All, Here are a few minor enhancements. The instructions for the wild card uploads are in a previous post. This enhancement was suggestion by John Liss. John, can you please incorporate those instructions in to the online manual? Thanks in advance. There are some new tool tip strings you will see when you hover over the Delta Hi/Lo stats that require some explanation. The tool tip will show you the time period between the high and low and the rate of change that was seen between the high and the low. Keep in mind this may or may not match the Rate of Change column that uses a different method for rate calculations and is based upload the highs, lows, and current values. The Rate of Change column is using some time filtering to prevent wild instantaneous rate of change readings where new Delta rate of change does not. Keep in mind if the time stamp associated with the low is older than the high for a particular variable, delta column will be a positive value, and therefore the rate will be positive. Likewise, if the low is more recent that the high, then the delta value will be negative and so will the rate. The idea is that you can look only at the delta value and determine whether the high is more recent (positive value) or the low is more recent (negative value). There is probably little value in looking at variables that change rapidly like the wind speed for example. You might see some crazy value like 650 mph rate of change but keep in mind this can be an instantaneous rate of change if the current wind speed is the high speed for example and the low of say 0 was only 10 seconds ago. The real value of the new tool tips is that you can get a rough idea of the rate of change of variables that change slowly over long periods of time. This is just a rough linear approximation (rate = distance *time). The time unit is hours. The unit for distance and rate of course depend upon the variable you are looking at. For example, if you are looking at the Delta rate of change for temperature in English units, the rate of change will be Deg/Hr. Also note that the rate of change is really only meaningful for a specified time period of less than 24 hours if the variable you are looking at is cyclic. For example if you are looking at the delta column at outdoor temperature, and you want to see how cold it was last night, you would want to set your time range to say 12 hours so that you see the low from last night and not the night before. If you enter say 24 hours, you are not sure whether the low was from last night or the night before. It is possible to use the delta Hi/Lo over periods greater than say 12 hours if you know that a variable (say outdoor pressure) has been steadily increasing over the past 24 hours. You are left to interpret the data correctly. A safe bet is to use the ending time range of 'M' which means since midnight before interpreting the Delta Hi/Lo information. So in summary, remember that the Delta column data and tool tips represent the High, Low, time period from high to low, and rate of change calculation using the time stamps of the High and Low and therefore do not represent the current rate of change. The may match at times if the current reading is the high or low for the specified period. Software Download: WUHU216_32.zip <http://home.comcast.net/%7Ewuhu_software/files/WUHU216_32.zip> --- 24) Added wildcard file support to FTP uploads. With a single FTP action you can upload any number of files matching the wildcard string you supply. 25) Changed the destination for Hamweather uploads from Hamweather.com to PWSweather.com. 26) Added Delta/Hi low tool tips showing the time between the high and low and the rate of change calculation from the high to low.
