barrygordon Posted November 7, 2013 Share Posted November 7, 2013 Operating firmware 4.0.5 ISY 994i I have two Insteon thermostats (2441TH). I have one program that runs at 1AM setting the cooling setpoints to 80 degrees. It runs fine every night with no issue. Both thermostats go to a cooling setpoint of 80 degrees F. The then section is: set 'HVAC Systems / 24.05.B5.1 - Master System' 80 (Cool Setpoint) set 'HVAC Systems / 20.44.74.1 - Guest System' 80 (Cool Setpoint) The second program runs at 6AM and has a then section as follows: set 'HVAC Systems / 24.05.B5.1 - Master System' 77 (Cool Setpoint) set 'HVAC Systems / 20.44.74.1 - Guest System' 77 (Cool Setpoint) The problem is with the second program that runs at 6AM. Which ever thermostat is the last in the 'Then' section does not get its setpoint changed, but remains at the setpoint established at 1AM. If I switch the order it is always the last (second) thermostat that does not get the correct result. Here is the pertinent section from the log file: HVAC Systems / 20.44.74.1 - Guest System Heat/Cool State Off Sat 2013/11/02 10:32:04 PM HVAC Systems / 20.44.74.1 - Guest System Status 76.5?

My iPads which subscribe to the ISY get the correct values sent to them for both thermostats at 1AM and at 6AM. It is just the one thermostat that does not change its setpoint value. I would say it is the thermostat, but I can reliably move the problem between them depending on which entry is second in the 'Them' action at 6AM. Any advice? I have just moved to 4.1.0 so I will see what happens tonight. If it does not clear up, I will try two separate programs, one for each thermostat, at ~6AM spaced 5 minutes apart (0600 AM, 0605 AM). I do not see how it could be a Tstat problem or a comms problem as I can reliably shift the problem between the Tstats. Link to comment
Xathros Posted November 7, 2013 Share Posted November 7, 2013 Try adding a 4 second wait between the two set commands and see what happens. -Xathros Link to comment
barrygordon Posted November 7, 2013 Author Share Posted November 7, 2013 I will try that tonight. Any idea why that might help? Link to comment
Xathros Posted November 7, 2013 Share Posted November 7, 2013 It will help in situations where there is a lot of insteon traffic to prevent missed comms. With wireless devices sometimes having multiple message paths back to the PLM, I have seen odd behavior at times. Not sure this will fix it but I see no other reason that what you are doing would fail. -Xathros Link to comment
barrygordon Posted November 8, 2013 Author Share Posted November 8, 2013 This morning both thermostats were at the correct setpoints. Thanks for the advice. I am using a 10 second delay to allow everything to settle down. Link to comment
Xathros Posted November 8, 2013 Share Posted November 8, 2013 Excellent. Thanks for posting back. You should likely add a delay to the nighttime setback as well. Not sure why that worked when the other didn't but would be safer to add the delay to both in my opinion. -Xathros Link to comment
barrygordon Posted November 8, 2013 Author Share Posted November 8, 2013 I did add the delay to both systems. I suspect on the change in setpoints from 80 to 77 the ambient temperature was above 77 causing the Tstat to start sending additional status info such as the fact that cooling has started. I suspect this additional traffic caused the problem. On the change from 77 to 80 there would have been no additional traffic as the current HVAC would not have changed Link to comment
