ISY-99i/ISY-26 INSTEON:Auto Irrigation Program v2

Functionality Highlights

Automatically runs 7 days a week with scaling back based on the weather ie. rain and temperature (WeatherBug).
- Rain above zero inches pushes out the schedule
- Temperature below a set-point prevents running that day
- Temperature high above a set-point promotes daily runs
Manual control is integrated with the Automatic mode ie. auto mode is user interruptable from an INSTEON device.
Manual control to run irrigation and advance forward stations from an INSTEON device.
Each "Station Timer" program also acts as a time-stamp for each station.
Sends a start and finish notification for user tracking purposes.

Variables

Irrigation_Station - tracks which station is currently running, is used for tracking next valve to run.
Manual_Currently_Running - tracks if the irrigation is being run manually, used to prevent an auto run from interrupting a manual run.
Weather_Rained_Last_36_Hours - has rained in the lat 36 hours, used to hold off runs if it has rained.
Weather_Temp_Below_40_Degrees - checks if its below 40 degrees at set start time (11pm), holds off runs if its too cold.
Weather_Temp_High_Above_70_Degrees - checks if the high temp for the day is above 70 degrees, for adding 7 day a week runs if its hot weather.

Evapotranspiration

With the upcoming ISY firmware which will include the new evapotranspiration feature I am thinking about how it will fit into this design. Some ideas are it would be used to control the length of the irrigation station run time. Or it might be used to handle the amount of days the irrigation runs each week instead of using the high temp as the current design does. Or maybe it will replace all the weather part of this code and just make the whole thing much more simpler than it currently is which is always good.

Auto Scheduled Timer -M-W-F-

If
        On Mon, Wed, Fri
        Time is 11:00:00PM
    And $Manual_Currently_Running is 0
    And $Weather_Rained_Last_36_Hours is 0
    And $Weather_Temp_Below_40_Degrees is 0
    And $Weather_Temp_High_Above_70_Degrees is 1
 
Then
        Run Program 'Station1 Timer' (Then Path)

Auto Scheduled Timer S-T-T-S

If
        On Sat, Sun, Tue, Thu
        Time is 11:00:00PM
    And $Manual_Currently_Running is 0
    And $Weather_Rained_Last_36_Hours is 0
    And $Weather_Temp_Below_40_Degrees is 0
 
Then
        Run Program 'Station1 Timer' (Then Path)

Weather Rain Delay 36 Hours

If
   - No Conditions - (To add one, press 'Schedule' or 'Condition')
 
Then
        $Weather_Rained_Last_36_Hours  = 1
        Wait  36 hours 
        $Weather_Rained_Last_36_Hours  = 0
 
Keep the rain status for 36 hours then reset it.

Weather Rain Today Check

If
        Module 'Climate' Rain Today is not 0 "
 
Then
        Stop program 'Weather Rain Delay 36 Hours'
        Run Program 'Weather Rain Delay 36 Hours' (Then Path)

Weather Temp Below 40 Degrees

If
        Module 'Climate' Temperature < 40 °F
 
Then
        $Weather_Temp_Below_40_Degrees  = 1
 
Else
        $Weather_Temp_Below_40_Degrees  = 0
 
This is in a separate program to avoid having the temperature event trigger a false start of the irrigation system.

Weather Temp High Above 70 Degrees

If
        Module 'Climate' Temperature High > 70 °F
 
Then
        $Weather_Temp_High_Above_70_Degrees  = 1
 
Else
        $Weather_Temp_High_Above_70_Degrees  = 0
 
This is in a separate program to avoid having the temperature event trigger a false start of the irrigation system.
