Thanks Xathros that's a very straight forward approach. I'll give it try. I wonder if you have a similar approach to using the Wait command. I'd like to load the Wait time from a variable but this hasn't been supported. I think it still isn't in 3.2.6. I've seen some ideas posted on the forum but they always seemed to require several new programs and I just wasn't interested in that much of a work around. I decided to wait until the functionality was added to the ISY. -phil

I'd like my irrigation to run every other day. Any ideas on how to schedule that? I thought of maybe using odd and even calendar dates but I don't see that either. I have several irrigation programs stashed away in their own folders and now that Spring is here I need to get them running again. Last year I just scheduled them to run according to the day of the week. That's ok for the most part but I do have some special zones that would really do better running every other day, I don't care what day of the week it is. I'm using the ISY-99i v 3.2.6 and the EZFlora irrigation insteon module. I also have Homeseer as the main interface to my Insteon devices through their http user interface. I do some scripting in Homeseer and have many Events configured to do all my lighting control but decided to do the irrigation program in the ISY 99i. thanks, -phil

I would prefer variables as well. I'm still using version 2.8.16 of the 99i and it doesn't support variables. I run each Zone from it's own program that way I can see the progress of the watering routine as it moves from Zone to Zone. I store my many different watering routines in separate folders to keep them organized. Basically I program the THEN path in each program as DNL points out. Like this; If Then Set 'IrrigationZone.1' On Wait 30 minutes Set 'IrrigationZone1.' Off Wait 3 seconds Run Program 'P2Z2Run' (Then Path) Else This example is the program for Zone 1 where it runs for 30 minutes and then commands Zone 2 to run which is in the P2Z2Run program. It's all pretty straight forward. -phil

dnl - I forgot to add that the programming technique in your post has helped me greatly. Until that I had very few ideas on how the ISY was suppose to program. thanks, -phil

I wonder how this technique would change with the introduction of variables that are in the next release? I quess it's will still be a "state machine" but with variables to use between the states.
