N8N Posted August 17 Share Posted August 17 Hello, I'm using my 994i as a controller for my pool I have a contactor that is turned on/off by an insteon switch, and I'm also using a smartenit output relay to allow my pool heater to turn on. the last and most important thing is that I'm using it to control a chlorine dosing pump. I wasn't home today, but it looks like there was a power blip just before the pump was supposed to come on, but when power came back on, the pump started up, after the start time was passed. I thought I had this covered by using the fact that system variables reset to 0 on restart. The pump ran all afternoon and emptied my chlorine tank out. Not cool. Starting the admin console, I see that the folder I have the programs in is set to not allow to run. I have a variable that will not allow the pump to run if the main pump is off, but the main pump was running. All my variables were set to 0 which should have not allowed the pump to start. how can I reprogram this to prevent an unwanted start up and run all day, when the timer is set for 17 minutes? I've attached the log and error log files, plus the folder of pool related programs. Not sure how to add the variables information, but they all say last state change was 9:12:51 AM I really appreciate any help. I'd like to be able to get it programmed such that I can trust it.

paulbates Posted August 17 Share Posted August 17 1) create a separate "dead man" switch program. If status pump is on wait xx minutes. (Something longer than it should run) Set pump off Send yourself a dead man program notification else 2) you can mark programs to run at startup. You may want a program that establishes startup conditions (pump off?) sends a notification, and has no "If" statements. Set it to run at startup Quote Link to comment
N8N Posted August 18 Author Share Posted August 18 I've created a couple programs to try your suggestions, but now that I'm reading page 183 of the manual, I see a couple things. My pump on time is 9:03, and the seeming restart was 9:12, which happens to put it right within the 10 minutes grace period. I want to double-check what I'm reading...If I were to check off the Catch Up Schedules at Restart, then there is no plus/minus for the programs be run? I'm not sure that this was the problem because I don't understand how the wait 17 minutes was essentially ignored. Quote Link to comment
paulbates Posted August 18 Share Posted August 18 Without seeing your programs there's some guessing on my part. If power goes out, the pump loses power too (?) Variables that haven't been saved with "init to" statements in your iox programs will reset to 0 It will help to see the programs here Quote Link to comment
N8N Posted August 18 Author Share Posted August 18 Sorry, I saved the programs, but didn't attach them. How can I create a monitoring timer to count how long the pump is running? If time exceeds allowed, then shut off. pool folder programs.txt Quote Link to comment
paulbates Posted August 18 Share Posted August 18 (edited) I suggest one of these approaches I described above: Maintaining variable state. Right now, when your isy restarts, they''re all being reset to 0. Every where you assign a value to a state variable in a "Then" or else, put an "Init to" statement right under itfor that variable for the same value so the ISY remembers when it resets. Have a program that you set under the programs tab to run at start up and make sure the valves are off (or whatever startup state should be). Different inston / smartenit devices can come back up in different states on a reset. You might have to bench test the program by unplugging the ISY. If you create a deadman program as I described in my first response, you'll want to set that to run at startup too Approach 1 can be a slippery slope and would need more validation testing. A final thought is to have the ISY run a program when it starts up to shut valves off and send you a notification, so it can't over-run and you can be aware and deal with it Edited August 18 by paulbates Quote Link to comment

Are you counting on a variable set to 0 and attached to a folder from preventing the program(s) inside the folder from running? If so, I suggest removing the folder variable and using the variable inside your program. Folder variables can be unreliable, which I think you may have found out. 7 hours ago, N8N said: Sorry, I saved the programs, but didn't attach them. The best way to attach programs is to right click the program and at the bottom of the pop up list select copy to clipboard. Then you can paste the program here. Quote Link to comment
N8N Posted August 19 Author Share Posted August 19 (edited) I set a variable in spring and fall to prevent the programs from running during winter. Everything is unplugged by then anyway, so I would only see if I had a problem via the logs. I was also figuring on if there was a power outage, on reboot the ISY would keep variables set to 0, so I'd have to manually set the variables to a 1 to allow the programs to turn on the pumps, so a bit of both of what you suggest. I'd like to say that the grace period is what outsmarted me, but assuming the log is accurate, the chlorine pump turned on before the main pump, but I thought I was inhibiting that from happening with a state check for the main pump running being required. Here's a C&P of the programs, as I've modified them now... pool_pump_daily_run - [ID 0018][Parent 001D] If Time is 8:30:00AM Then Set 'Pool Contactor' On $chlorine_counter = 0 Wait 11 hours Set 'Output Relay 2 Pool Heater' Off Wait 1 minute Set 'Pool Contactor' Off Else - No Actions - (To add one, press 'Action') pool_chlorine_pump_normal - [ID 0019][Parent 001D] If Time is 9:03:00AM And $Chlorine_ok is 1 And Status 'Pool Contactor' is On And $SLAM is not 1 Then Set 'Output Relay 1 Chlorine Pump' On Wait 17 minutes Set 'Output Relay 1 Chlorine Pump' Off $chlorine_counter += 1 Set Program 'pool_chlorine_pump_normal' To Not Run At Startup Else - No Actions - (To add one, press 'Action') main pump allow chlorine - [ID 0012][Parent 001D] If Status 'Pool Contactor' is On Then $Chlorine_ok = 1 Else $Chlorine_ok = 0 this is a check to see if the pool circulation pump is on. If it is, then we can allow chlorine to run. If it is not then we cannot allow chlorine to run chlorine pump off - [ID 0020][Parent 001D] If $Chlorine_ok is 0 Or Status 'Pool Contactor' is Off Or Control 'Remote 6 Chlorine pump manual' is switched Off Then Set 'Output Relay 1 Chlorine Pump' Off Stop program 'chlorine manual' Else - No Actions - (To add one, press 'Action') Edited August 19 by N8N troubleshooting last night, I set the on-time to 9:03:00PM, correct time intended is AM Quote Link to comment
paulbates Posted August 19 Share Posted August 19 8 hours ago, N8N said: main pump allow chlorine - [ID 0012][Parent 001D] If Status 'Pool Contactor' is On This one may not run after startup, it's a key control and should be set to "run at startup" so you know it's right. All of the programs that use a hard time of day: if those started, and then the ISY restarted from a power outage later, what happens (maybe that's where this began)? Based on how the ISY is set to "catch up" on programs when it restarts in the config tab, different things may, or may not happen. I think the randomness of power outage time will make this hard to be bullet proof. It's probably better to get a notification that the ISY restarted, have it shut everything off so you can manually intervene later and not accidentally over chlorinate the pool 1 Quote Link to comment

I would agree, this may not be the best way of doing this. I would consider changing the hard time of day to a start and end time (to - from). This way they would run during that time frame and then upon power failure, return to the desired position when power resumes. You could also run a disable program from this one to control critical functions (chlorine). By adding a counter when the pump runs, you can send a notification if the run counter exceeds x minutes/hours. The counter can be reset at midnight. Quote Link to comment
N8N Posted August 20 Author Share Posted August 20 Thanks for the suggestions. The odd things is that the log doesn't show anything starting at 830 (the main pump), but then the isy turns everything on after it started up. I guess that's what you're already saying Paul... How to do I do the counter? I suspect it's so easy I can't see it. Quote Link to comment

paulbates Posted August 20 Share Posted August 20 ISY Cookbook Scroll down to pg 120. Your programs have variables, so you've used them. Make a State variable call it Pool Cycle Counter, and then add this iox variable statement: $Pool_Cycle_Counter += 1 ... every time a cycle happens Use that variable, either to send that a notification, or take an action in an iox program If $Pool_Cycle_Counter = > (some hard integer number) Then Send notifications, shut things off, $Pool_Cycle_Counter = 0 Quote Link to comment
DennisC Posted August 21 Share Posted August 21 You can also reset the counter variable back to 0 anytime you want. For example, at midnight, combined with a notification, you can tell how long it ran for, or even program a hard stop if it runs too long. Quote Link to comment
N8N Posted August 23 Author Share Posted August 23 ok, so i start testing....after reading... 8.2.14 recommends using the "control" condition instead of the state condition because it causes a program evaluation each time the control changes... Program to cycle the pump on and off (testing for only a minute for tonight). After the from/to time is all done, I want to turn off the pool heater so that it doesn't shut down under error condition due to no water flow... pool_pump_daily_run - [ID 0018][Parent 001D] If From 9:22:00PM To 9:23:00PM (same day) Then Set 'Pool Contactor' On Else Set 'Output Relay 2 Pool Heater' Off Wait 3 minutes Set 'Pool Contactor' Off I wanted to set a State Variable in a separate program that will monitor the status of the pump contactor. Monitor main pump - [ID 0026][Parent 001D] If Control 'Pool Contactor' is switched On Then $sPool_Main_Pump = 1 Else $sPool_Main_Pump = 0 Unfortunately in the summary tab, this program shows as not ever being run, and the Variable doesn't change to a 1 while the pump is running. What am I missing this time? Sorry if I'm not getting it. this simple part is not working the way I thought I was reading the directions. I will try "status" instead of "control" in the drop down in a minute to see if the behaviour changes. Quote Link to comment
N8N Posted August 23 Author Share Posted August 23 Setting the if condition to "status" is "on" (as opposed to "responding"), and the variable updated. Not what I expected based on the cookbook, but at least I know how to work it now. Quote Link to comment
paulbates Posted August 23 Share Posted August 23 (edited) In your case status is probably more appropriate... the case being the power goes out when the pump is running and the ISY restarts. When the power comes back up, the smartenIT switch is likely still on, its last state, so it won't "switch on" and the program doesn't execute. Power is restored and it continues powering the pump. When the ISY restarts it interrogates every Insteon device for its state, and it will see that the pump is on, so "If Status" will be true. It won't "switch on" during that time and explains what you are seeing Edited August 23 by paulbates Quote Link to comment
paulbates Posted August 23 Share Posted August 23 (edited) Something else to know about "Switched on" in Insteon devices which is a factor too. "Switched on" messages are only sent to the PLM/ISY when you physically flip the switch at the device.... not when you turn it on with a program. "If Status" is the right way to go for this use case Edited August 23 by paulbates Quote Link to comment
