the substrate on top of glass over the uth to get the correct temp. The one you have is just measuring ambient which isn't giving the correct temp of your uth. Unless you have an ir temp gun that you were able to check the temp under the substrate.
