I would be interested in knowing about this as well - since the 2433A3 is discontinued.

Cool! Thx a million to everyone for all your help.

I think I can solder it on the existing fan wires. Was thinking more about how to connect to the relay you mentioned and then from their to the I/O Linc input sensor.

How would I wire that up with the existing wires on the fan (sorry if I asking too much) ?

I just need to know if their is power to the fan - to be able to convert that into a dry contact for the I/O Linc sensor input.

It's a 24v fan. Not sure why it says DC24v - the fan is used in a circuit board which is powered by 240v AC.

Do you have any details on how to "convert" the current on the fan circuit into a dry contact circuit which could be used with I/O Linc?

Trying to understand the meaning of "dry contact closure". I am trying to detect if a small low power fan (like the ones in a computer) is on or off. Can the I/O Linc sensor input be used for that ?

I agree and thx so much for the explanations. But I still believe the order of the events matters - when turning off the light switch manually, if the second program is triggered after the first program it can't work IMO When I turn off the light switch, the light status is now Off and I am also causing the motion sensor status to become On (since I am passing by it). So program 1 will trigger (because the motion sensor is now On and the basement light status is now Off) - so the light will turn on. If Program 2 runs before any of that (because of the light Control is switched off), then program 1 is disabled for 1 minute (in which case the motion sensor status will become Off within that time range) so when reenabling Program 1 after one minute - the conditions of Program 1 are not met anymore so the light won't turn on. If Program 1 is triggered before Program 2 then it would be too late - the light will already have been turned back on. I am starting to think Control events are handled before Status events which would confirm why it works. Not trying to be difficult just trying to understand...

I understand that it's event based but I still think the order of the events has an impact. To turn off the light manually at the switch I have to pass by the motion sensor so the motion sensor will become On and after I press the switch the status of the basement office light will be Off - so Program 1 will run again unless Program 2 runs first which disables the Program 1 for one minute (giving time to the motion sensor to become Off). I don'r see how this would work without having that order.

Based on the suggestions I created another program : If Control 'Basement Office Light' is switched Off Then Disable Program 'Turn on basement office light' Wait 1 minute Enable Program 'Turn on basement office light' Else - No Actions - (To add one, press 'Action') This seems to work however I am wondering if it's just by chance since for this to work, the execution order of the programs become important. This program has to run before the 'Turn on basement office light' program and it does, but I never specified any execution order of the programs. Can program exec order be specified or are they just run alphabetical order of the program name ?

I have a motion sensor and created a program to turn on a light when motion is detected (see below). This works fine, however when I turn off the switch manually, the program kicks in again (because motion is detected again) and turns the light back on. Any way to get this to work? If Status 'Motion1-Sensor' is On And Status 'Basement Office Light' is Off And From Sunset To Sunrise + 1 hour (next day) Then Set 'Basement Office Light' On Else - No Actions - (To add one, press 'Action')

Thanks so much - I will give that a try.

Yes - the state variable does change back to 0 before the 1 minute is up. I would have thought that the Wait 1 Minute would prevent the program from reevaluating the IF. How would I go about getting the desired behaviour ?

If $GarageDoorSensor is 1 And From Sunset + 15 minutes To Sunrise (next day) Then Set 'Garage Exterior Light' On Wait 1 minute Set 'Garage Exterior Light' Off Else - No Actions - (To add one, press 'Action') The 'Garage Exterior Light' turns on properly when $GarageDoorSensor variable is set to 1 but does not turn off after 1 minute. Any idea why ?
