Just got my first Polyglot plugin running to get data from my WS-5000 console. I can figure out how to trigger a program when a sensor reaches a particular temperature. What I would like to do is to trigger a program (which opens a window and turns on a fan) when the temperature on the main sensor (outside temperature) is lower than an inside sensor's temperature, and close the window when the opposite is true. I would want to build in a few degrees of hysteresis to prevent too much cycling between open/close.

Is this possible with EISY and Polyglot?

Calc Delta (enabled)
IF
. . . .temp1 < 9999
. . .OR
. . . .temp2 < 9999
THEN
. . . .$intVar = temp1
. . . .$intVar -= temp2
. . . .$sdeltaTemp = $intVar do NOT calculate in variable that continuously triggers CloseWindow or OpenWindow
ELSE
. . . .--

CloseWindow (enabled)
IF
. . . . $sdeltaTemp > 2.0
THEN
. . . . do close window process
ELSE
. . . .--

OpenWindow (enabled)
IF
. . . . $deltaTemp < -2.0
THEN
. . . . do open window process
ELSE
. . . . --


ANYTHING IS POSSIBLE with polisy or eisy.

Thanks. I hadn't figured out how to assign Polyglot nodes to variables - that was the missing piece.

@mikewu99 Nothing to add, but how is your window automated? I started this incredible journey with automating the (16) windows of my summer room in mind. I replaced the horrid windows with casement windows, but the original inspiration is unavailable/obsolete, so this project has been very back burner. Thanks.

I added these to two brand new awning windows. Controlled through a Bond Bridge. I was able to hook them to the windows without drilling holes or otherwise modifying the windows other than removing the crank operators, so no voiding the window warranty.

@larryllix the programs are working after I figured out that $sdeltaTemp needs to be a state variable (I assume that's what the "s" prefix means). I added code to disable OpenWindow and enable CloseWindow when OpenWindow runs (and vice versa) to prevent the window motors from being energized every time the temperature changes. Also prevents the ISY from overriding me if I manually open or close a window.

@mikewu99 Thank you for the response. Gives me something to plan.
