Switch Link ON/Off Switch weird behavior

[pauliep]

I have had my ISY/994 for over a year. I have programmed it to do several things, with the one program that has to work being a bathroom fan for my wife (don't ask).

 

The program has been working for over a year, but as of yesterday, the program no longer works. Here is the program:

 

If

Status 'Master Bath Fan' is on

 

Then

Wait 20 minutes

Set 'Master Bath Fan' Off

 

Else

Set 'Master Bath Fan' Off

 

What is now going on is when I hit the Switch Link in the bathroom, the bath fan will stay on forever. It doesn't shut off after 20 minutes. If I access the ISY/994 control panel via my computer, it "sees" the Switch Link as being off. However, when I control the Switch Link via the control panel, I have full access to the range of commands (On/Off, etc.)

 

I am not sure why this is happening now, but would appreciate any advice or help.

When you go to the Admin Console, check Programs tab -> Summary.

Find your program, and see what its status is. If you turn the light on while you are watching, it should flip to "Running 'Then'" and show "True" for the status.

 

Also, do you see the status in the Admin Console update immediately when you turn the switch on?

I didn't think to check that when I was originally diagnosing the problem. So, I went ahead and checked.

 

When I hit the actual switch in the bathroom, the Summary does not show "Running Then" or "True" in the display. However, when I use the control panel to turn it on, I then see the "Running Then" and "True" in the display. Likewise when I use Mobilinc.

 

I can't explain this issue. Any ideas?

Sounds like the ISY isn't getting the notification that the device was turned on or off locally.

 

When you toggle the switch locally, does the status update (not just the program running)?

 

You might try resetting/restoring the device…the link record to the PLM might have been corrupted?

When toggling the switch (physically going there and turning it on), no, it does not update on the control panel. If I turn it "on", the control panel will report it is "off". If I use the control panel, however, to turn it "on", it reports it is "on" and shows my little program running.

 

I tried unplugging the ISY/994 and replugging it back in, but it didn't seem to work.

I meant reseting/restoring the switchlinc..not the ISY. Only do this if you don't have any manually created links, or are willing to recreate them. Any links managed by the ISY will be restored.

 

Usually you pull the Set button out, wait 10 seconds, push the Set button back in and hold until the long beep stops, wait a few seconds, it double-beeps, and turns on.

 

Then go to ISY, right-click the device, and click "Restore Device"

OK, tried to do as you had written. No luck.

 

In exasperation, I deleted the device on the control panel. I then hit the switch on the Switch Link mode, setting it into link mode. I reinstalled the device. I then went to the program and had to reinsert the device with the new name and parameters. I tried it out, and it worked. I was surprised.

 

Not sure what was happening, but I hope it doesn't happen again.
