TJF1960 Posted June 4, 2009 Posted June 4, 2009 As I understand it when the ISY-99 reboots and the “Catch up schedules at Restart†box is checked in the configuration tab, any programs with “if†statements that are true will run? I have at a program that at 3:30 AM sets the coffee pot on. Within the program is a timer which turns the pot off, so there is not an end time in the If statement. So when the ISY reboots the coffee pot always turns on, regardless of the time of the reboot. Is it because there is not an end time in the If statement which will cause the program to run at startup? If I go to “Program Summary†tab I can right click on the program and select “Disable Run at StartUp.†Will that prevent that program from running at reboot even though the if statement is true? If so will I have to go to “Program Details†and enable the check box for that program to run its normal daily schedule, or is it just disabled for startups? I noticed if you select Enable at Startup an “On†will display in the column for that program, but there is no positive indication that the “Disable†is selected. I thought perhaps an “Off†would be displayed. Which is what led me to these questions. As always, thanks for your time, Tim
Michel Kohanim Posted June 4, 2009 Posted June 4, 2009 Hi Tim, First of all, I do not think you would want to check Catchup Schedules at Restart. This was put in there only for backward compatibility with older installation. What this does is that it runs all the schedules for that day. So, your 3:00 AM coffee pot program will run at start up. Secondly, using an exact time for sensitive programs is not advised. It's always best to use a duration even if only for a minute. All and all, I think if you uncheck the catchup schedules at restart, you will be OK. With kind regards, Michel
ResIpsa Posted June 4, 2009 Posted June 4, 2009 I don't want to hijack Tim's thread (even though he hijacked my name ), but I was wondering if Michel could expand a bit on his comment that sensitive programs should use a duration, not a specific time. I've been using an ISY for 18 months now, and this is the first time I've heard that recommendation. For example, would you recommend I replace this current program (which often leaves at least one entry light on): If Time is Sunrise Then Set Scene 'Outside.Entry Lights' Off Else - No Actions - (To add one, press 'Action') with this one: If From Sunrise For 1 minute Then Set Scene 'Outside.Entry Lights' Off Else - No Actions - (To add one, press 'Action') Again, apologies for jumping in.

Chris Jahn Posted June 4, 2009 Posted June 4, 2009 Hi Tim,Secondly, using an exact time for sensitive programs is not advised. It's always best to use a duration even if only for a minute. This is not correct; it should have been qualified as saying do not use exact time if the program is set to Run at Startup (we're looking into the bug). In all other cases, using exact time is fine. When you use an exact time, the Then Path will run when that time is reached (the program is set True). Nothing else happens, and thus the program will always remain True. When you use a time range, the Then Path will run when the From time is reached (the program is set True). When the To time is reached the Else Path is run (the program is set False). Note: If you add other conditions such as LampLinc status, etc.. this may affect which path is taken (Then or Else). --- ResIpsa, Unless your program is set to Run at Startup, you do not have to change anything.
