Garagelinc sensor problem

[sumguy]

I am fairly new to ISY and am not sure why I am having this problem. Any assistance would be greatly appreciated.I have a garagelinc kit installed that has been functioning flawlessly for 3+ years. I have an ISY994i PRO on firmware 4.3.6.

 

Recently the sensor status is randomly reporting incorrectly. Doesn't happen often but it did alert me last night at 3AM that my garage door was now open. Didn't notice the alert until around 5:50AM, when I checked my phone. Got my heart rate up a bit until I checked the camera in the garage and saw it was still closed. I refreshed the sensor and then it reported correctly again.

 

This is not happening all of the time. The status has been incorrect maybe 3 or 4 times over the last 3 weeks. This is the first time it happened at night.

 

Below is the log from last night. Does anything seem out of ordinary here?

I also ran level 3 event viewer and queried the sensor.

Any idea what could cause a random false sensor status?

 

Thanks in advance!!

1. Do you have trigger reverse enabled in the I/O Linc?

 

2. What type of sensor do you have? The little small one offered currently by Smarthome or the larger SECO-LARM 226L-3 unit?

 

3. Open and close the GDO five times and watch the status of the *Sensor* does it reflect the correct state? Perform a query and confirm the state of the sensor does not change.

1. Trigger reverse is not selected.

2. I have the larger Seco-larm sensor.

3. The state of the sensor was correct each time. 

 

The ISY reports the status of the sensor correct almost every time. The incorrect status has only happened approx 3-4 times all within the last 2-3 weeks.  I have had the device for approx 3 years without any problems prior. The incorrect status doesn't happen when I actually open or close the door. It happens when the door has been idle just like in my logs above. It was the middle of the night and I was asleep. The other times were on the way home from work, I pulled up my garage in Mobilinc to open it and it showed that it was already open when it was physically closed. Each time I confirmed that the ISY had the incorrect status in the logs. Can't figure out what is causing it to randomly and infrequently cause the status to incorrectly change.

Make sure the magnet is within normal sensing range of the sensor.

You may want to GENTLY tap on the switch and see if it is intermittently changing state and verify the connections are tight on the IOLinc's connection block.

[sumguy]

The magnets are about 1 cm apart at the top of the garage door. I have the magnets screwed in so they won't move.

 

I will double check the connections when I get home.

A 1 cm gap between switch and magnet is large (1cm is equivalent to 0.39370 inches).   I strongly suggest moving the magnet to no more than 1/4 inch at the full closed position.
