Outletlinc turns on byitself

[swbrains]

Hi,

 

ISY994i Version 4.1.2 (one year old)

 

I installed two outletlinc relays (2473S: on/off only) recently. They are connected from the power source to the first outlet, then from the first outlet to the second outlet. Everything checks out fine with an outlet tester (ground, neutral, hot = OK). Each one has a floor fan plugged into it and the fan is turned on (manual rotary knob) set to low speed.

 

I have them both linked to to a remotelinc2. The A button controls the first outletlinc and the B button controls the second outletlinc. They are linked together in separate scenes in my ISY99-4i to create the "linking" (I didn't link them at the device, only in the ISY). Everything works properly. Each responds to on/off commands from their respective remote button.

 

I have noticed, however, that the second outletlinc turns itself on each day at a random time. I can verify when it turns on by looking at some security camera footage that has it in view. One day it came on by itself at 11:15 am.  The next day it turned on at 10:06 am. There are no ISY events scheduled around that time. I viewed the ISY log but it has no events that turn on the second outlet at those times. The only entries in the log for the outletlinc being turned on are the ones where I was testing it with the remotelinc.

 

At first I thought it might be that the autosense was enabled so I followed the set button steps to disable it. I then removed it from the ISY setup, did a complete factory-reset of the outletlinc and re-installed it in the ISY and re-linked it to the remote. It happens usually once or twice per day, sometimes in the morning and sometimes in the afternoon or evening.  The first outletlinc does not exhibit this issue.

 

I replaced the outletlinc with another one I had in my closet which was a new one (never used) but it happened again.  Again, the first outletlinc stayed off and only the second one turned on, so I knew it was probably not a bad device.  I then switched the fans (both same make/model) to see if it was somehow a load-sensing thing and to see if the specific fan was somehow triggering it on OL 2.  Same issue -- only OL 2 turned on by itself the next day.  I did a factory reset on the device and removed it from ISY and re-added it and it still happened.  I used the set button to make sure load-sensing was disabled and also tested it when enabled and was able to verify the outletlinc turned on with the fan when it was enabled and didn't turn on with the fan if disabled.  Even though it was confirmed disabled, the problem persisted.  

 

I  then tried removing OL 2 from a button B scene on the remotelinc and put it in a scene with button A (deleting the button B scene from ISY) since the button A fan (OL 1) was not exhibiting this behavior.  It thought maybe a stray signal was emulating the remotelinc button B press.  OL 2 still turned on by itself the next day, so the linked remotelinc button didn't seem to matter.

 

Originally I had no programs in the ISY to control it while all this was happening, but ended up adding one to make sure it was off at 1 AM since I didn't want it running all night by itself.  I've posted this issue in the Smarthome forum and after several responses it was suggested that I  had eliminated X10 signals (factory reset), bad device (replaced it with a brand new one) and load-sensing (by changing the setting and confirming it was enabled/disabled), so it might be something related to the ISY controlling it.

 

I did check the device links stored in each of the OL devices as well as the ISY links for each, and there were 4 for each for OL #1 and 5 for each for OL #2 which I thought was odd. I deleted the device and re-added it to ISY and the same scene it was in before (attached to remotelinc button A only) and now both OLs have exactly 4 links each. Not sure if that would account for anything but I did think it was odd.  Unfortunately, I didn't save the link list before deleting/adding it for review.

 

I'd appreciate any advice you may have as to what this might be or how I might do further diagnosis and/or resolve it.

 

Thanks!

swbrains,

 

One test is to unplug the PLM for a day and see if the outletlinc comes on by itself. From what you described it sounds to be location specific since the problem didn't travel with the device when you swapped it with another device from a different location.

 

Please feel free to contact me if you want to go over this on the phone. Support@universal-devices.com

Hi Steve,

 

Thanks -- does that basically rule out the ISY as a cause of turning the outlet on?  Could I also just unplug the ISY to do this or is it better to unplug the PLM only?

 

Thanks!

By unplugging the PLM you take both the PLM and the ISY out of the equation.  If you were to only unplug the ISY the PLM would still be able to send a command to devices.
