in response to MIN MAX, posted by Lorne
First.... remember that the WEL doesn't do averages.... just long term filtering... close, but not the same.
That said... I was torn between putting a min/max pair on a single accumulation, or putting a day/month pair on each accumulation.
Since the two values normally represent day/month values, I stuck with that
Either way was a compromise... but you can still do what you need with a few expressions. To get several different accumulations, just duplicate the sensor value...
eg: assume you want to get min,max,ave for outside temp:
Assume the existing device name is TO (Temp Outside).
Then setup some expressions to copy the TO value to three new devices:
ONE = 1 << a constant expression
TO_MIN = TO * 1 << copy To to TO_MIN
TO_MAX = TO * 1 << copy To to TO_MAX
TO_FILT = TO * 1 << copy To to TO_FILT
Then turn on the various accumulations for these three copies...
ie:
Set the Accumulation for TO_MIN to "{"
Set the Accumulation for TO_MAN to "}"
Set the Accumulation for TO_FILT to "F"
So now the WEL will post the following values:
TO_MIN_D Daily Min Temp....
TO_MIN_M Monthly Min Temp....
TO_MAX_D Daily Max Temp....
TO_MAX_M Monthly Max Temp....
TO_FILT_D Daily Temp Filter (near average)....
TO_FILT_M Monthly Temp Filter (near average)....

This site is all about building a cool, energy efficient house, that makes maximum use of earth sheltered design, passive solar heating and cooling, geothermal exchange energy management, and right sizing of the house for it's designated use. The home's placement is on a south-facing hillside in Deep Creek Lake, Maryland. This site describes the design process, the technologies used and the expected results. We also have a comprehensive Links Page for anyone who is also interested in designing a similar project.
